Hi there !! I will change my Volvo's 965 timing belt at 144K miles. In addition to the tensioner (damping element ($100)) and the belt . Do I need to replace the tension pulley ($89) and the idler pulley ($72)?. Please if someone can post the replacement schedule for these parts. I would like to have them on hand if I need them, rather than inspect the elements, order them and wait for them to show up.
Thanks
Arnold
