Clamp the cylinder head back down to the block on your next head gasket job with the APEX Automobile Parts Inc Cylinder Head Bolt Set, part number AHB855. It is a direct-fit replacement for the listed applications: the 1998-2008 Toyota Corolla, 2000-2005 Toyota Celica, 2000-2005 Toyota MR2 Spyder, and 2003-2008 Toyota Matrix, each with the L4-1.8L engine.
Head bolts hold the cylinder head against the engine block. They supply the clamping load that compresses the head gasket so it can seal between the head and the block.
- Part type: Head bolt set for the cylinder head.
- Engine: L4-1.8L.
- Quantity per application: 1.
Signs head bolts may need replacing: stretched, corroded, or damaged bolts or threads, or a head gasket leak where lost clamping load may be a factor. Diagnose the cause of any leak before replacing parts. An engine cylinder head bolt set is also commonly installed any time the cylinder head is removed, such as during a head gasket replacement.
Consult the vehicle service information for the correct tightening sequence and torque procedure. It will also tell you whether the original head bolts may be reused.
