Detailed Product Description

The Mahle HS54173A gasket set is engineered to meet OEM standards, providing a reliable sealing solution for Toyota 4Runner, T100, and Tacoma engines. The cylinder head gasket is made from graphite, offering excellent heat resistance and sealing capabilities under high pressure. Included steel gaskets for the exhaust and intake manifolds ensure durability and proper sealing against exhaust gases and intake air leaks. The set also contains camshaft seals, distributor gaskets, valve stem seals, and timing cover gaskets, covering multiple sealing points critical to engine operation. Four fuel injector O-rings are included to maintain fuel system integrity. This gasket set does not include cylinder head bolts or head fasteners, so those must be sourced separately.

Compatible Applications and Common Repairs

• Replacement of worn or damaged cylinder head gaskets on Toyota 4Runner, T100, and Tacoma
• Repair of exhaust manifold leaks with included steel gasket
• Sealing intake manifold leaks using steel intake and upper plenum gaskets
• Addressing oil leaks around camshaft and valve covers

Installation Notes and Tips

Ensure all mating surfaces are clean and free of debris before installation. Follow manufacturer torque specifications, especially for the torque to yield cylinder head gasket. Since cylinder head bolts and head fasteners are not included, verify the condition of existing hardware and replace if necessary. Proper installation of camshaft seals and valve stem seals is critical to prevent oil leaks. Use appropriate lubricants on O-rings during installation to avoid damage.
