It constantly exchanges heat with the engine, maintaining the engine at the proper temperature and preventing overheating. It is mounted on the side of the engine and circulates coolant using pulleys powered by the timing belt or fan belt. When the water pump stops working, the coolant stops circulating within the water jacket, leading to a malfunction. Symptoms of a water pump failure include coolant dripping onto the ground, white deposits around the engine, rapid coolant depletion, a sweet smell from the engine compartment, the water temperature gauge showing "H" (high), and unusual noises.

While the water pump is a durable component, it will eventually fail due to age-related deterioration and mileage. The best preventative measure is to replace it when the vehicle reaches 100,000 kilometers or after 10 years. Many people opt for expensive genuine parts, but it's possible to reduce costs by using reasonably priced aftermarket parts that are compatible with the original equipment.
