Purchasing a used Saab can be a coin toss. Reality is that Saabs are very good cars as long as they are taken care of correctly. More often than not people who purchase high end cars just can't afford them regardless of who makes them. Above all things the number one thing to look for is whether or not the individual changed the oil at 5000 miles MAX. We know that some of the recommended service intervals are 10,000 miles but we have seen so many engine issues because of this that we flag any oil changes longer than 5000 miles. Everyone says that oil can last 15,000 miles etc... That may be true but not every car is designed with the type of oil change interval in mind. Most cars have exhaust components right below the engine oil pan which basically cooks the oil in the pan. This heat alone can be catastrophic to the life of engine oil or transmission fluid. You can pull the dipstick out and look at it closely. If it is very dark color (brown) at the base of the dipstick then that is a good indication that the heat has gotten to the dipstick enough that it has baked the oil in the lower part of the engine as well.
You can count on having some issues with Saab ie.... DI Cassettes, Belt pulley issues, Fan speed resistors, SID unit failures etc.. but in the grand scheme of things they are excellent automobiles if maintained correctly.
A special thanks to Matt Hoffman for the contribution of this material!. Kudos to Matt! I did find that using a several step process of the Meguiars' Fine Cut Cleaner #2, followed by Show Car Glaze #7, and two coats of High Gloss Wax #26 I was able to make a lot of really good progress on my '91. There is no clear coat on it that I can find, except on the left front fender which I think was replaced before I got the car. All the products mentioned are in the tan bottles and I used a Craftsman 6" orbital buffer for all applications. I tried a 10" but it was useless except on the roof and parts of the hood. There are just too many curves on the classic 900 to use such a large pad. The cleaner #2 did a really nice job of gently removing the oxidation without going too far. There were still water marks visible after using the cleaner #2 but the #7 glaze appears to have helped blend them in. It's possible that a reapplication of the #2 could eventually remove the water spots, or a rubbing compound, but I'm not ready to give that a shot. Over the past two years I had used the Meguiars ColorX cleaner wax, and on the third use it did make a difference, but the underlying faded paint seemed to nullify the wax after about 5 weeks.

AC Compressor clutch replacements usually cost more than compressor replacements because of the cost of the clutches and the cost of the labor added together. In most cases you end up getting a compressor that is about the same cost and may not last as long as a new one. This is why we do not sell compressor clutches.

The low side port is on the largest line and the high side port is on the smallest line. Typically the high side line is the smaller of the two lines and has the highest pressure running through it.
The amount of freon needed in a Saab AC system is from 2.5lbs to 3.0lbs of freon to properly fill the system. When filling you can watch the site glass on the receiver drier or expansion valve to figure out when you have put in enough freon. Once the site glass goes from milky to clear then the system is full.
Several things can cause your AC fuse to blow when turning on the Air conditioning. The most likely cause of a Blown AC fuse is a frozen or burned up AC Compressor clutch. When this occurs the heat from the burned up compressor clutch often causes the compressor bearing to seize up and burn the AC belt off. Compressor replacement is the only repair!
Another reason can be a short circuit caused by the cable that runs to the compressor (In Saab 95-2004, it is a single and shielded one with blue
plastic lining. This cable runs from a connector located at right upper side behind the front engine panel, directly down to the AC compressor). Check this cable for any damage caused by friction with metal pipes. I solved the problem using isolating tape. Compressor was in perfect working
condition and no dismantling was needed at all. after "Cable repair", no more blown up AC fuse (10A) occurred.

AC lines problems occur on any car with AC. This is the is the weak spot in every AC system. The lines begin to leak where the aluminum part of the lines run into the rubber line. If you grab the junction with your hand you can sometimes twist the two parts where they are crimped together. When a hose has failed there will usually be a thin oily substance at the junctions of where the hoses come together.

Pricing for AC HOSES (ac parts)
Leaking Hydraulic hoses can often be attributed to a leaky clamp which cause the hose to be able to be turned. You can repair some hoses temporarily by cutting a small 1/4 slice of the metal fitting out (being careful not to cut the hose) then put a adjustable hose clamp over the (now cut) fitting and tighten down the clamp. What happens here is that you cut just enough of the metal clamp out that when you put the hose clamp on and tighten it down that is basically creates a new clamp over top of the one that started leaking. This is a great quick fix and may last a bit but replacement of the hoses with new is the best long term solution.

A roaring noise that can be heard when turning on the A/C can generally be attributed to a faulty A/C Compressor but can also come from a faulty A/C idler pulley (2.0 Liter engines). Both components fail on a consistent basis on the 1985 and up 9000's. Compressor failure should be done by a professional technician only. Idler pulley failures can be identified by removing the belt and turning the idler by hand to see if the bearing has failed!

Remember Feeler Gauges? Gently slide a lubricated 4 thou feeler gauge under the emblem, carefully push it through the adhesive. Do it again slightly further round. When you've done about a third, move up to a 6 thou gauge (easier, more sturdy). When you've done about half, use a thin bladed screwdriver to lever it up a bit (I padded mine with some thin plastic). You can then easily cut through the rest of the pad. Took less than 10 minutes, and no marks on hood at all. I then removed remainder of adhesive pad with on old face cloth and petrol (not recommended I know, but that is all I had to hand). Worked a treat. Less than 15 minutes after starting, a perfect finish.

Interior Smells: Leaking evaporators or Heater cores can cause coolant leaks to soil the carpets causing musty smells. Leaves in the false bulkhead under hood cause AC/Heater drains to clog causing odd interior odors. Clogged sunroof drains can cause water to backup and leak through the interior.
Clogged drains can be cleaned out by accessing them through the false bulkhead (in some cases where the cabin filter is). The sunroof drains are most often located in the same place under the false bulkhead but can also be located just below the windshield glass under the hood. AC drains are typically in the right from fender well. You can clean most drains by CAREFULLY pushing a bent coat hanger up the drian to begin clearing the debris.
The most common thing to cause the lower seat to stop on the way back is coins in the seat track. When this happens it can cause good bit of trouble depending on the position of the seat which many cause one to have to remove the seat track to get the coin out. We have also seen power seat control modules cause the stop and go of power seats. Check the connections to the motor to see this is your issue.
In the event of a sunroof motor failure you can shut the sunroof manually. There is an Allen key in the overhead console where the sunroof motor is located which can be inserted into the sunroof motor and turned manually to close the roof itself. On 1979-1994 Classic Saab the sunroof can be closed from the trunk.
Water leaking into all 4 floor boards can usually be attributed to the AC drain coming off on the right hand side of the firewall but can also be caused by the following issues. They are listed in order of importance to check:
1 - AC Drain tube has come off in the firewall on the right side (refit to repair)
2 - Sunroof drains are clogged causing water to seep in around the seal (unclog by blowing air through)
3 - Sunroof seal has deteriorated causing it to leak (replace the seal)
4 - Body weatherstrip mouldings have come off causing water to come in
5 - Antenna drain is clogged causing water to get into the trunk. Refit or unclog the antenna drain (usually in the trunk area)

The term ABS means Anti-Lock Breaking System. The ABS System automatically controls braking at the front wheels individually and the rear wheels as a unit (in most cases) preventing the wheels from locking during a hard braking situation. This enables the driver to maintain STEERING control and also shortens the distance to a complete stop. In cars without ABS, the brake master cylinder actually applied steady pressure to each wheel when the brakes were applied causing the wheels to look under heavy breaking. This led to wheel lockup, loss of steering control & lengthy stopping distances. ABS systems use a hydraulic pump that applies modulating pump pressure during heavy braking. The ABS system in effect pumps the brakes for the driver a consistent frequency. This pulsing is considerably faster than even the most experienced driver could accomplish if he were to attempt to this manually!

Black dust on the rims usually comes from the type of material that the brake pads are made of. Most factory pads are made of a very soft material to prevent brake squeal. The real problem with that is softer means more dust. Harder usually means more noise. The absolute best thing we have seen to prevent dust is ceramic pads. Keep in mind that there is NO such thing as a pad that does not create dust. They all do. Some less than others. Ceramic pads seem to be the best overall combination to prevent noise and dust.

There is a couple of things that could cause your brake caliper not to clean the brake rotor correctly. The caliper piston is stuck meaning the caliper must be replaced. The 2nd thing it could be is that the hydraulic line leading to the caliper has gotten swollen inside meaning that the fluid can longer enter or exit the caliper correctly. Replacement of the line is the only cure.

Saab does not recommend turning rotors because the majority of time after turning them they are below Saabs recommended minimum thickness. The recommended minimum thickness is generally stamped on the rotors! This is not to say that Saab rotor cannot be turned. They can be turned one time but will generally warp within one year because of how thin they become!
Pricing for BRAKE ROTORS STANDARD (brakes & related)
One of two reasons. Reason 1 - The pads that were used are an inferior grade pad. Usually, an inferior grade pad will make its presence known by noting a very high pitch squeal when applying the brakes. Reason 2 - The brake pads that were used are hard use pads which contain a type of material which will cause this noise to occur. It does not mean that there is a serious problem. It simply means that it is the type of materials contained within the brake pad. Only cure - replace the pads! Hard use pads will generally not cause damage to the rotors but the noise can be somewhat consistent!
NOTE: We have also noticed that brake scrubbing sound could come from a worn wheel bearings. Although the sound is different it does sound close enough that one could confuse the two.
Pulling left or right can be caused by numerous issues which include: Sticking brake calipers, faulty brakes hoses (that are swollen from within) and faulty brake master cylinders. In most cases it is caused by a sticking brake caliper. Depending on the application some calipers can be rebuilt and in other cases the faulty caliper must be replaced. If your vehicle is equipped with ABS brakes you may find that the valve body in the ABS system is malfunctioning or a proportioning valve is bad.

Upon applying the handbrake the force if transmitted to the handbrakes via two cables (one on earlier models but it was superceeded to the two cable setup depending on the car). Each cable runs to one rear wheel. When pulling on the lever the cable being pulled tightens the brake pad against the brake rotor/drum. The handbrake warning lamp also comes on until the arm is released.
There are several common cruise control failures on Saabs. The pedal switch failures are the most common problem. What generally occurs is that the pedal switches become mis-adjusted or the ears get broken off the switches causing a no contact condition. Another common problem is that the cruise vacuum hose leading from the vacuum pump under the false bulkhead begins to crack where the vacuum fitting is located at the firewall.. The third most common failure is an intermittent functioning cruise control module. This can often be identified by noting that the cruise will work intermittently (900 & 9000 only).
Another Issue: On turbo models, there is a vacuum controlled switch, located near the pump (red cap) that cuts the signal to the APC solenoid valve when the cruise control is on (switch opens). If the switch is faulty (I broke mine on rough road), it can keep turbo boost at the "basic" level even if the cruise is turned off. The APC boost gauge will only go half-way into the yellow region, and performance will suffer. Either replace the vacuum controlled switch or pull the pigtail connector below the switch and short the ends of the yellow/white wire going to the APC solenoid valve and
proper turbo boost should return. Be aware that if this second fix is employed, your turbo is not limited in boost when in cruise control.
A Faulty wheel speed sensor (WSS) will also disable the cruise control due to it's ability to monitor vehicle speed. In addition, faulty WSS will also disable ABS function, traction control (TCS) and the speedo; all relying on the signal from the WSS
Air bag lights (SRS) are often triggered by the horn contact ring in the steering wheel or because of faulty sensors. The only way to turn out a Air Bag Light is to take the car into your local Saab dealer and have them turn out the light and diagnose the problem. After struggling with the airbag light for a long time I found out, that by isolating the control unit (below hand brake lever) from the car body (negative) my system functions without errors.
The Alarm remote communicates with a control module located under the drivers front seat. The range is typically around 25 feet depending on the type of transmitter that you have. The left button is used to arm or disarm the car. The right button is used to lock or unlock the trunk.
The battery life is about 3 years under normal use. Use the distance at which the remote functions to determine the battery strength. On the newer cars the SID unit will read "REPLACE KEY BATTERY" when the battery warning is activated by the remote. To replace the batteries simply push off the back housing by pressing downwards. On the newer remotes you may have to insert a small pin on the side of the remote housing to release the cover or remove screws on the back side of the remote. Remove the batteries and replace them. Most newer remotes are powered by a 3V lithium battey. You can buy them at radio shack. After the batteries have been changed you must press the remote 5 times in a row to re-activate the remote.
NOTE: If the remote is being replaced by a new one you will have to marry it to alarm unit by going to your local dealer and having them program it to the alarm module allready in the car.
Here is a list of problems occured to my Saab 900 SE Talladega Sensonic of 1997, caused by a dirty light bulb:
- Check engine light on (air/fuel mixture)
- SID with all the possible messages of the rear taillights
- Can't run over 2800 tr/min, the engine goes down
- Can't press down the gas pedal, the engine goes down
- Cant use reverse gear, the engine goes down -can't use the brakes, the engine goes down
- Direction lights always on, if I use it the engine goes down
- Headlamps always on, if i shut off the switch, the lights don't shut down, but the engine... Yes: It goes down!
After one day of terror, I decided to replace all the bulbs: The bulb of the rear foglight was wrong! I cleaned it, I refitted it, and all the car returns to normal! It happened in March and the car still run perfectly.
Electrical door component failures. What we mean here is that more than one electrical component on a door fails at the same time. For Example; window won't go up and down, door mirrors won't move, door won't unlock, central lock won't work, etc..... When this happens you will likely find that the connector where all the wiring runs to the door is either broken or just pinched. Some cars have a connector and some cars just have wires that run through a rubber grommet. Checking the wiring and repairing it should cure the problem.

Sometimes a low battery in the key fob can cause these issues. Replacing the battery is an inexpensive first option to see if that fixes the problem before getting the dealer involved.
In-Order to test for electrical drains on the battery you need to place a Test light between the negative battery terminal and the Actual battery cable with the two disconnected and then pull one fuse at a time until the light goes out. What ever fuse or combination of fuses that causes the light to go out will tell you where the drain is coming from. This will tell you where the problem is and you can address whatever component or relay that is causing the issue.
Replacing the fog light bulbs can be more difficult than people think on a Saab but it is not terribly hard. In most cases the bulb is located in the back/bottom of the fog light itself. The difficult part is removing the skid panel just below the fog-lights. Skid panel screws located in the fog-lights must be removed to access the bulbs. The skid plates and screws are under the car which means they can be tough to get out....
Almost every vehicle has headlight adjusters on top and bottom of the back of each light assembly. Most dealerships and independent repair shops use headlight aimers to adjust the headlights. It can be done without aimers by adjusting the beam of light to be directly in front of the assembly and about 24 inches off the ground. You can measure this by aiming the lights at a garage wall and making the adjustments. You will find that one of the adjusters will adjust the light beam vertical and the other adjuster will adjust the light beam horizontally. Some headlights have levels located in the lights assemblies. These levels should be adjusted at 0 unless otherwise specified by the owners manual.
When you open the hood of a Saab a light will come on. There are two ways the lights are turned on. One is manually turning on the light by moving the switch to the on position (much like the trunk lights). On later models, hood lights are activated by a mercury switch that is built into the light assembly itself. If your hood light will not come on you likely need to replace the light or the bulb.
Interior lights that work intermittently can often be attributed to a faulty ground at the door pin switch. At the front of the door frame there will be a small push in pin with a rubber housing around it. Peel back the rubber housing and tighten the screw to the frame. Check to be sure the screw to the door frame is tight. If it is then replace the switch.
We have seen some issues with the Central Processing Unit for the Onstar causing the hazard lights to come on and stay on. When this happens you cannot shut them off without disconnecting the battery. The problem is that water gets into the Central Processing Unit which causes this issue. There are two possible fixes. If you do NOT use Onstar then you can disconnect the two wires to the unit and the problem will go away. If you DO use onstar you will need to replace the CPU.
It appears that Onstar is going to a Digital system (instead of analog) on Jan 1st 2008. Here is why, FCC rules require that cell towers support both digital and analog signals until the end of 2007. But starting in 2008, the cell towers will no longer have to support analog so OnStar is hanging up on the 500,000 of its 4 million OnStar customers who have older analog units. Consumers with a 2003-2005 vehicles will need to update their OnStar system using an adapter that will cost approximately $200. (At this point we are not aware of an adapter for Saab but once there is one we will carry it and list it here.) Unfortunately there is no adapter available for cars prior to 2001 which means that you cannot use onstar any longer.
Poor radio reception can usually be attributed to a poor antenna connection at the radio itself or at the antenna in the rear. The cable typically plugs into both components and if it comes loose the reception would be poor if at all. Remember, if you remove the radio you will need the radio code to get the it working on again which requires a code from the dealer. FYI, many techs use to write the radio code on top of the radio to prevent them having to find the code for the installation.
If you are experiencing odd electrical issues in a single circuit such as lights, ignition, switches etc.... be sure to pull each relay and look for faulty connections where the relay plugs into its holder. It is common to see corrosion where the connectors and the relays meet. This is usually caused by poor ground connections to a the relay. This can be fixed by cleaning or replacing the connectors and securing the grounds correctly.
Turn signal issues are fairly common on most vehicles. The problem can come from something as simple as the bulbs being burned out (usually noticed by the turn signal flashing fast) or by the turn signal just not feeling right inside the car. If the turn signal switch does not feel normal then it is likely broken and must be replaced. Another issue that does occur is the failure of the flasher relay or blinker thinker. In most cases the relay failure will cause the turn signal to come on solid without blinking.
Turn signal switch issues are fairly common on all cars. They typically exhibit issues with lights not functioning correctly or turn signals inoperative. Replacement of the switches can be accomplished by removing the bottom cover and then removing the side switch screws. A tip here is that almost all turn signal swithes have wires in the back that are held with tie wraps to the steering column. You may have to remove those before being able to pull the wires far enough out to replace the turn signal switch.
Washer pump failures are typically caused by debri that gets into the washer tank and gets pulled into the pump when turning on the washer squirters. We have seen tons of issues with both the washer pumps failing and the valves that protect the pump as well. You can test the pump by removing the hose from the pump and pulling the handle to activate the washer squirters. If water squirts then the pump is good, if not you can test it further by removing the pump and applying voltage directly to the pump to be sure it works.
Cleaning the engine compartment is fine as long as several necessary precautions are taken. Be careful not to pressure was directly at the distributor or directly into the wiring harness. Don't use carb cleaner or items such as this around the harness as harsh abrasives will peal back the wire coating in the future. Try not to spray directly into the harness where water will collect and stay for long periods. If you feel that you have gotten the wiring connectors wet simply remove them and squirt a small amount of dielectric grease into them and reconnect.
Engine oil consumption is an indication that something is wrong either with an engine oil leak, internal engine ring problem or Turbo issue. The most common problem is excessive bushing clearances in the Turbo causing oil to leak into the intake manifold. Replacement of the turbo is only cure. Engine ring problem means replacement or rebuilding of the engine. External engine oil leaks would require locating the leaks and repairing them.
A word about Anaerobic sealant. If you touch it on the outside then it will always be tacky because by definition the word Aenorobic means "pertaining to or caused by the absence of oxygen" this means that it will never cure until oxygen is removed. Saab began to move away from common engine gaskets in approximately 1993. They began to replace timing cover and oil pan gaskets with anaerobic sealant. These types of sealants work well on machined surfaces.
NOTE: When using these types of sealants you don't want to slide components together you want to apply sealant to both items and then apply them together. As mentioned before the outside edges of the two pieces will likely never harden.

Leaking Hydraulic hoses can often be attributed to a leaky clamp which cause the hose to be able to be turned. You can repair some hoses temporarily by cutting a small 1/4 slice of the metal fitting out (being careful not to cut the hose) then put a adjustable hose clamp over the (now cut) fitting and tighten down the clamp. What happens here is that you cut just enough of the metal clamp out that when you put the hose clamp on and tighten it down that is basically creates a new clamp over top of the one that started leaking. This is a great quick fix and may last a bit but replacement of the hoses with new is the best long term solution.
The intake system is composed of an air filter, mass air flow sensor, connecting pipes/hoses, turbo unit and intercooler. The system is connected to the throttle body on the intake manifold. The air filter, which is located on the right-hand side of the engine bay, removes particles from the incoming air and also acts as an intake silencer. The mass air flow sensor provides the engine control module with continuous information on the amount of air consumed by the engine. The mass air flow sensor signals are processed by the control module, which monitors the air-fuel mixture of the incoming air.

A roaring noise during belt rotation (without the A/C on) will often be caused by an idler pulley bearing going bad. There are occasions where Alternator bearings will also create a roaring noise during belt rotation. In-order to diagnose either of these problems simply remove the belt and rotate each of the pulleys by hand. The pulley failure will make itself apparent by noting that the noise begins when rotating the faulty pulley.Belt Removal should be done by authorized personnel only! Danger!

For many years oil pickup problems have cause a variety of engine problems on Saabs. Oil pressure issues, Main/Rod bearing issues, Timing chain issues etc..... We are seeing even more problems with the oil pickups getting clogged up on the 93.95 cars now that the oil replacement recommendations have increased. We are seeing more and more issues with the lower ends of the engines beginning to scream or make a high pitches whining noise due to low oil pressure to the upper end of the engine. When the timing chains are being replaced we HIGHLY recommend cleaning or replacing the oil pickup tube as well. We also do NOT recommend changing the oil at intervals that are higher than 5000.00 miles. Not everyone runs synthetic oil all the time and synthetic is not available at every store in the world.
One of the most overlooked oil leaks is cracked valve covers. If one is not very careful when using an impact wrench on valve cover bolts they can actually crack the cover itself right around where the bolt goes into the valve cover. When this happens it can cause a very bad oil leak that is difficult to trace because the leak would only happen when the engine is running. You can usually spot the crack by looking very closely at the hole in the valve cover. If a crack exist there will usually be a little of colored line leading the bolt head. Replacement of the valve cover is the only cure.
Recommended service intervals really depend on what year and model that you have. The earlier 99, 900 & 9000 used the 30,000 or 60,000 intervals and in the mid to late 1990's the intervals changed to 35,000 & 65,000 intervals. In the 2000 and on era the 10,000 miles service intervals seem to be the standard. We typically recommend just changing the oil at no greater than 5,000 miles and doing major maintenance at about 30.000 mile intervals. We have developed service kits that help you get all the part without having to look them up individually.

The most common problem with smoke coming from the engine compartment is a leaking valve cover gasket. The rubber gasket hardens which causes it to leak on the exhaust manifold (depending on the Saab you have). The only cure for this is to rpelace the gasket.
NOTE: When replacing the gasket you should only use sealant at the front base of the valve cover gasket.
The throttle when shut should have a very small gap which allows a little air through when idling. What generally occurs is that the throttle gets coked to a point where there is no longer a gap. When this happens it can cause the car to stall when coming to a stop or when letting off the throttle quickly. Cleaning the throttle body with carburetor cleaner and a tooth brush can cure stalling if the throttle body is dirty but vacuum leaks are the most common cause of stalling.

I have noticed that if you turn the throttle body manually from under the hood without aid of the cable, the low idle gets altered and can cause your car to idle too low causing it to stall upon take off. A quick disconnect of the battery will appearantly allow this to reset and idle correctly. Hope this helps someone. 2002 9-5 Arc 3.0 V6 wagon. I found out that my throttle body was in limp home mode which locks the cable to the butterfly instead of the drive by wire settings . This overrides the normal settings, causing the car to idle too low and stall on take off. The Throttle Body Replacement article by the Platonoff's explains this and was very helpful in me resetting the throttle body. One thing to note is that the CEL codes must be reset in order for throttle body to operate correctly . A quick and easy way to do this is to pull the number 17 fuse from the fuse panel, wait a few minutes then replace it and start the car. Otherwise the computer will pop the little wire on the throttle body back to limp mode and you are back where you started. Thanks for the great how too articles. I was able to change my thermostat and waterpump myself last weekend, saving me 1,300 bucks!
Tightening torques are important in certain situations but not quite as much as most people think. In general most engine gasket torque for bolts is around 12-18 psi (not headgaskets). The truth is most bolt positions do lend to one being able to torque the bolts to the correct specifications in the first place. A general rule of thumb is that if you tighten the bolts with regulator hand wrachet and you have tightened the bolts to a point that you cannot turn the wrachet anymore then you are pretty close. The most common issue with any typical backyard technician is overtightening the bolts not undertightening. Remember to use gasket sealant only in places that seem logical to have it like corners of pans, covers etc..... We have seen issues with people overtightening valve cover & oil pan bolts and breaking the covers themselves.
In Most cases faulty Converters can be identified by noting that your car will not accelerate or seems to have severely diminished power. Many times converters that are clogged up will glow red when the vehicle is running. The reason for the Glowing is because of the amount of heat and unburned fuel that collects in front of the clogged up converter. Converter replacement is the only option. A quick way to be sure that the converter is the problem when it is suspect is to disconnect the exhaust system at the header and allow the exhaust to flow without going through the converter. If the converter is the problem the cars power should be restored with the header pipe disconnected.
NOTE: There is always a cause for a clogged converter, either excess fuel from a faulty part like and ECM, Injector, wiring issue, Oxygen sensor etc....... We have seen issues with the platinum in converters breaking loose which causes a rattle but other than that converters that get clogged have to be related to a failure in the fuel system or possibly the ignition system.
Exhaust Diagnosis: The most common Exhaust failures are mufflers. You can often easily diagnose issues with the exhaust system by placing a rag or towel over the tailpipe hole (Just for a few seconds). BE CAREFUL AS THE EXHAUST MAY BE HOT!!!!! When you cover the tailpipe hole up for a few seconds pressure builds in the exhaust system and a whistling noise will begin to occur wherever your exhaust leak is.
Exhaust Purpose: The exhaust system is designed to carry away the engine's exhaust gases with a low flow resistance, low noise level and a long operating life. The exhaust system is composed of two parts: a front part with a catalytic converter, and a rear part with two mufflers. Both mufflers are a combination of resonance and noise absorption material. The system is delivered seamless via one unit. For spare parts there are three different sections: a front section with flexible pipe, a center section with a front muffler, and a rear muffler. The exhaust system is held up by six rubber mounts from front to back. The exhaust system is protected against corrosion because of all the parts except the outer plate of the front muffler are made of 12-18% chrome steel. The outer plate of the front muffler is aluminized. This combination gives very good corrosion stability. Heat shields are fitted above the exhaust system's most heat intensive zones to protect exposed parts where the heat radiation can otherwise cause problems.

On just about every Saab made the gaskets that go between mufflers and the header pipes have the flange gaskets built in. Chances are that if we do not have them listed on our site in the picture diagrams then they are not needed. You can generally assume that about 1989 they are built into the pipe (all but the Classic 900 cars 1979-1994)
A harsh smell coming from the exhaust can usually be attributed to the use of fuel that contains methanol (Although in most places it is not supposed to be sold). When using this fuel, a sulfur smell can be emitted from the exhaust which can range from a mild odor to a rotten egg smell. To avoid this smell try changing the place where you purchase fuel! Catalytic Converter failures can also cause this same smell!
I have a 1995 Saab 900SE 2.0 turbo. The car would be slow to start. The idle would bounce up and down between 1000 and 2000 rpms when at a stop light.I changed the bad vaccum hoses and checked for air leaks. The car still had idle problems. I had to replace the battery. With the new battery the car now runs correctly. Check the battery for charge when idle problems occur. The electronics for the fuel system can be affected if the current is incorrect. Typically the section that requires the most current will be the one to starve the most. The first to surfer is the ignition then the fuel system.
In the early Saabs the sensors were located in the exhaust manifolds and could be removed from under the hood. As the engines evolved the sensors were repositioned to the header pipe and then later moved to just before or after the catalytic converters. In every case you can count on the sensors being located in the exhaust because that is where the oxygen content in the fumes can be measured from.
When changing any major cooling system component on a Saab you will need to get the air out of the cooling system. In most cases there is no coolant nipple to bleed the air. The easiest way to do that is to remove the coolant reservoir cap and run the engine. Once the thermostat opens the air will cirulate through the cooling system via the waterpump circulation. Once the bubbles disappear from the coolant reservoir you can install the cap and the air should be removed.
The typical Saab cooling system holds about 1 gallon of antifreeze mixed with distilled water 50/50. This is a general rule and may be slightly different depending on the year vehicle you are servicing.
In most cases the radiator drain plug is located at the bottom of the radiator on the passenger side. You will usually have to remove the plastic skid plate below the radiator to access this plug. Another way to drain the radiator and in some cases and easier way to flush the system is to pull the lower radiator hose.
Graphite powder is an excellent lubricant and seems to remove gummy substances from ignition lock or door lock cylinders. Lock cylinders typically come with grease in them so don't clean them unless absolutely necessary. If they are gummy then clean them first with substance such as contact cleaner then put dry graphite into them. The cylinder should begin to work properly unless damaged internally. If it is damaged internally replacement is the only cure.
If the ignition switch is bad, not only may certain electronic devices not automatically turn off, some may not go on. I had a bad ignition switch, and the remotes would not work, and the alarm would not go on. The radio would also stay on after the car was shut off and the doors were opened.
Be very careful when replacing bulbs in the turn signals and taillights. We have seen issues when people install multi filament bulbs in single filament bulb sockets and visa-versa. One of the issues that we have seen is that the vehicle will run on when turning the ignition off or will not start at all. Keep in mind that different symptoms could occur with different cars. This may or may not apply to your particular Saab.

I can verify this problem in my 2003 9-3 linear with different bulbs in the rear tail lights the entire car lighting system from the exterior would flash like a police cruiser and my car would not start. Once the bulbs were replaced with the correct bulbs the car started fine.
Whether or not a spark plug is pre-gapped is determined by the manufacturer of the spark plug. In most cases the plugs come preset but I would always check them to be sure they are correct. It would be silly to have to pull each one out because you did not take a few seconds to check them for accuracy. Remember that an "ounce of prevention is worth a pound of cure"

A whining or high pitched whirring noise that occurs at initial start up can often be attributed to a faulty starter assembly. Most of the time when starters fail you will begin to detect a funny odor coming from the starter area. The smell comes from the wires on the armature or shorting causing the epoxy on the wiring to melt within the starter.
Thanks to Rick Blake for contributing to this FAQ!
Starter noise continuing after engine starts, or a higher-pitched grinding can be caused by the ignition switch not returning to the 'Run' position. If the ignition switch binds in between the 'Start' and 'Run' positions, the starter is apparently still engaged. Another symptom to look for is that the power windows won't go up or down.
Backing up the car seemes to bump/jump If your car seems to jump or bump when backing up then you could have a problem with the Air Pump on your 97X. Aiir compressor failure is a common problem and it is located in the right reaer quarter panel. Replacement is the only cure

There are several ways to tell if your vehicles front-end is out of alignment. One, is that the steering wheel may appear to be of center (an indication of something bent or tie rod ends off center). Second, your car may pull to the left or right when on flat ground (an indication that the alignment is off). Third, Front tire wear is an indication that problems exist in the front-End. This could mean that the caster or camber is off and in need of adjustment.
Front End Noise and rattle is mainly due to the clearance between the spring, thrust bearing and mount. The excess clearance causes the thrust bearing to move around, they are constructed of a durable plastic and bearings but this clearance destroys them. Purchasing a new strut kit will solve this problem. Saab is aware of this problem and you will notice that the 03 thru 05 Saab struts have been superseded by a revised design. TheSaabSite has what you need at a reasonable price, no they're not paying me but when you buy something and post a technical reply I believe they give a discount. So I am at work replying :) and I just purchased sway-bar bushings and the caps that go over them so they don't make noise in the winter, you know the squeak. Saabs are great cars when they work, Saab should give me a new one for all the money I have spent :)
Front wheel bearing issues can often be determined by loading the wheel that is suspect for the bearing to be bad. By turning the wheel left or right this will place the weight of the vehicle on or off of the suspect side. If the noise increases with load then you must replace that wheel bearing.
If you hear a grinding noise while driving and turning slowly check the dust shield and the bearing. Most common is bearing and should be replaced if needed. Also check to see if the tires are cupping on the inside as this will be noisy.

Question: Hello, I have a 01 9-5 aero, and now that it is nice out I'm driving with the windows down, and have notice that when I turn left it makes a grinding noise like my tire is rubbing on something. From as far as I can tell the tire is not rubbing on anything. So today while I was putting some wash fluid in I banged on the tire and heard it rattle, this kind of alarmed me. So here are the symptoms. Only makes a grinding noise when my steering wheel is at/above a certain left turn. DOES NOT make the noise on right hand turns. any ideas please help!
Answer: 3 things to ck is to look at the dust shield if it is rubbing take a screw driver and push it back then look at the pads make sure they are not to the wear indicator. The last thing to look at is the wheel bearing if they go bad you will hear noise when loading the weight of the car on that bad bearing while turning.

The most common cause of power steering noise is a fluid leak. Leaking fluid causes the pump to whine due to lack of lubrication in the pump. In most cases the whine can be fixed by locating the leak and repairing it but in cases where the pump is ran dry for extended periods the pump may have to be replaced. The lines are the the most common leak area. They usually leak where the rubber line turns into the metal line. If you can turn the two parts of the lines seperately that is where the leak will be in most cases.

Shocks-Struts Trying to determine if you Shocks-struts need to be replaced can be difficult. Most of the time when the shocks get worn out you can tell by pushing down on each corner of the car. If the car bounces more than once when it returns to the rest position then it likely means that the dampening effect of the shock is worn out. This would mean that you would need to replace the shocks. Replacing them in pairs in not required but is preferred in-order to keep the dampening the same on both sides.
Springs Most spring failures can be identified by noting that ride height has changed. If you notice that the height of the front or rear or even one corner is not correct then the likely problem is a broken/worn spring. Replacing them in pairs in not required but is preferred in-order to keep the ride height the same on both sides.
A Wandering feeling in the steering can often be attributed to faulty tie rod ends. Tie rod ends are the components that Tie the wheels to the steering racks. When they have excessive wear they tend to cause the tight steering feel to disappear. When replacing Tie rod ends be careful to count the amount of turns that it takes to remove the ends and place the new ones on using the same amount of turns. This will insure that the tow-in remains the same.

The tie rods also connect to the rack and pinion unit with rubber bushings that usually fail within 100,000 miles. When these bushings wear out completely, the tie rods are allowed nearly 1/2" of free play. The bushing kit costs under $20 and can be easily accessed at the center of the steering rack. Often when the bushings are worn, you can easily tell with a visual inspection.
Tires for less money: Next time you need tires on your 900NG or 9-3 (1998-2002) you may save up to $160.00 or more with this information. Saab specifies a "VR" rated tire (130mph ) and tire shops may require that you purchase a VR if they install your tires on the car in their shop at the time of tire purchase. But if you just use the car around town or do not exceed freeway speeds for extended periods of time, a "HR" rated tire (up to 130mph) will fit and work fine and save you up to 35% when you go to purchase new tires. The tire shop MAY require you to bring in the rims OFF the car at time of purchase to install and balance the tires, but then you can drive the car back to the shop with the new tires so the shop can verify the installation and activate the warranty for the tires (I already did this). I discovered this last time I purchased tires from a major national warehouse chain for my 900NG [with over 200K miles] that we use as a spare car around town. I saved $160. off the purchase of 4 Michelin-Brand tires buying the HR vs. VR (OE size). I have about 10,000 miles on these tires with no sacrifice to handling or ride quality. Additional information: I do NOT tow with the car and I do NOT operate the car at maximum load capacity.
Leaking Hydraulic hoses can often be attributed to a leaky clamp which cause the hose to be able to be turned. You can repair some hoses temporarily by cutting a small 1/4 slice of the metal fitting out (being careful not to cut the hose) then put a adjustable hose clamp over the (now cut) fitting and tighten down the clamp. What happens here is that you cut just enough of the metal clamp out that when you put the hose clamp on and tighten it down that is basically creates a new clamp over top of the one that started leaking. This is a great quick fix and may last a bit but replacement of the hoses with new is the best long term solution.
We don't typically suggest buying used transmissions because of the amount of wear associated with its moving parts. Transmissions typically last around 100-175,000 miles but anything after that is a "gift". This is not uncommon with any car as all transmissions have the consistently moving parts which wear out quicker than stationary parts. We do have a used parts division that can supply used transmissions but the warranty is no more than 90 days in most cases.
When your wiper arm (windshield, trunk wiper or headlight wiper) won't move the most common issue is a loose nut under the wiper cap at the base of the wiper arm. When the nut gets loose the arm cannot move the because their is no compression to hold the arm tight to the shaft of the motor. In most cases you can tighten the nut and it will start working again. There are situations where the arm has been reemed out to a point where the wiper arm will need to be replaced to correct the problem.

There are two covers just below the headlights that previous Saab owners would assume are the headlight washers-wiper slots. The covers only serve as a possible future place for headlight wipers or washer squirters. Headlight wipers or headlight washers do not currently come on new models with Headlight wiper in the USA but they do come standard in some countries.
