Cylinder head Bolt installation?

Hello,

2003 on 5.3 engines use 10 11mm head bolts which need to be replaced and 5 8mm head bolts which can be reused.

Tightening torque and degree:
11mm bolts, (1-10)
1st step: 22 ft/lbs
Next 2 steps you will need to use an angle gauge, see image 2
2nd step: (1-10) turn an additional 90 degrees
3rd step: (1-10) turn an additional 70 degrees

8mm bolts, (11-15)
22 ft/lbs, apply liquid Teflon paste or similar sealant to these bolts
See image 1 below for tightening sequence

Hope this helps,

Cheers, Boris
