20995158 Volvo FM Compatible Water Pump

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 steady flow, it prevents engine overheating and ensures stable thermal management during heavy-duty operation. The unit is constructed from high-strength components to withstand rigorous thermal cycles and mechanical stress.

This specific part is designed for Volvo FM series trucks, including the FM II and FM III generations. It is compatible with a wide range of models such as the FM 400, FM 360, FM 340, FM 380, FM 440, FM 480, FM 300, FM 390, and FM 430. Additionally, it provides fitment for Volvo FM III variants including the 500 LNG, 420 LNG, and 460 LNG models.

For optimal performance, workshop technicians should inspect the pump during belt service intervals. Common indicators for replacement include coolant leakage from the weep hole or unusual bearing noise.
