What Is A Water Pump On A Car?


Vehicle Water Pump | Lou's Car Care Center, Inc.


One of the most critical components of your car is the water pump. But what exactly is a water pump, and why is it so essential for your car?  

A water pump circulates coolant throughout the engine and transfers heat from the engine to the radiator. It maintains a consistent temperature throughout the engine. A water pump consists of a rotor, a housing, and an impeller. The rotor is connected to the engine's crankshaft via a belt. It rotates the impeller inside the housing, which pumps coolant through the engine.

Due to a lot of mechanical wear and tear, water pumps tend to fail over time. The most common sign of a failing water pump is visible coolant leakage underneath your car. If you notice a leak, you should get your car inspected immediately by a professional mechanic. A failing water pump can cause the engine to overheat. And may cause severe damage to your vehicle.

Replacing a water pump is a relatively simple process for a professional mechanic. It typically takes a few hours depending on the make and model of your car. Have your water pump inspected regularly to avoid any severe damage to your engine.

Not every pump is created equal. Selecting a high-quality water pump from a reliable source ensures its longevity and reliability. Be sure to select a water pump that's compatible with your car's make and model. And find a water pump that meets or exceeds OEM standards.
