I have a 99 Explorer that has an awful squeek coming from the belt. Its a 4.0
ohc with a/c. At first I just thought that the tensioner was bad so I
replaced it. Then it was still doing it so I put another belt on it to hope
solve the problem. Didnt work. The last thing I did was put a new alternator
on it because I thought maybe the bearing inside was bad. After doing all
this and racking my brain for the past six months I finally figured out what
the problem was, the tensioner even with a brand new belt on it is not having
enough tension on it. On the top of the tensioner it shows the travel of the
tensioner, and there is none. Does anyone know any other way to adjust the
tension on this model whether it be any of the other pulleys or a different
belt from a different model. I have read alot of the entries on this website
dating all the way back to 03 and this seems to be a common problem. Can
anyone please tell me how to put more tension on the belt.

Thank You
Dave
