Detailed Product Overview

Mahle 54442 is a multi-layered steel head gasket designed for engines that require stable sealing across the combustion chamber, coolant passages, and oil passages. The MLS design helps maintain clamp load consistency when paired with the correct torque sequence and replacement cylinder head bolts. This part cross-references FEL-PRO 1160L and 1160R for the same application.

Compatible vehicle coverage includes 2005-2013 Chevrolet Silverado 1500, 2005-2013 GMC Sierra 1500, 1997-2004 Chevrolet Corvette, 1998-2002 Chevrolet Camaro, and 1998-2002 Pontiac Firebird. It also serves many other GM-platform applications across the 1997-2017 model years.

What It Helps Fix

• Combustion gas leakage past the cylinder head
• Coolant loss caused by head gasket sealing failure
• Oil and coolant cross-contamination
• Compression loss from a compromised head seal
• Overheating related to gasket failure

Installation Notes and Tips

Use this gasket with clean, flat mating surfaces and follow the factory torque procedure exactly. Because this application uses torque-to-yield fasteners, replace the cylinder head bolts during service and verify head and block condition before assembly. Confirm bore size, thickness, and engine code before installation on Chevrolet Express, GMC Savana, and other listed applications.
