Re: 05 Grand Cherokee (3.7L) tensioner siezed
The tensioner is the same as the one on my 4.7L, which I just replaced last week. It is extremely easy to replace, not much mechanical know how needed. Pull back the tensioner, remove the belt, unbolt the tensioner, replace the tensioner and reverse the process. It literally took me about 20 min to replace both the tensioner and belt. I would replace the belt while you already have it off. No point in wasting the opportunity, ya know?
