They say the bolt is a non-reusable type and prone to snap if reused - are you confident it's OK to reuse? Also, mine looks to have a separate A/C belt - would you replace that tensioner too or does that one not matter?

bolt is okay to reuse on N62, however N54/N52/N55 no, one time use on those.

Do you have to replace the old tensioner bolt with new bolr?

[@clonetrooper576]

Not necessary
