HEAD BOLT TORQUE For your 1999 PONTIAC GRAND AM: HEAD BOLT TORQUE FOOT POUNDS (FINAL TORQUE) TORQUE SEQUENCE --------- | 6 2 3 7 | | 5 1 4 8 | --------- STEP 1: TORQUE IN SEQUENCE TO 33 FT/LBS STEP 2: TURN AN ADDITIONAL 90 DEGREES RECHECK FINAL TORQUE IN SEQUENCE *** CAUTION *** ENGINE USES TORQUE TO YIELD HEAD BOLTS (TTY) THAT PERMANENTLY STRETCH DURING THE INITIAL INSTALLATION. NEW HEAD BOLTS MUST BE USED WHEN CYLINDER HEAD IS REPLACED OR RE-INSTALLED TO OBTAIN PROPER TORQUE. ALWAYS COAT BOLT THREADS WITH THE PROPER SEALANT.

Get a manual on your car from the parts store. It will help on the next repair. They are about $18

There is a special sequence to torque the bolts properly. I would suggest you check in either a factory service manual, a Chilton manual or a Haynes manual to get the proper sequence plus the pattern. There is no way to post the pattern here.

It is important to know the head bolt tightening sequence and the torque of a vehicle. For the Fiat Punto it is 20nm, 30nm, 90 degree turn, 90 degree turn, then in order 8,6,2,5,10,7,3,1,4,9.

For the 1996 Saturn SL1 1.9 liter 4-cylinder, the torque in sequence one is 22 ft/lbs. In step two, torque in sequence to 37 ft/lbs. In step three, turn all the bolts 90 degrees and double check the final torque in the sequence.

The head bolt torque specs of a 1985 3.8 Ford Ltd. is 50 to 55 ft lbs. This 65 to 71 Nm belongs to a 6-cylinder torque sequence engine.

A 1993 Pontiac Sunbird head bolt torque sequence recommends starting at one and of the head and alternating to the other end of the head. You should end up in the middle.

Experience. ----------------- If the bolt is horizontal : With weights, you can take a wrench of known length and knowing the torque needed, calculate the amount of weight needed to apply the proper torque to the wrench when it is horizontal. Otherwise you can only guess at it.

The cylinder head bolt torque specs for a Mitsubishi 2.0 or 2.6 is 65 to 72 ft. lbs. cold. Torque sequence is as follows.

User Avatar

To do this, you will use a torque-wrench. You don't usually torque a bolt to the present specifications, but you get the proper specification numbers out of a service manual. There is information on-line that will tell you the proper torque specifications of pretty much every bolt and nut in a vehicle. Google is your friend.

first torque them in sequence to 29 ft lbs, then to 51 ft lbs, then to 72 ft lbs.
