What Is the Water Pump in a Car?

The water pump is an essential component of a car’s cooling system. It is responsible for circulating coolant throughout the engine to keep it at an optimal temperature, preventing overheating. In the United Kingdom, where the climate can vary greatly, a functioning water pump is crucial for the longevity and performance of a vehicle.

The water pump is usually located at the front of the engine, driven by a belt connected to the engine’s crankshaft. Its main purpose is to circulate coolant from the radiator to the engine and back, ensuring a consistent temperature throughout. This process prevents the engine from becoming too hot, which can lead to severe damage or even engine failure.
