Head bolts

GreenMustang00 · March 24th, 2011, 06:34 PM

I looked at the specs for the tightening of the head bolts. The final stage 3 tightening was like 37-39 foot pounds.... That can't be correct.. Anybody know the actual torque to tighten too for the head to block bolts.

This question is aimed at people who have changed their heads/head gaskets before... Not anyone else

Also on a better note I could drop my driver side long tube from the top of the engine not under

Are you sure it didn't read in-lbs?

Lol I don't think I would want to tighten them to 39 inch pounds lmao

39 ft pounds just seems too low considering the force it took to remove them

Alexander III · March 24th, 2011, 07:13 PM

I asked inches because the 4.6 is in inches as far as I remember. Obviously not 39.

Hopefully someone will chime in.

Yea 39 inch pounds is hand tight basically lmao

Every place I found listed them very close to the following:

--Step 1 15 ft/lbs
--Step 2 29 ft/lbs
--Step 3 36 ft/lbs
--Step 4 Loosen 2 full turns (from this point on, work with one bolt at a time)
--Step 5 (Long bolts) 29-37 ft/lbs
--Step 5 (Short bolts) 11-18 ft/lbs
--Step 6 Tighten additional 180 degrees

Thanks man... Just seemed too low to be true.. I suppose it has 95000 miles

mp4 player · March 24th, 2011, 10:27 PM

Just to make sure, you do know not to reuse the torque to yield head bolts right?

GreenMustang00 · March 24th, 2011, 10:32 PM

Yes I know that

GreenMustang00 · March 24th, 2011, 10:37 PM

I didn't think any of our head bolts were torque to yield anyways?

They are. That's why they have such an involved torque sequence and cannot be reused.

and probably why they are so hard to get out at only 39ft lbs :p
