Even after you get the instructions which are not too hard, when putting back the belt, you will need to tweek the upper cams to get the right pressure or it will end up lose. This means that you will have to be patient and play with the cams to get it right. You will need two people, though I did it alone, it is easier with two people, one to hold the belt and one to hold one of the cams wit 17mm wrenches. Oh, time to think about replacing your fan with a Pep-Boys electric fan, it's easy and you won't be sorry you did, more horse power a more cooling as well and better heating considering you can turn it off during the winter.
