Head Bolt Re-Usability

INSPECT CYLINDER HEAD BOLTS






Using vernier calipers, measure the thread outside diameter of the bolt.
Standard outside diameter: 9.810 - 9.960 mm (0.3862 - 0.3921 inch)
Minimum outside diameter: 9.700 mm (0.3819 inch)

If the diameter is less than the minimum, replace the bolt.
