7420734268 Water Pump for Renault Trucks DXi12 Engines

What does a water pump do?

This water pump plays a critical role in the engine cooling system by continuously circulating coolant between the engine block and the radiator. By maintaining consistent flow, it prevents overheating and ensures the engine operates within its ideal thermal range, even during high-load transport tasks.

Vehicle and engine compatibility

This component is specifically compatible with Renault Trucks Magnum vehicles, including various configurations such as the 440.26, 480.19, and DXi 12 440.18 models. It is engineered to fit Renault Trucks DXi12 engines, providing a reliable replacement for worn or leaking units in heavy commercial vehicle applications.

Installation and maintenance guidance

When performing engine maintenance, technicians should inspect the pump for signs of coolant leakage from the weep hole or unusual bearing noise. It is often recommended to replace the pump during timing belt or alternator belt service intervals to prevent unexpected failures.

Troubleshooting and longevity

Maintaining a stable temperature through a high-quality coolant pump is essential for long-term engine longevity in heavy-duty service environments.
