A water pump replacement is needed when the water pump stops circulating or is leaking coolant. The water pump is a mechanical device attached to the engine that forces liquid coolant through the hoses, passageways, and radiators to move heat in the system. In most engines, a belt connects the pump and the crankshaft, transferring rotational power. Water pump failure can lead to overheating, leading to engine failure, so when a water pump goes bad, it must be repaired or replaced.
