Mahle 4879 Engine Cylinder Head Gasket

Engine Cylinder Head Gasket Overview

This Mahle engine cylinder head gasket is an OEM-standard sealing solution for heavy-duty gasoline applications. It uses a composite construction with single-sided graphite to help maintain a consistent seal under cylinder head clamping loads.

Part number 4879 is listed for Chevrolet and GMC medium-duty trucks, including Kodiak and Topkick models. Fitment notes specify cylinder head bolt replacement is recommended, and the application is for engines without LPG conversion.

Key Features

• Composite gasket construction for dependable sealing performance
• Single-sided graphite sealing surface for improved conformity
• OEM-standard item grade for service replacement use
• 0.04 in. thickness for the specified application
• Torque-to-yield fastener requirement noted in fitment data
• Part number 4879 for catalog and service matching

Detailed Application Information

Mahle 4879 is engineered for specific Chevrolet Kodiak and GMC Topkick medium-duty truck applications from 1991-1998. The gasket’s 111.00 mm cylinder bore diameter and graphite-faced sealing design support proper combustion sealing in the listed engine configurations. This part cross-references FEL-PRO 8523 PT-1 and General Motors 10101142 for the same application.

Use this gasket when servicing a compatible Chevrolet C6500 Kodiak, Chevrolet C7500 Kodiak, GMC C6500 Topkick, or GMC C7500 Topkick engine, as well as the earlier C60, C70, C6000, C7000, C5500, and C5000 applications shown in the fitment table. Part number 4879 appears in the catalog for these truck platforms and should be matched to the exact engine configuration before installation.

What This Part Helps Address

• Combustion gas leakage at the cylinder head interface
• Coolant or oil seepage caused by a worn head gasket
• Loss of compression from a compromised sealing surface
• Service issues after cylinder head removal or engine repair
• Seal failure in applications requiring torque-to-yield fasteners

Installation Notes

Follow the service manual for surface preparation, torque sequence, and torque-to-yield fastener procedures. Fitment notes call for cylinder head bolt replacement, so inspect fasteners and related sealing surfaces before assembly. Confirm the engine is the non-LPG conversion version listed for the application, and verify part number 4879 against the engine code and gasket dimensions before installation.

Quality Assurance

Mahle gaskets are trusted by OEMs and technicians worldwide for sealing applications. This gasket is built to OEM-standard specifications for the listed medium-duty truck engines.
