Gates DriveAlign Automatic Belt Tensioner Assembly

What you get in this box is a Gates DriveAlign automatic belt tensioner assembly, part number 38217. This assembly is designed to keep your engine's accessory belt properly tightened. A correctly tensioned belt is crucial for ensuring all your engine's accessories, like the alternator, power steering pump, and air conditioning compressor, run smoothly and efficiently. Without the right tension, the belt can slip, leading to reduced performance or even failure of these vital systems.

Gates is a well-known name in belts and tensioners, and this DriveAlign unit is built to meet the demands of your BMW's V12 engine. It's an automatic tensioner, meaning it adjusts itself as the belt wears or as temperatures change, so you don't have to worry about manual adjustments. This helps maintain consistent tension over time, which is important for belt longevity and preventing premature wear on both the belt and the tensioner pulley itself. Installing this assembly ensures your accessory drive system operates as intended, keeping your 750iL running reliably.
