To replace the water pump on a 2003 Oldsmobile Alero with a 2.2L engine, first disconnect the negative battery cable and drain the coolant. Remove the serpentine belt, then detach the timing cover and any components obstructing access to the water pump. Unbolt the old pump, clean the mounting surface, and install the new pump with a new gasket. Reassemble the components in reverse order, refill the cooling system, and check for leaks.
