Cylinderhead torque settings


I'm not sure what engine you have in your 95 grand am SO I will give you both the 4cyl and 6cyl Specs. Also you didn't ask for the torque sequence. I will include that as well for both. 2.3 DOHC Quad 4cyl: Torque sequence---> front ' 7 3 1 5 9 ' of engine ' 8 6 2 4 10 ' Step 1: torque bolts 1 thru 6 (26 Ft/Lbs & 90 degree turn) Step 2: torque bolts 7 & 8 (15 Ft/Lbs & 90 degree turn) Step 3: torque bolts 9 & 10 (22 Ft/Lbs & 90 degree turn) Recheck final torque in sequence *** CAUTION *** This engine uses "Torque To Yield" (TTY) head bolts that means they permanently stretch during the initial installation. New head bolts must be used when cylinder head is replaced or re-installed in order to obtain proper torque. 3.1 liter V6 Torque sequence--> ' 6 2 3 7 ' ' 5 1 4 8 ' Step 1: torque bolts in sequence to 33 Ft/Lbs Step 2: turn an additional 90 degrees Recheck final torque in sequence *** CAUTION *** This particular engine uses "Torque To Yield" head bolts(TTY) (that means the bolts permanently stretch during the initial installation.) You MUST use NEW head bolts when replacing or reinstalling the cylinder head in order to obtain the proper torque.

4.3 v6 head gasket torque schematic


first round is at 22lbs, second 44lbs, third 66lbs. make sure you get the order in which the bolts need to be tightened as not to warp the cylinder head, and that sequence is in the package your new head gasket (s) came in. If you cant find it, your local garage will photocopy it for you.

I have a pontiac and i keep blowing head gasket on number one cylinder. I have installed new heads and gasket lasted about five years. I was wondering what the correct head bolt torque is for a 1995...


cylinder head bolts, step one;33 ft. lbs, second step rotate an additional 90-degrees (1/4 turn). do not put any oil or sealant on gasket. the gasket should seal itself if torqued properly.
