Im wondering if any of you fine folks have replaced your belt tensioner on a 4.7L? I picked up the tensioner but havent had time to get it in. Im wondering if theres anything i may need to know before i tackle this? Ive done this on my old sierra and it was a quick and easy swap. On the D it looks like it may be a PITA being that there isnt much room down there. Thanks in advance and keep up the good work everyone.
