85023490 Volvo FMX D13K Water Pump

What does a water pump do?

This water pump serves as a vital component within the engine cooling system, responsible for circulating coolant between the engine and the radiator. By maintaining consistent fluid flow, it prevents engine overheating and ensures thermal stability during heavy-duty operation. This component is manufactured using high-strength components to withstand rigorous thermal cycling and mechanical stress.

Vehicle compatibility and engine fitment

This part is specifically compatible with Volvo FMX models, including variants 380, 420, 460, and 500 equipped with D13K engines. It is also fitted to Volvo FM trucks, specifically the FM 380, FM 420, FM 460, and FM 500 models.

Installation and maintenance guidance

To ensure optimal performance, workshop technicians should inspect the pump during routine belt services. Common indicators for replacement include coolant leakage from the weep hole or unusual noise from the bearing assembly. Regular checks of the mechanical seal and gaskets are recommended to prevent system pressure loss.

Troubleshooting and replacement

Maintaining the integrity of the water pump helps protect the entire cooling loop, including the thermostat and radiator.
