Frequently Asked Questions

Q: Do I need to replace the head bolts when changing the head gasket on a 3.1L engine? A: Yes, the GM 3.1L V6 uses torque-to-yield (TTY) cylinder head bolts that permanently stretch when tightened. Reusing old bolts can lead to improper clamp load and gasket failure.

Q: Will one kit service both cylinder heads on my 3.1L V6? A: No, this kit contains one head gasket and bolts for a single cylinder head. A V6 has two cylinder heads, so you will need to purchase two kits to complete a full head gasket replacement.
