Tensioner – V Belt Od76Xid17Xh28 (M271) (Mercedes-Benz C-Class W203 / W204 / E-Class W211 / SLK-Class R171 / Sprinter) is a critical component designed to maintain proper tension on the V belt system of selected Mercedes-Benz models. This tensioner helps ensure consistent belt alignment and tension, preventing slippage, noise, and premature wear that can affect engine accessories driven by the belt.
The tensioner is compatible with Mercedes-Benz vehicles including the C-Class W203 and W204, E-Class W211, SLK-Class R171, and Sprinter series. It is essential to compare the dimensions, specifically the outer diameter (OD76), inner diameter (ID17), and height (H28) parameters of this tensioner to the existing unit on your vehicle to confirm fitment. This helps maintain optimal belt function and accessory drive performance.
When replacing a tensioner, matching the correct part ensures proper belt tension and smooth operation of components such as the alternator, power steering pump, and air conditioning compressor. If unsure about compatibility or identification, consulting the relevant vehicle documentation or seeking advice from a parts specialist is recommended.
