Torque specs for opel corsa 1.4 comfort utility 2005 model


Assume you are needing the cylinder head torque specs?

The head bolts are angular torqued and best practice is to fit new bolts and ensure all the female threads are thoroughly cleaned. I recommend greasing the bolt threads and washer faces.

The initial torque (following a spiral pattern) is 25 NM followed by angular movements of (degrees) 90 + 90 + 90 + 45
I generally start the engine and thoroughly warm up and allow it to cool before the final 45.

I need to know torque specs and torque pattern for a 2001 head gasket on my 2001 sunfire


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.

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 blew the head gasket on my 2002 Chevy Cavalier 2.2 L OHV. I am needing to know the torque specs so that I can have the gasket replaced tomorrow! A picture would be wonderful! Uncle is going to fix it but...


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:df03f54.gif 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:
e8f4606.gif 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.
