How do you change a water pump on a Chevy Cavalier?

To change a water pump on a Chevy Cavalier, first, disconnect the negative battery terminal and drain the coolant. Remove the drive belt and any components obstructing access to the water pump, such as the alternator or timing cover if applicable. Unbolt the old water pump, clean the mounting surface, and install the new pump with a new gasket or sealant. Finally, reassemble all components, refill the coolant, and reconnect the battery.
