I have a 1997 Plymouth Voyager that has had problems with the belt tensioner. The belts keep slipping off! I have had the belts and tensioner replaced at least 4 times in the last 5 years. It has happened again!!! This time there is a replacement kit , not produced by Chrysler, that I hope will solve the problem. Wish me luck.

 

4 times in 5 years i would say its NOT the tensioner it maybe a temp fix because a new tensioner may hold the belt tight enought so that it does not fall off. I take it u have a 3.3 or 3.8 correct?

 

Have got the same problem on my 93 voyager 3.0L.Only on mine when I reinstalled the belt (again)I snapped off the bolt on the tensionerin the oil pump housing.GRRRRRRR!Im in the process of removing the pump to either try and remove the bolt or change the pump but I am having a hell of a time removing it.Cant figure out why it dont just slide offthe crankshaftits only got five bolts holding it.Any hints or ideas? Thanx in advance.Bob.
