The water pump plays a crucial role in circulating coolant (cooling water) to cool the engine, which becomes hot due to combustion. 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 the coolant using pulleys powered by the timing belt or fan belt.

If the water pump stops working, coolant will no longer circulate within the water jacket, leading to engine failure. Symptoms of a water pump failure include coolant dripping onto the ground, white deposits around the engine, rapid coolant depletion, a sweet smell coming from the engine compartment, the water temperature gauge showing "H" (high), and unusual noises.

Damage to the impeller (blades) due to aging is also a common problem. While water pumps are durable parts, they will eventually fail due to aging and mileage. The best preventative measure is to replace it when the mileage reaches 100,000 km 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.
