Detailed Description

Metelli PA903 is engineered as an OE-style engine water pump for vehicles that rely on consistent coolant flow to maintain operating temperature. The metal impeller measures 66.8 mm outside diameter and uses six vanes to move coolant through the engine and radiator circuit. The aluminum housing supports corrosion resistance and stable fitment, while the roller/ball bearing construction helps the pump shaft run smoothly under normal engine loads. PA903 is a practical choice for cooling system repair on Ford Focus, Ford Fusion, Mazda 3, Mazda 6, and related platforms.

This part cross-references Gates 22251 for the same application.
