Gates Timing Belt Drive Component Kit 38342K fixes a recent issue with the 96 Dodge Caravan. The OEM idler pulley has a smooth surface that will cause the multi-ribbed belt to squeak or slip, especially in wet weather. The Gates Component Kit replaces the Original Equipment idler pulley with a grooved pulley for a non-slip, better grip, eliminating belt slippage and squeaks. This inexpensive solution gave us more security when traveling and was definitely worth the investment.
