What Does a Car Water Pump Do?
A car water pump plays a vital role in the engine cooling system, ensuring that the engine does not overheat. It circulates coolant throughout the engine, allowing it to absorb and dissipate heat effectively. Without a functioning water pump, the engine temperature can skyrocket, leading to engine damage or even a breakdown.
The water pump is typically driven by a belt connected to the engine crankshaft, which powers its impeller. This impeller spins, creating a centrifugal force that draws the coolant from the radiator and pushes it into the engine block and cylinder heads. As the coolant passes through the engine, it absorbs excess heat and returns to the radiator, where it is cooled before being recirculated.
