Mahle 54177 Engine Cylinder Head Gasket - Right

Engine Cylinder Head Gasket Overview

This Mahle engine cylinder head gasket is built for sealing performance in applications that require an OEM-standard multi-layered steel design. It is listed for the right side and matches the fitment profile for Ford Mustang, Ford Thunderbird, and Mercury Cougar applications.

Key Features

• Multi-layered steel construction for durable cylinder head sealing.
• OEM standard item grade for a direct replacement-style service part.
• 1.12 mm thickness with a 99.31 mm cylinder bore diameter.
• No gasket sealant included.
• Torque-to-yield fastener application noted for proper installation.

Detailed Fitment and Design

Mahle 54177 is an engine cylinder head gasket engineered around a multi-layered steel sealing structure. The 54177 part number is associated with right-side applications for the 1997-1998 Ford Mustang, 1997 Ford Thunderbird, and 1997 Mercury Cougar. This part cross-references FEL-PRO 9263 PT and Ford F7ZZ 6051-AA for the same application.

As an OEM-standard gasket, it is intended for service work where consistent sealing around the cylinder bore is critical. The listed thickness and bore diameter help match the original sealing geometry, while the multi-layered steel material supports stable clamping under cylinder head load.

What This Part Helps Address

• Coolant or combustion sealing loss at the cylinder head interface.
• Compression leakage caused by a worn or damaged head gasket.
• Service replacement needs after cylinder head removal.
• Fitment issues when the original gasket no longer seals to specification.

Installation Notes and Tips

Fitment notes specify that replacement of cylinder head bolts is necessary for proper installation with this multi-layered steel gasket. Verify the cylinder bore diameter, thickness, and right-side application before assembly. Follow the vehicle service procedure for surface preparation, torque sequence, and torque-to-yield fastener replacement where required.
