How do you remove the water pump on a 1994 Oldsmobile Cutlass Sierra?

Answer 1

Answerget under the the car,beneath the gas tank. the fuel pump will have 4 wires coming from it and a couple hoses (it is on the front of the gas tank). the base of the pump is flat and round. disconnect the 4 wires where they are joined and label them . next, with a screwdriver, loosen the hose clamps and disconnect the hoses leading from the pump. then , take a flathead screwdriver and a hammer.( the round face has grooves sticking outward from the base); position the screwdriver against the round plate so it catches, then tap at a counter-clockwise direction. this will loosen the pump and it will lift up and out of the gas tank. don"t let anyone try to tell you the tank has to be dropped. that is not true. it is a 10 minute task . AnswerSorry if this comes out wrong, but the asker was wanting the water pump, not the fuel pump. The water pump is located on the front of the engine and is driven by the belt. Can't be 100% without looking but it should have hoses from the radiator or engine to it. To remove it, there will be somewhere between 2 and 4 bolts that hold it on. You will have to replace the gasket and put a bead of silicone sealant after replacement. If you are unsure of your abilities, you may have to ask someone with more experience for more help. If you have a family mechanic they will most likely give you specifics without charging you.

Answer 2

Crack loose (don't remove) the water pump pulley bolts then use a 10 inch adjustable wrench and rotate the idler pulley arm CCW to relieve the tension on the belt. The tensioner arm has a boss on the casting that can be used to seat the wrench. I have seen some arms with a 3/8" square hole cast into the arm to accomodate a breaker bar drive instead of having a boss with flats. Relieving the tesnion will allow the belt to slip off the grooved pulley. Remove the belt, remove the pulley nuts. This will allow access to the pump mounting bolts. I think there are 3 or 4 10mmm bolts.

MY husband says- Locate the bottom radiator hose, follow it back to the water pump, remove the bottom radiator hose from the water pump, making sure there is a drain pan underneathe the pump. Locate the bolts on the outside of the pump, remove bolts and pump. Clean the old gasket off of the engine. Apply gasket sealer -then the gasket-then more gasket sealer on the outside of the gasket. Apply new water pump on engine, replace bolts, making sure bolts are tightened to as close as to what they were before. Firm. Re-attach bottom radiator hose, top off fluid, and that should be it. Check for leaks after starting motor.
