7421814040 Renault Trucks Kerax DXi11 Water Pump

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, responsible for the continuous circulation of coolant between the engine block, cylinder head, and radiator. By maintaining consistent fluid flow, it prevents overheating and ensures the thermal stability required for heavy commercial vehicle engines under demanding operational loads.

Compatible Renault Trucks models

This specific part is engineered for Renault Trucks Kerax models featuring DXi11 engines, as well as various Renault Trucks K series configurations including K440, K480, K520, and specific 520T variants. It is also compatible with a wide range of Renault Trucks Kerax models such as the 480.32 and 520.33 series.

Installation and maintenance

For workshop technicians, it is recommended to inspect the pump housing and mechanical seals during routine cooling system service. When replacing this component, ensure the mounting surfaces are clean and check the condition of the drive belts to maintain system integrity. Proper installation is vital to prevent leaks or bearing play in the cooling circuit.

System reliability

Maintaining a high-performance cooling system requires high-strength components that can withstand constant thermal cycling and pressure changes within the engine block.
