View Full Version : tightening of bolts----question

i'm getting ready to put the heads back in, the manual says for cylinder head bolts to tighten to 37 ft/lbs for my car, then rotate an additional 95 degrees.

after i get them to 37 ft/lbs, do i do another 95 degrees with my torque wrench at 37lbs, or put the breaker bar on and go another 95 degrees?

i can't find anywhere where it specifies and i definitely don't want to break the head off a cylinder bolt....

The measurement of 95 degrees means you should use a tool called a Torque-angle meter. Basically its just a dial that you fix into position and zero out where your breaker bar happens to be. Then you turn the head of the bolt an additional 95 degrees after the initial 37 ft/lbs.

You just use a breaker bar for this step. Yes, you can just draw lines on the bolt-heads and guestimate the angle, but using a torque-angle meter is always prefferred.

You shouldn't snap any of the headbolts if you're using new ones.
