Genuine BMW 850i Belt Tensioner Bolt

The BMW 850i Belt Tensioner Bolt keeps the serpentine belt perfectly tensioned to provide quiet auxiliary drive and instant power to all pulleys. Trusted for durability, this Belt Tensioner Bolt clamps the spring arm tight so that slip, squeal, excess heat, and voltage loss can be a thing of the past. On each and every BMW 850i from the first V12 coupes to later facelifts, the Belt Tensioner Bolt helps to steady the damper and eliminate vibration when the throttle is suddenly swung hard. The part works with two pulley systems, one for fixed alternators and one for overrunning clutches, so the newer Belt Tensioner Bolt has less stress on it and lasts longer than earlier hardware. BMW later added a corrosion-fighting coating that locks in factory torque and is resistant to road salt. By replacing a worn Belt Tensioner Bolt, drag is reduced, belt grip is restored, and fuel economy is boosted in minutes. Compatibility is across all 850i produced from 1989 through the final production run, thus providing owners the same Belt Tensioner Bolt no matter the trim. Consistent clamp force provided by the Belt Tensioner Bolt ensures that the water pump and power steering pump are provided with a continuous high speed to increase cooling efficiency, therefore increasing overall safety. Light but tough steel allows the BMW 850i community to trust this little fastener to drive for endless miles. When the Belt Tensioner Bolt is healthy, the grand tourer enjoys its famed smoothness on back roads and highways alike. Quick visual checks on any BMW 850i avoid expensive component breakdowns. That habit saves the spirited DNA located in every BMW 850i today.
