Hello everyone
Anyone can tell me what is the torque value for 12.9 bolts on a b23 engine?
What kind of bolts most people use?
Regular 12.9 bolts
Or some original bolts from others engines fitted to redblock?
Thanks

Re: Volvo b230 12.9 headbolts
I think Volvo had 110nm on the old B21:s that had 12.9 headbolts, but some people recommend 120nm for 12.9. Remember to use a harder washer as well.
And retorque them after a heat cycle.
Do you really need 12.9?
