05 grand cherokee seized tensioner
So I took my 05 grand cherokee (3.7L) into the shop to replace the starter. I was told that my serpentine belt tensioner was seized and needs to be replaced. How easy is it to replace this item? I have looked on the internet but have not found how to do so. Do I have to replace just the pulley or the whole tensioner. Any help would be great. Was also told that the throttle body needs cleaned, is this really necessary.
