I need head bolt torque specs


Hello, you will start from middle head bolts and work out to end bolts. Use a crisscross pattern. Set all bolts at 20 ft pounds then repeat to a final setting of 51 -54 ft pounds. Just be sure you do an "x" patern from middle bolts working out. Also be sure you coat th threads of each headbolt with some oil so they torque smooth and accurate.

Hi im a mechanic... I have a 2000 Deville with a northstar. Radiator, waterpump, thermostat, are all changed and good. There are no external leaks. I heard the Northstar motors have problems with there...


What happens is the head gaskets shrink causing the headbolts to loose torgue, and the headbolts are of one time use, whenever you do a headgasket job you will need to replace all the headbolts with new ones. and when ever you remove a cylinder head on any engine you should always chase the bolt holes with the proper tap, then blow out the holes with compressed air, this will help to insure a more accurate torque setting on the new headbolts...

It is the best auto technician database available today. You can print out specific troubleshooting procedures, diagrams, step-by-step istructions, and soforth. The typical person cannot afford to pay for this service, just automotive dealerships, etc... that is why the public library made it available to everyone and for free to view and print out material.

Replacing head


There should be 10 headbolts. This vehicle uses torque to yield headbolts and should be replaced with the new gasket. Bolts 1-8 get torqued to 40 ft lbs initially, bolts 9 and 10 get torqued to 30 ft lbs initially, Then all bolts get turned an additional 90 degrees. I would strongly suggest borrowing a torque angle gauge for doing this or you might be doing the same repair next week.
