It circulates coolant through the engine and is a common replacement item on these engines where leaks or pump failure develop.

Water pumps on these engines can leak coolant from the housing, develop a failed thermostat or impeller, or trigger temperature warnings. Replacing the pump early helps prevent overheating and expensive engine damage.

Technical specifications

Installation requirements

Water pump replacement on these engines involves removing the pump drive belt cover and associated components, so workshop fitting is recommended. Use the correct coolant specification, bleed the cooling system thoroughly, and check for leaks and correct temperature regulation during a road test. Replacing the pump drive belt at the same time is good practice.

Fitment checks before ordering

Several pump revisions exist for these engines, including versions with integrated thermostat housing. Compare the part number on your existing pump and verify by engine code or VIN before purchase.
