Mahle HS54389 Engine Cylinder Head Gasket Set

Engine Cylinder Head Gasket Set

Mahle HS54389 is an OEM-standard engine cylinder head gasket set built for sealing performance in Toyota and Lexus applications. It uses multi-layer steel for the cylinder head and exhaust manifold gaskets, with a rubber-coated metal intake manifold gasket for reliable sealing across critical engine interfaces.

Compatible With 1998-2004 Toyota Land Cruiser, 1998-2003 Lexus LX470, 2000-2004 Toyota Tundra, and other listed Toyota and Lexus models. This set is a fitment-based solution for engines that require torque-to-yield fasteners and a complete gasket service approach.

Key Features

• Multi-layer steel cylinder head gasket for durable sealing under combustion pressure.
• Multi-layer steel exhaust manifold gasket for heat-resistant sealing performance.
• Rubber-coated metal intake manifold gasket for consistent manifold sealing.
• OEM-standard grade for service work that follows original equipment specifications.
• Contains miscellaneous gaskets and seals for related sealing points in the repair.
• Part number HS54389 for accurate ordering and catalog matching.

Detailed Description

Mahle HS54389 is engineered as an engine cylinder head gasket set for Toyota and Lexus trucks and SUVs covered by the fitment data, including Toyota 4Runner, Sequoia, Tundra, and Land Cruiser, plus Lexus GX470 and LX470 applications. The gasket construction focuses on sealing integrity at the cylinder head, intake manifold, and exhaust manifold interfaces, making it suitable for engine service where precise sealing is required. This part cross-references FEL-PRO HS 26226 PT and Toyota 04112-50150 for the same application. The HS54389 part number is useful when matching the correct gasket set for a repair that follows OEM-standard requirements.

What It Is Used For

• Replacing a leaking cylinder head gasket.
• Restoring sealing at the intake manifold interface.
• Addressing exhaust manifold sealing concerns.
• Supporting engine teardown and reassembly after head service.
• Servicing applications that require torque-to-yield fastener replacement.

Installation Notes and Tips

Cylinder head bolts are not included, and bolt replacement is recommended for the listed applications. Exhaust pipe gasket is not included, so verify related sealing components before beginning the repair. Confirm engine code, model year, and fitment notes before installation, especially for 2004 applications with the listed cutoff date. Follow factory torque procedures and sequence requirements for torque-to-yield fastener applications.

Quality Assurance

MAHLE gaskets are trusted by OEMs and technicians worldwide for sealing applications that require consistent fit and material quality. HS54389 is built to OEM-standard expectations for engine sealing service.
