Where is the water pump located on a 1996 Buick Lesabre?
find radiator. follow top hose to where it enters engine. that is thermostat housing. water pump directly under it with belt-driven pulley on front of it
The water pump is on the left side of the engine bay if the repairman is standing in front of the car. The pulley for the water pump is the pulley nearly in the center of the block. The pulley is not grooved. The smooth side of the serpentine belt spins it. After removing the serpentine belt and the pulley, remove the eight bolts, four short and four long. It is also necessary to loosen the steering pump from the block since the steering pump pulley obstructs the far left bolt for the water pump.
Install in reverse order. The pulley bolts are 8mm, the smaller water pump bolts are 3/8" and the larger are 1/2".
You might also want to replace the thermostat at the same time.
The fuel filter in a 1996 leSabre is actually located under the pasengers seat close to the seat belt retratcor. It is held on by four 1/4 bolts that are a bit tricky to remove unless you have a long extansion for your socket wrench. These filters were desighned this way to make replacement eseay, but they were discontiuned there due to fire hazrds if a passenger/ driver is smoking in/near that seat.
