Detailed Product Description

Mahle HS54559D is an engine cylinder head gasket set engineered for Jaguar X-Type and Jaguar S-Type fitments listed below. The set uses multi-layer steel for the head gasket, perforated steel for the exhaust manifold gasket, and molded rubber for the intake manifold gasket, giving the assembly the material mix needed for high-temperature sealing areas. The HS54559D part number identifies this specific gasket set for service work where accurate sealing and correct component matching matter.

MAHLE gaskets are trusted by OEMs and technicians worldwide for sealing applications, and this set follows that same OEM-standard approach. This part cross-references FEL-PRO HS 26248 PT-1 and Jaguar JLM20680 for the same application.

What This Part Is Used For

• Replacing a leaking cylinder head gasket
• Restoring sealing at the intake manifold interface
• Addressing exhaust manifold gasket leakage
• Repairing coolant or combustion sealing loss at the head
• Supporting engine service after head removal

Installation Notes and Tips

Fitment includes 2002-2007 Jaguar X-Type and 2001-2002 Jaguar S-Type applications, with notes indicating cylinder head bolts are not included and replacement is recommended. Because this is a torque-to-yield application, follow the factory tightening sequence and torque procedure exactly. Verify engine code, chassis breakpoints, and all sealing surfaces before assembly. The HS54559D should be installed with clean, flat mating surfaces for proper sealing.

Quality Assurance

Mahle manufactures sealing products used by OEMs and professional technicians, and this gasket set is built to OEM-standard expectations for engine service.
