20995158 Volvo FH Water Pump

What does a water pump do?

A water pump serves as the heart of the engine cooling system by circulating coolant between the engine and the radiator to maintain ideal operating temperatures. This component is essential for preventing overheating during high-load operations common in heavy commercial vehicles.

Compatible vehicles and engines

This specific unit is compatible with Volvo FH trucks, including various variants such as the 400, 440, 480, 500, and 520 models. It is also specifically engineered to fit Volvo FH13 units equipped with D13C engines, ensuring a precise fit for these heavy-duty powerplants.

Maintenance and installation

For optimal performance, technicians should inspect the pump during routine belt service. Monitoring for signs such as coolant leaks from the weep hole or unusual bearing noise can help prevent sudden engine overheating. Proper installation ensures long-term durability under heavy-duty service conditions.

System reliability

Selecting a high-strength component helps maintain system pressure and consistent flow rates throughout the cooling circuit.
