525.05.0004 Irisbus Compatible Water Pump

What does a water pump do?

This water pump is a critical component within 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 its required thermal parameters under heavy-duty conditions.

Vehicle and engine compatibility

This component is specifically designed for Irisbus bus models, including the Cityclass, Europolis, Access Bus II, Citelis, My Way, Recreo, Crealis, Eurorider, and Euroclass variants. It is compatible with Cursor 8 and Cursor 8 CNG engines. Additionally, this part is also fitted to Iveco vehicles.

Installation and maintenance

To ensure longevity, technicians should inspect the pump during routine belt or timing belt service. Check for common failure indicators such as coolant leaks from the weep hole or unusual bearing noise. Proper installation ensures the centrifugal pump maintains the necessary pressure for the entire cooling circuit.

Troubleshooting and inspection

Maintaining the integrity of the water pump is essential for preventing engine overheating and potential component damage in bus fleets.
