I need some help determining the correct part numbers for the highlighted parts. I have checked and confirmed that I do indeed have a hydraulic belt tensioner, but I'm looking to replace the entire unit. If this is a bad idea then tell me that I just have to replace the pulley. I'm also aware that there are two different pulleys, one with a center mount and one with an offset mount. I believe that my deflection pulley is offset and my tensioner pulley is centered.
And before you tell me I need an Upper Radiator Hose and an Expansion Tank...I already have them
Over.
