85000956 Compatible Water Pump — Volvo FMX

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, responsible for circulating coolant between the engine and the radiator to prevent overheating. Built with high-strength components, it is designed to withstand the rigorous thermal and mechanical stresses typical of heavy-duty engine operation.

Compatible Volvo vehicles and engines

This part is specifically engineered for Volvo FMX models, including variants 380, 420, 460, and 500 equipped with D13K engines. It is also compatible with Volvo FM series trucks such as the FM 380, FM 420, FM 460, and FM 500. It provides reliable service for these heavy commercial vehicle applications.

Installation and maintenance

To ensure optimal performance, technicians should inspect the pump during belt replacement services. Common signs of wear include coolant leakage from the weep hole or unusual bearing noise. Maintaining the integrity of the mechanical seals and gaskets is vital for preventing system pressure loss.

Troubleshooting and selection

Proper installation ensures stable coolant flow, which protects the engine from cavitation and thermal fluctuations during intensive transport tasks.
