85003125 Volvo FH Water Pump

What does a water pump do?

A water pump plays a critical role in the engine cooling system by circulating coolant between the engine and the radiator. This ensures the engine maintains its ideal operating temperature even under high loads. This replacement water pump is engineered with high-strength components to withstand the demanding conditions of heavy commercial vehicle operation.

Compatible Volvo vehicles and engines

This component is compatible with Volvo FH models including the 400, 440, 480, 500, and 520 variants, as well as Volvo FH13 engines featuring the D13A engine code. It serves as a reliable replacement to maintain thermal stability during long-haul transport or intensive construction tasks.

Installation and maintenance

For optimal performance, technicians should inspect the pump and its drive belt during every cooling system service. Signs of wear such as coolant leakage from the weep hole or unusual bearing noise indicate that a replacement is necessary to prevent engine overheating.

Troubleshooting and selection

Maintaining a consistent coolant flow is vital for protecting engine longevity. Consult your authorized distributor to verify exact fitment for your specific engine configuration.
