85000957 Volvo FH D11K Water Pump

This water pump serves as a vital component within the engine cooling system, facilitating the continuous circulation of coolant between the engine block and the radiator. By maintaining consistent flow, it prevents overheating and ensures the thermal stability required for heavy commercial vehicle engines during intensive service cycles.

This unit is specifically engineered for Volvo FH (FH4/FH5) models equipped with D11K engines, including various variants such as the 400, 420, 440, 460, 480, 500, 520, and 540 series. It provides a reliable solution for maintaining engine temperature across these heavy-duty applications.

For optimal performance, technicians should inspect the pump and its drive belts during routine maintenance intervals. If coolant leakage or unusual mechanical noise is detected near the pump housing, replacement is recommended to prevent system failure. Always verify engine compatibility before installation.

Check the compatibility list.
