Belt Tensioner

I thought that the belt on my '02 TJ 6 cyl. Sport was the problem so I tightened it up a little but that did not seem to fix the problem. Do you think that it is the belt tensioner? Is it hard to replace? How much should I expect to spend on the part? Thanks, Scooby

Since your model year TJ has a spring loaded automatic belt tensioner, it shouldn't need adjusting to make it tighter. As asked by 4Jeepn, what's the issue where you felt the belt needs to be tighter? By pushing HARD on the belt between its widest unsupported span with your thumb, it should deflect about a half-inch. :)
You are probably right, I did not tighten it, I guess that is what I thought I was doing! What causes the squeal? It seems to come and go at idle, but I cannot hear it under power. Thanks again, Scooby
Bad bearing in a idler pully :eek:

Is this a dealer only part, or is this something that I can buy at Auto Zone? Is it hard to replace? Thanks again, Scooby
