What it does
Many modern engines use torque-to-yield head bolts that stretch when tightened, so they should not be reused. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.
Installation & tips
- Clean the threads in the block, follow the torque sequence and angle steps for your engine, and do not reuse stretch bolts.
- Head gasket: Bolts and gasket go on together.
- Thread chaser: Clean block threads give accurate torque.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
