Hello I am repairing my 1990 builder ford bronco for the soul. He developed the infamous Ford "Twitter". This required cleaning the various pulleys AND purchasing a new belt and tensioner. Tried another big name auto parts - belt chirped after 500 miles. Thought it was an idler pulley. Cleaned the strap using the old shade tree mechanic method and the chirping was gone. For 25 miles! Bought this belt after reading the Ford Bronco forum. Best strap I've ever used on a vintage Bronco! The best! Calm. This belt has a different tread pattern that will work with old pulleys on A/C, P/S, alternatives, etc. We recommend. Regarding everyone.
