Frequently Asked Questions

Q: How do I know if my head gasket is blown? A: Common signs include white exhaust smoke, unexplained coolant loss, milky oil, and persistent overheating. A compression tester or chemical block-test kit confirms the diagnosis.

Q: Are the cylinder head bolts required for this repair? A: Yes, GM 4.8L and 5.3L engines use torque-to-yield head bolts that permanently stretch during installation. Always replace them; this kit includes the correct new bolts.
