im going to be replacing my head gasket probably tomorrow and i was wondering what to torque the bolts to. its an 87 mazda b2000 if that matters
make sure you go in the sequence(sp) that the service manual tells you!!! If you got a service manual..it will tell you in there what the torque specs are.
In the manual it states as follows: Cold engine(initial) 65-69 FT-lbs, warm engine (final) 69-72 ft-lbs for engines with timing chain. For engines with timing belt torque them between 59-64 ft-lbs. Hope this helps.
Your truck should have a belt. 59-64 lb/ft. Start with the middle bolt on the right then go to the middle bolt on the left, around in a clockwise fashion. Also torque them in steps, so start at 20 lb/ft and torque them all in sequence, then torque them all at 40 lb/ft, then the 59-64 lb/ft.
Make sure that the head bolts are clean, if you have engine assembly lube put a little on the treads, if not put a little automatic transmission fluid on them before you start. After the truck has been ran about 500 miles remove the valve cover and torque in sequence again at 59-64 lb/ft. If you don't do this some of the bolts will get lose due to settling and it will probably blow the gasket again in a year or two.
