21228793 Volvo FM FMX 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 consistent fluid flow, it prevents thermal buildup and ensures the engine operates within safe temperature parameters during heavy-duty service.

Compatible Volvo models and engines

This component is specifically designed to fit Volvo FM models (including FM 480, 440, 380, 340, 300, 400, 360, 390, 430) and Volvo FMX models equipped with D11K engines. It provides a reliable replacement for original equipment to maintain peak thermal management efficiency.

Maintenance and inspection guidance

When performing engine maintenance, it is recommended to inspect the pump and its associated seals. Technicians should check for signs of coolant leakage or bearing play during routine service intervals. Replacing the pump alongside the belt drive system can prevent unexpected downtime in fleet operations.

Operational reliability

Proper selection ensures perfect integration with existing cooling circuits, maintaining stable operating temperatures for construction machinery and heavy commercial vehicles.
