Detailed Description

WH497P is engineered as a standard replacement piston for engine block service where bore size, compression height, and ring groove dimensions must match the original build specification. The hypereutectic construction supports consistent performance in modern engines, while the flat head profile and 9.2:1 compression ratio align with the listed Ford Ranger, Ford Taurus, Ford Aerostar, Ford Windstar, Ford Probe, Mercury Sable, Mercury Topaz, and Mazda B3000 applications. Sealed Power uses advanced materials and ISO/QS-certified manufacturing practices to produce parts that meet demanding engine rebuild standards. This part cross-references Hepu P1575 for the same application.

What This Piston Helps Address

• Worn or damaged piston surfaces during engine overhaul
• Compression loss caused by piston wear or mismatch
• Incorrect bore or compression height during rebuild work
• Ring seal issues tied to out-of-spec piston dimensions
• Restoration work on Ford Ranger, Ford Taurus, and Mazda B3000 engines

Installation Notes and Tips

Verify bore size, compression distance, pin diameter, and ring groove widths before assembly. WH497P is a standard-size piston, so cylinder measurements should be checked carefully during machine work. Confirm the correct ring set for the application, including the noted WE-446K or WE-446X ring set where specified for certain fitments. Follow factory service procedures for clearance checks, ring end gap, and piston orientation during installation.
