The water pump plays a crucial role in circulating coolant (cooling fluid) 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 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 part, it will eventually fail due to age-related deterioration and mileage. As a preventative measure, it's best to replace the part when the mileage 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.
