7421814009 Renault Trucks Kerax DXi11 Water Pump

This water pump is a critical component of 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 safe thermal limits during heavy-duty service.

This component is engineered to fit Renault Trucks Kerax models equipped with DXi11 engines, as well as Renault Trucks K series including the 520T MEDIUM, 520T HEAVY, 520P MEDIUM, 520P HEAVY, K520, K440, and K480 models. It serves as an OE-equivalent solution for these specific heavy commercial vehicle applications.

To ensure reliable performance, technicians should inspect the pump during routine belt or timing belt service. Common signs of wear include coolant leakage from the weep hole or unusual bearing noise. Replacing this unit helps prevent catastrophic engine overheating and maintains system integrity.
