Hey All, I would really appreciate you help. I am replacing my belt tensioner for my S60 2011 but the part has been decontinued twice and now apperently a new mount must be put on the engine block in order to use the current belt tensioner. I there a specification on how to do that. Volvo seem to be quite tight lipped on how the proceedure is. Thanks for you help. Also if anyone has the old belt tensioner I would much rather have that. The part number is 3136674. Thanks
