cylinder head bolt torque

Oct 30, 2007 1 Replies

I'm ready to bolt the head back on to my 86 Accord, but when consulting the shop manual (original shop manual from Honda) I find information that may be contradictory. On pages 6-2 and 6-16, the head bolts are referred to as 10 mm with 1.25 mm thread pitch, however I the bolts I removed are 11 mm with



1.5 mm thread pitch.

Given that the bolt size and thread are wrong in the manual, should I believe that the torque specified is correct (22 then 49 ft-lb)? I would think that the proper torque would be different for various bolt sizes and particularly for a different thread pitch.

my money says those bolts are exactly what it says in the manual and that you're using the wrong part of the caliper jaws to measure.

use book torque. use a bending beam torque wrench, not the clicky kind.
