To replace the water pump in a 1986 Oldsmobile Cutlass Supreme, first disconnect the battery and drain the coolant from the radiator. Remove any components obstructing access, such as the serpentine belt and the alternator, if necessary.

Reassemble all components, refill the cooling system with coolant, and check for leaks after starting the engine.
