20920065 Volvo FMX D13K Engine Water Pump

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 block and the radiator. By maintaining consistent fluid flow, it prevents overheating and ensures the engine operates within its designed thermal parameters even under heavy loads.

Compatible Volvo models and engines

This component is specifically compatible with Volvo FMX models featuring D13K engines, including variants such as the 380, 420, 460, and 500. It is also fitted to various Volvo FM series trucks such as the FM 360, FM 380, FM 400, FM 420, FM 440, FM 460, FM 480, and FM 500 models.

Installation and maintenance

When performing routine maintenance, it is recommended to inspect the water pump alongside the belt and pulley assembly. Technicians should check for signs of coolant leakage from the weep hole or unusual bearing noise to prevent unexpected engine downtime. Proper installation ensures long-term reliability in heavy commercial vehicle applications.

Troubleshooting guidance

Selecting a high-strength component helps prevent cavitation and erosion of the impeller, maintaining stable flow rates throughout the service life of the engine.
