Technical Where can I find torque specs?

[spleenharvester]

Hi all

Anyone know where I can find torque specs for a specific model/year direct from Fiat? I'm trying to find the torque settings for the topside driver side motor mount, the three nuts holding it to the subframe and the three nuts holding it to the cylinder block. I can only find forum posts with wildly varying settings from 25 Nm up to 80 Nm, I think partly because the design has changed over the years (some have bolts and some have studs like mine). I tried 60 Nm and it absolutely destroyed one of the studs, luckily one of the replaceable ones.

Is there some kind of official repair manual I can get for the 2011 312?

Thank you

If in doubt use a spanner in your hand?
Not a socket and ratchet

Or as one forum member said 3/4 uga dugas

That.

Err on the side of caution.
