Description

It is used in Mercedes‑Benz Passenger engines to drive accessories such as alternators and power steering pumps. The belt's robust construction ensures long service life and reliable operation, while its precise dimensions of 30 x 310 x 520 mm fit the tight engine bays in German‑made vehicles. MPN A0009938702 confirms its authenticity and origin in Germany.

Key Features & Benefits

This belt is basically the engine's workhorse for powering accessories. It drives things like your alternator – that charges the battery while you drive – your power steering pump, your air conditioning compressor, and sometimes even the water pump. It’s a single, multi – ribbed belt instead of a bunch of separate V – belts, which makes it more efficient and quieter. Think of it as the connection between the engine's rotational power and all those important accessories. The engine spins, the belt transfers that spin to make everything else work. It wraps around pulleys on each accessory, transferring that force. It’s a pretty crucial link in keeping things running smoothly.

Symptoms, Risks & Replacements

If this belt fails, you’ll notice pretty quickly. You might lose your power steering, making it hard to turn the wheel, or your air conditioning will stop working. More seriously, if the alternator stops getting driven, your battery won’t charge and eventually you’ll be stranded with a dead battery. It acts like a shield, protecting more expensive components from potential damage if something were to go wrong in the accessory drive system. These belts do wear out over time, so replacing it proactively is a smart move. You can find a good quality Poly V – Belt at places like Fixparts Online, and they're usually pretty straightforward to replace, though it sometimes requires a few specialized tools.
