Our 2003 Grand Caravan has a small oil leak getting on the ribbed pulleys. The car creaked even with a new belt. Put this belt on and the squeaks are gone! AWESOME design of this belt. The ribbing is reminiscent of a winter tire profile. The light reflected from the tape shows that fine grains are mixed into the tape. This baby grabs the pulleys and grips the snow tire like a tread cutting through the oil on the pulleys. Great design that really works. I will never buy another belt for our van ever again. This belt should be standard equipment on all vehicles.
