3801102 Volvo FM and FMX Compatible 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 to prevent overheating. Built with high-strength components, it ensures consistent flow even under heavy-duty operating conditions common in construction and transport applications.

Vehicle compatibility and fitment

This specific unit is compatible with Volvo FM series engines, including models such as the FM 300, FM 340, FM 360, FM 380, FM 390, FM 400, FM 430, FM 440, and FM 480. It is also designed for fitment in Volvo FMX models like the 400, 440, and 480. Consult your authorized distributor for fitment confirmation.

Installation and maintenance guidance

To ensure proper function, technicians should inspect the pump housing and impeller during routine maintenance. If coolant leakage from the weep hole or abnormal bearing noise is detected, replacement is recommended alongside the belt service to prevent system failure.

System reliability

Maintaining a stable temperature through efficient coolant circulation is essential for the longevity of heavy commercial vehicle engines.
