torque to yield bolts only good for one use. torque pattern will always be from the inside out working in a circle pattern replace the head bolts ask your parts guy the torque yield spec.

what does meaning tata bus bolt tighten "mkg"

HINT: The "torque pattern" on ALL cylinder heads is start in the center and work your way toward the ends. The specifications below are "torque-to yield" or "torque angle" specs. When in doubt, about 65 Ft. Lbs. will work on pretty much ANY aluminum head. The main point is to get them EVEN to prevent warpage.

Fig. 13: Cylinder head bolt torque sequence for 2.2L engines

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) plue 90 degrees.

Hope helps.

i hope that makes sense and helps.

When torquing items today very little is done with just "numbers" in the process. Now you have to have an angle meter to complete the process so when you see me say to torque a specific number "plus so many degrees", this is how it's done. This is the meter: Now, Here are the specs for installing the head:
Cylinder Head Bolt

• First Pass

30 N·m
22 lb ft

• Final Pass

155 degrees


Here is the sequence shown in picture form:
Also, you will need to discard the old bolts because they are "torque to yeild" bolts and CANNOT be reused. The reason: "Torque to yeild" bolts actually stretch during the torque process and once they've gone through this process they can't be reused because they no longer are able to "clamp" the head because they are too long. Hope this helps your repair project.
