Have questions reqarding replacing head gasket on a '97 2500 with a 5.9. Two thicknesses of gasket are offered? Which one? Also does anyone out there have the torque specs for this job?

 

Get the thicker gasket it lowers the compresion a little but not enough to tell. Tourqe # are Step 1 all bolts to 66 ft lbs, step 2 long bolts 89 ft lbs, step 3 all bolts turn an additional 90- degrees, per Haynes Manual.

 

should I replace head bolts or not?

 

It would be a good idea to get new ones or at least check the old ones to make sure they havent stretched.

 

Always replace the head bolts. Also when you torque the head start in the center and work out. Front to back.Center front, center back.

There is a procedure to use.

ok thanks for the info
