Water Pump 4 Cyl Removal/Install
[Saab 900 2.0T, 900 2.3NT, 900 2.5i, 93 2.0T (not sedan), 93 2.3NT, 93 2.3T Viggen]
Removal Instructions: (there is another removal proceedure at the page bottom)
| STEP 1 | Drain the coolant via drain cock or a hose. You can speed up the process by removing the cap of the reservoir. This is the first edit to the instructions for replacing a 1999 93 2.0 turbo sedan water pump. You should "depressurize and drain cooling system in an environmentally responsible manner" Be careful, as coolant might be hot. |
| STEP 2 | Remove the Air cleaner and the intake hose (on turbo cars plug the pipe with a rag) |
| STEP 3 | Remove the bypass hose (on turbo cars remove the pipe from the throttel body to the intercooler) |
| STEP 4 | Use a rachet extension and pull back the tensioner and put a 6mm drill bit in it to hold the tensioner back |
| STEP 5 | Remove the steering pump and let it hang over the top of the radiator and remove the hoses from the pump |
| STEP 6 | Remove the coolant pipe in the engine front left corner |
| STEP 7 | Remoe the throttle body hose from the coolant pipe and the screws from the thermostat housing. You can them move the pipes to the side. At the point you can also remove the Boost control valve |
| STEP 8 | Remove the pump and the sleeve with the orings |
Installation Instructions:
| STEP 1 | Clean the sealing surfaces and fit the coolant pump to the pump housing. |
| STEP 2 | Lubricate the O-rings with an acid-free Vaseline and fit the sleeve together with the pump. |
| STEP 3 | Refit the boost pressure control valve (turbo cars). |
| STEP 4 | Refit the coolant hose to the throttle body and refit the screws on the thermostat housing. |
| STEP 5 | Refit the screw which holds the coolant pipe to the front left-hand corner of the engine. |
| STEP 6 | Reconnect the coolant hoses and pipes to the coolant pump. |
| STEP 7 | Refit the steering servo pump with its bracket and put the belt back. |
| STEP 8 | Relieve the belt tensioner of strain, using a ratchet handle extension, and remove the drill bit/or the like |
| STEP 9 | Refit the pressure pipe between the intercooler and the throttle body and refit the bypass hose (turbo cars). |
| STEP 10 | Refit the intake hose (turbo cars) and refit the air cleaner. |
| STEP 11 | Make sure that the drain plug is in tight. Fill with coolant and check the system for leaks. |

This is another take on the 2.0 liter water pump replacement instructions. I have recently done a 1999 93 2.0 turbo 4 door sedan coolant pump.
- 1. Remove air filter cover, and the three 10mm bolts holding the air box to the inner fender and remove.
- 2. Remove the single bolt holding the exhaust manifold heat shield on and lift to remove.
- 3. Remove the belt by putting a 12 inch or more x 1/2 inch socket extension into the 1/2 inch square hole on top of the tensioner bracket and pulling toward front of car. A flex or ball headed extension works best.
- 4. Remove the two 13mm mounting bolts holding the power steering pump to it's bracket. Wiggle the pump up and down and it will come out. Fold it towards the left side of the car out of the way.
- 5. Remove the three 13mm bolts holding the pump bracket and remove.
- 6. Remove the 10 mm bolt holding the turbo cooling pipe to the back of the pump.
- 7. Remove the large coolant hose from pump outlet and the small turbo coolant hose from the pipe.
- 8. Remove the three 13 mm bolts holding the pump to the block. Two are on top and one underneath the bearing housing.
- 9. Gently prying at the back of the pump with a 1/2 inch extension between the pump inlet housing and the left end exhaust manifold bolt head whilst wiggling will dislodge the block to pump O ring sleeve. Only allow the pump to move forward about a 1/2 to 3/4 of an inch, and then the pump is pulled towards the right side of the car to dislodge the turbo coolant line O ring sleeve from the back of the pump. The pump will now be free to remove from the car.
Separate the pump body from housing by removing the 7 torx bit screws. Carefully scrape the mating surface on the pump body. You will be replacing the bearing housing and impeller only. The inlet /outlet housing will be reused. Replace all pertinent O rings.
