Detailed Description

Mahle HS54356B is built for engine repair work where reliable sealing is critical after cylinder head service. The set is specified with a graphite cylinder head gasket, multi-layered steel exhaust manifold gasket material, and molded rubber intake manifold gasket material, giving technicians the core sealing components needed for a complete top-end reseal. This part cross-references FEL-PRO (e.g., HS 26150 PT-2, HS 26150 PT-3) for the same application.

For Cadillac DeVille, Cadillac Seville, Cadillac Eldorado, and Pontiac Bonneville applications, HS54356B supports a direct-fit sealing service when the engine is being opened for head work. The part number HS54356B is also useful when matching an OEM-standard gasket set for these vehicles.

What This Part Helps Address

• Coolant or compression loss at the cylinder head sealing surface
• Intake manifold sealing issues during engine reassembly
• Exhaust manifold leakage at the gasket interface
• Multiple sealing points that are serviced together in a top-end repair
• Repeat teardown caused by worn or damaged engine gaskets

Installation Notes and Tips

Fitment notes indicate cylinder head bolts are not included, the water pump mounting gasket is not included, and cylinder head bolt replacement is recommended. Because this is a torque-to-yield application, follow the vehicle service procedure and torque sequence exactly. Verify all sealing surfaces are clean and flat before installation.

Quality Assurance

MAHLE gaskets are trusted by OEMs and technicians worldwide for sealing performance. HS54356B is an OEM-standard gasket set designed for professional engine service on the listed Cadillac and Pontiac applications.
