Detailed Description

Mahle HS54425 is an OEM-standard engine cylinder head gasket set engineered for Nissan engines that require dependable sealing at the cylinder head, intake manifold, and exhaust manifold interfaces. The multi-layered steel construction at the head and exhaust manifold helps maintain sealing under heat and combustion pressure, while the molded rubber intake manifold gasket supports a stable intake seal. Mahle gasket technology is widely used by OEMs and technicians for engine repair work where accurate fit and consistent sealing matter.

This part cross-references FEL-PRO HS 26239 PT-1 for the same application.

What It Helps Address

• Coolant loss from a failed cylinder head gasket seal
• Compression leakage between the cylinder head and engine block
• Exhaust leaks at the manifold sealing surface
• Intake manifold vacuum leaks caused by worn sealing components
• Oil seepage from aging engine gaskets and seals

Installation Notes and Tips

Confirm engine code and application details before installation. Cylinder head bolts are not included, and replacement is recommended on torque-to-yield applications. Exhaust pipe to manifold gasket is not included for the listed Nissan Quest, Maxima, Murano, and Altima applications. Clean all mating surfaces thoroughly and follow the factory torque sequence and specifications during assembly.
