Please explain on a 96 cavalier 2.2 it say to torque heads 90 degress?


You are referring to the cylinder head bolt-torque sequence. Here is the instructions, then I'll clarify.

  1. Install cylinder head bolts finger-tight. New cylinder head bolts are recommended.
  2. Tighten bolts in sequence, tighten the long bolts to 46 ft. lbs. (63 Nm) plus 90 degrees. Tighten the short bolts to 43 ft. lbs. (58 Nm) plus 90 degrees.

The cylinder head is made of aluminum. Over-torque of bolts can result in warping or cracking of the head. Also, some of the head bolts go into the water jacket. Those bolts requires a teflon sealer or water will come up through the threads and result in coolant leaks. Use a thin wood dowel to probe the cylinder head bolt holes to see if they bottom out or go into the water jacket.

When you tighten the bolts, do it in the sequence directed, up to the toque specified for each length bolt. Once that has been done, you will make one more circuit of the bolts, tightening each one by 90 degrees. The easy way to do this is to place your torque wrench on a bolt with the handle pointed at 6 o'clock. Tighten the bolt another 90 degrees, or when the handle reaches 9 o'clock. 90 degrees is 1/4 revolution of the bolt. (You can start the wrench anywhere that is convenient to make the 90 degree advance without interruption.)

Hope that helps!

I need to know the torque specs for the head gasket for a 99 2.2 pontiac sunfire


Install cylinder head bolts finger-tight. New cylinder head bolts are recommended due to stretch of the old bolts.
Tighten bolts in sequence, tighten the long bolts to 46 ft. lbs. (63 Nm) plue 90 degrees. Tighten the short bolts to 43 ft. lbs. (58 Nm)


Install pushrode and rocker arms and rocker arm nuts. Tighten nuts to 22 ft. lbs. (30 Nm).


Install valve cover and tighten bolts to 89 inch lbs. (10 Nm).

Apr 16, 2010 - I have just changed the head gasket on my freelander 1.8 I followed the head bolt tightening sequence as specified in the manual (30nm then 4 turns of 90 degrees) But it just dosnt feel...


One advice, if you feel it is not tight enough then dont leave this unnoticed..give it another 15 degrees more on all bolts and even slightly more if needed. Another thing, did you level the head bit ? It is very important to have it level after a blown up gasket(I expect you must have had a blown up gasket before you change it).Hope this helps. Good luck with it.

I have a 2001 land rover discovery II and I need the torque settings so I can put the engine back togather. Im not sure how tight to tighten the head cylinder bolts or the manifold bolts.


Do not reuse the old head bolts. These are torque-to-yeild type bolts and stretch when torqued down.

Starting in the center and working your way outward:

1st step - 15 ft-lbs

2nd step - 90 degrees

3rd step - 90 degrees

For tightening head bolts on my car it says to tighten to 37 ft. lbs. then, using a torque angle meter, rotate an additional 130 degrees. why do they use ft. lbs. and degrees?why not all in ft. lbs.?


Because, by the time you twist that bolt to let's say, 65ft.lbs, it could snap.

The manufacturer of that bolt knows that if the bolt is torqued, (Stretched) to a certain torque value, and is turned a certain amount of degrees, the proper torque value will be reached, and still stay within the guidelines of the tensile strength of the bolt.

Torque is set to Bolt Stretch. How far the bolt will stretch in a given torque value, and not exceed it's tensile strength. The threads are stretched over to one side a little also, and this causes the bolt to be locked into position. They can only be 'tweaked' over to one side so many times, then they will fail.

Also the bolts have a certain tensile strength, and can only be stretched so far, and So may times.
MANY, manufacturers plainly state to not reuse a head bolt of this nature. Reasoning, is that the bolt has been stretched, and stretching it again may cause failure of the bolt.

Plus, every time the engine reaches the operating temperature, it stretches the bolts, then the bolts contract once the engine has cooled off.
[Everything you always didn't want to know, huh?]
