I decided to take on what I thought would be the simple task of changing the serpentine belt on my truck (98. 5) without a service manual. Well now the belt tensioner has moved like 5 inches and I cannot get it back into position so I can slip the belt onto the pullies. There has got to be a simple way to do this. I am using a crow bar and pulling on it like mad and I can't get it back into position. Help!
