It is important to follow these specifications exactly to ensure proper sealing of the head gasket and to prevent damage to the engine.
Additional notes:
- Use a quality torque wrench that has been calibrated to ensure accurate measurements.
- If you are reusing the head bolts, be sure to clean them thoroughly and inspect them for any damage before reinstalling them.
- Applying a small amount of engine oil to the threads of the head bolts can help to prevent them from seizing.
- Tighten the head bolts in the correct sequence as specified in the service manual for your vehicle.
- Once the head bolts are tightened to the final torque specification, retorque them after the engine has cooled down completely.
