This is telling you to go to the torque setting on your wrench of 22 pounds & stop. Next you need to coninue toturn the bolt with your wrench a measurement equal to 55 degrees.

Remember that 90 degrees is a 1/4 right or left turn so adding 55 degrees should be somewhere just a little past 1/8 of a right turn after you have reached the 22 pounds. good luck

    Just so there is no confusion: 55 degrees is just a bit more than 1/8 of a turn and considerably less than 1/4 turn. Turning past 1/4 turn when only required to turn 55 degrees could damage the Yeild to torque headbolts or the sealing surface, by overtigtening. Use caution.



    360 degrees = 1 full circle

    180 degrees = 1/2 circle

    90 degrees = 1/4 circle

    45 degrees = 1/8 circle.

I know...screwy way of doing it but what you do is torque to the specification then turn the wrench 55 degrees more (hint : 1/4 turn is 45degrees, half turn is 90 degrees, one full turn is 360 degrees etc) So on your example you would torque to 22lbs then turn it a bit more than a quarter turn past where you stopped at 22 lbs.

Chevy trailblazer 4.2 6 cylinder head bolt torque in ft/lbs only and sequence


the sequence can be found online @ fel-pro torque table they are now using angle meteres because these bolts are tty (torque to yield ) which means they are designed to stretch, I recommend using new head bolts, and the final ft./lbs will be 55lbs they tighten in three stages ,follow the directions in torque table, do not use air ratchet on initial tightening , I have been using anerobic sealant on headbolts as some now go into aluminum threads and water jackets. hope it helps

I have a 1998 chevrolet pickup .i need to know the head bolts torque specifications for a 350 so i can put the heads back on it


There is a sequence of tightening the head bolts in a specific order in 2 passes, the preferred method is to tighten all bolts to 22 ft lbs, then add 75 degrees turn to long bolts, 65 degrees to medium bolts, and 55 degrees to short bolts. If you need the picture go to a library and use alldata to print it out.
