Changing the Water Pump on a '95 SC
This was borrowed from the Bonneville Club
This is information about how to replace the water pump on a 95ssei. I’m sure that other years will be pretty close. When doing this remember where you put all of the bolts, and make sure you get everything back in the right position. If you see right or left anywhere in the write up I’m talking from the perspective of sitting in the drivers seat, not standing in front of the car.
1. Remove the negative battery cable
2. Jack up the car on the right front, remove the tire and the guards. This allows easy access to some of the bolts you’ll need to get out.
3. Next take off the skirt on the front of your car, because you’ll need to get around that to loosen the butterfly nut to drain the radiator.
4. Drain the radiator of coolant. The nut is on the left front of the car, and is a little hard to get to.
5. Take off all of your belts, try to remember where they go.
6. Now comes the fun part… Jack up a piece of wood under the transmission and the oil pan. You only need it to support the right side of the engine. Once that is done you can remove the engine mount, half of it will come off don’t worry about the other part, you can move it around as needed.
7. Once that is done take off the four bolts that hold on the WP pulley, and remove that pulley.
8. Take off the idle pulley’s that are in the way of the water pump bolts.
9. When you get here you should notice that you can get to all of the bolts…….. But one. You’ll see that the mounting bracket that mounts the PS pump and alternator is covering one of the bolts.
10. To get to the bolt, you must remove the alternator completely. There are a few small bolts too that hold the mounting bracket in place. Be sure to get them all. You’ll have to remove the heater core hoses to get to one of them.
11. Then you need to remove the PS pump. You can leave the pump in the engine, but there is a bolt you need to get to directly behind it.
12. After you have loosed every bold you can find. There is one more. This one is on the side of the bracket, and you’ll have to access it from under the wheel well.
13. You should be able to slide the whole piece aside now, and have access to the last water pump bolt.
14. Remove the bolts from the water pump, than take the water pump off.
15. Clean the old gasket material off thoroughly, but be careful… these parts are aluminum.
16. Attach the new WP remembering to put on the new gasket, and use some sealant, because you don’t want to take it apart again for a leak.
17. Reattach the bracket, the PS pump, and the idle pulleys. This will be the easy part… just take you time and try to find the best order to put the thing back together with.
18. After the bracket is in place, reattach the heater core hoses, put the pulley back on the water pump, and replace the alternator.
19. Now reattach the engine mounts. Your engine should now be supported so you can remove the jack from the oil pan/transmission.
20. Replace both of your belts, and reattach the negative battery cable.
21. I recommend flushing out the radiator, then tightening up the butterfly nut to stop the flow from the radiator.
22. Fill your radiator up, than start your car. You’ll want to do this a couple of times as your radiator sucks down some coolant.
23. After a couple of times of doing that when your radiator is cool. Replace the cap, and let your car get warmed up. After it is warm loosen the screw just above the thermostat to clear all the air out of the system.
24. Once that is done check your coolant level again, and add as needed.
25. Now replace the front skirt, and the protectors around the wheel.
26. Set your baby down on all fours again, and take her for a test drive.
I hope I got every step in here. I think that everything is complete. This job will take you a long time, anywhere between 5 and 8 hours. It took me about 7. Good Luck. Is a PITA, but better than paying someone $300 bucks to do it.
