- Engine: Cataloged for the H4-2.5L engine.
- Quantity per application: The listed applications use one set.
What it does: Head bolts hold the cylinder head against the engine block. They keep the head gasket clamped so it can seal the combustion chambers and the coolant and oil passages between the two.
Signs this part may need replacing: A bolt that is stretched, stripped, corroded, or otherwise damaged, or a head gasket or cylinder head job that calls for new head bolts. Diagnose the cause of any coolant or oil leak or overheating before replacing parts.
Installation note: Consult the vehicle service information for the correct tightening sequence, the torque specifications, and whether the original bolts may be reused.
