CRV 2.2 diesel tensioner pulley

[Johnnyboy]

Hi all, I'm new on here. I need to change the tensioner pulley on our CRV 2.2 CDTi. The centre bolt is very tight and I'm worried about stripping the thread. Does anyone know if its a left hand thread? 

Thank you in advance.

They are usually very tight indeed and should be right hand thread, it would only really be left hand thread if the pulley was rotating in the opposite direction to the bolt thread in which case it could unwind the bolt.
Maybe use a small amount of studlock or nutlock when refitting to ensure it stays in place
