How do you change a water pump on a Renault espace 1995?

To change the water pump on a 1995 Renault Espace, first ensure the engine is cool, then disconnect the battery. Drain the coolant and remove the drive belt, followed by the timing belt if necessary, as the water pump is often located behind it. Unbolt the water pump and clean the mating surfaces before installing the new pump with a new gasket. Reassemble in reverse order, refill the coolant, and reconnect the battery.
