Hi, I have checked out the maintenance guides but can't find figures to fit the V6 clutch....
Can anyone give me the numbers for this? I just need the torque for the pressure plate to flywheel.
Thanks....

Thanks TB, I did forget one, the prop to gearbox....
On the Haynes book, I often wondered where they get their numbers from??? I work in engineering and do some testing that involves fixing torques, this includes applying a specific torque to a set of bolt, screws, nut or any combination of them, perform a test and check how the fixings are getting on.
We test move-on torque, this is always higher.
And back-off torque, this is always lower....
So, knowing this and not knowing how Haynes get their figures???

Haynes will get the info direct from GM

Oh ok, that makes sense...
Thanks for the numbers!
