85000957 Volvo FM D11A Water Pump

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, driving the circulation of coolant to prevent overheating. It is manufactured using high-strength components designed to withstand the rigorous thermal and mechanical stresses encountered in heavy commercial vehicle applications.

Compatible vehicles and engines

The unit is specifically designed for Volvo FM series trucks, including models such as the FM 360, FM 380, FM 400, FM 420, FM 440, FM 460, FM 480, and FM 500. Additionally, it is compatible with Volvo FM11 trucks featuring the D11A engine. For exact fitment, verifying your engine code is recommended.

Installation and maintenance

To ensure maximum service life, technicians should inspect the water pump during every coolant flush. It is essential to check for any signs of leakage around the seals and to ensure that the drive belt tension is within manufacturer specifications. Proper maintenance prevents premature wear of the internal impeller and housing.

Selection guidance

Selecting a high-quality replacement ensures consistent cooling performance and protects the engine from thermal fatigue. Consult your authorized distributor.
