Product Description

Keep your Mercedes-Benz engine running smoothly with the Arrowhead Tensioner Unit V Belt, designed specifically for the ENGINE VEE BELT TENSIONER system. This unit maintains the correct tension on the engine's V belt, ensuring optimal performance of essential components like the alternator, power steering pump, and air conditioning compressor. Proper belt tension is vital to prevent slippage and premature wear, helping your vehicle operate efficiently.

This Arrowhead tensioner is compatible with select Mercedes-Benz models. It is important to match the part to your specific vehicle by confirming the model, year, engine size, and engine code, as fitment can vary within the Mercedes-Benz range. If you are unsure, our team at MiMi Auto Parts is ready to assist you with fitment queries.

A worn or failing V belt tensioner can cause a range of symptoms, including squealing noises from the engine bay, visible belt wear, or fluctuating accessory performance. If you notice the belt is loose, misaligned, or there are unusual vibrations, the tensioner may be the culprit. Ignoring these signs can lead to further damage to the belt and connected components.

Replacement of the V belt tensioner is recommended if you observe any of these symptoms or during routine belt replacement intervals. Timely replacement helps avoid unexpected breakdowns and ensures all belt-driven accessories function as intended.

Trust MiMi Auto Parts for reliable Arrowhead components and expert advice. We offer nationwide delivery in South Africa, making it easy to get the right parts delivered to your door. Always confirm your vehicle details before ordering to ensure correct fitment.
