torque wrench settings

Hey there can someone tell me the torque wrench setting for head bolts on my EA Falcon CFI.
I have been told its 40Nm , but my torque wrench is in pounds.
And is 40Nm correct?
Thanks for any help

40 Newton Meters = 29.50 Pound Feet

No idea on the torque setting for the head bolts though. but the conversion is correct

I did put something here, but it vanshied, I think

Re: torque wrench settings

By memory it's 75 Nm.....checking....OK the book says 40 Nm then 90 dgrees tighter. huh. Never done a head like THAT before, usually I just do what it says on the packet.
Doesn't it say on the head gasket packet?

Re: torque wrench settings

A few places now are giving just a specific one off torque (ie. JMM specify a one off figure) - not sure but I think it's something like 120 ft/lb - or that could be 120 Nm - check for sure because there's a BIG difference!.

Re: torque wrench settings

The book says 40Nm then 90 degrees......odd, couldn't they just get the final figure?

Re: torque wrench settings

They don't give a final figure because the head bolts are Torque To Yield (TTY) head bolts. They are NOT supposed to be reused and basically all new cars use this type of head bolt. It gives greater clamping and the torque setting is used as a start value and the bolt is then stretched by the angle rotation past its elastic point.

Replacements cost around $30-40 a set.

Also the given settings are correct.

Re: torque wrench settings

Exactly::: It also takes away any friction between each bolt. So they are hopefully the same ..
