EricF Posted December 4, 2004 Report Share Posted December 4, 2004 I can't find my Haynes manual, so I was just wondering what the torque figures are for the 850 head bolts... And are they TTY bolts? I hope not :ph34r: Link to comment Share on other sites More sharing options...

Bay13 Posted December 4, 2004 Report Share Posted December 4, 2004 It's a three torque process, from the center out each time, with the bolts having the threads dunked in oil first.1st is 20nm (14LbFt.)2nd is 60nm(44LbFt.)3rd is 130degrees.

EricF Posted December 4, 2004 Author Report Share Posted December 4, 2004 Thanks Are the head bolts re-useable or are they torque to yield bolts?Hope they're re-useable... Link to comment Share on other sites More sharing options...
Bay13 Posted December 4, 2004 Report Share Posted December 4, 2004 They can be reused. If you had the Volvo manual, it lists a length the bolts can be before you have to get new ones. I've found over time re-used once is OK, the second time around you are better off getting new head bolts cause they are close to being too long.
