Detailed Product Description

The Dayco 89347 accessory drive belt tensioner assembly is engineered to maintain optimal tension on the serpentine belt system in select Volkswagen models. Featuring a single pulley with a 70mm diameter and 24mm width, this tensioner operates in a counter clockwise direction to provide precise belt alignment and reduce slippage. The pulley surface is flat, which helps in maintaining consistent contact with the belt. The hydraulic assembly design allows for automatic adjustment of belt tension, compensating for belt wear and elongation over time. This ensures the accessory drive components such as the alternator, power steering pump, and air conditioning compressor function efficiently.
