21030340 Volvo FMX D13K 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 and the radiator. By maintaining a steady flow, it prevents overheating and ensures the engine operates within its thermal limits under heavy-duty conditions.

Compatible vehicle models

This component is specifically engineered for Volvo FMX models with D13K engines, as well as Volvo FM series variants such as the FM 380, 420, 460, and 500. It is designed to meet the rigorous demands of heavy commercial vehicle operations.

Maintenance and installation

When performing cooling system maintenance, it is recommended to inspect the pump and seals during belt service intervals. Technicians should check for signs of coolant leakage or unusual bearing noise to ensure the longevity of the entire cooling circuit.

Troubleshooting and service

Regular monitoring of the cooling system helps prevent engine overheating and potential damage to other high-strength components.
