Frequently Asked Questions
Do I need new bolts with a head gasket?
If the old bolts are stretched or you want a known baseline, fit a fresh set and torque to the correct sequence.
How do I know I need fresh head bolts?
If you are pulling the head and the bolts are torque-to-yield or show any stretch or thread damage, fit a fresh set. Even clamping load is what makes the head gasket seal.
Should I replace this if it is not leaking yet?
If you already have the area apart for other work, fit a fresh one while the labor is done. Otherwise replace it once it weeps.
