A worn belt drive can show up as cracked or glazed belt ribs, a squeal or chirp from the front of the engine, or a noisy tensioner or idler pulley. Before you replace the kit, rule out a worn accessory bearing or an oil or coolant leak onto the belts, which can also make a drive squeal. Each engine takes one kit.
