The car water pump is a crucial component of a vehicle's cooling system. It circulates coolant from the radiator to the engine, ensuring that the engine remains at an optimal temperature. Typically driven by the engine's crankshaft via a belt, the water pump consists of a housing, impeller, and a bearing. Proper functioning of the water pump is essential to prevent engine overheating, which can lead to severe damage. Regular maintenance, including checking for leaks and ensuring the coolant level is adequate, helps in prolonging the life of the water pump and the engine.
