Work kit like 2003 Jeep TJ w/4.0L. The idle bushing did not fit the existing idle bolt and washer. I had to buy a new washer for a new pulley. The belt didn't fit at all. I had to buy a new belt. But the belt tensioner works fine. I would not recommend this kit for a 2003 Jeep Wrangler with a 4 liter engine. to a good deal if more than half of the parts don't fit.
