OMIX-ADA 17453.73 Timing Belt idler for 02-06 Jeep Liberty KJ & Wrangler TJ with 2.4L

Your timing belt idler is a small pulley that helps route and stabilize the timing belt in its correct position. Signs that it's time to replace it include grinding noises from inside the timing cover, or slapping or scraping noises from the engine. Replace it with this OE one from Omix-ADA.
