What is a Mercedes-Benz B-Class accessory belt?

The accessory belt (also called the auxiliary belt or serpentine belt) allows the engine to drive peripheral components such as the alternator, air conditioning compressor, power steering pump, and sometimes the water pump.

When should you change the Mercedes-Benz B-Class accessory belt?

Typical replacement is every 60,000–120,000 km or 4–6 years. Signs of wear include: squealing noise (especially at start-up or in wet weather), visible cracks or fraying. Always replace the tensioner and any idler pulleys at the same time.

Is it difficult to change the Mercedes-Benz B-Class accessory belt?

Difficulty level 2/5: technically easy. Key steps: note the belt routing before removal, release the automatic tensioner, slide off the old belt, replace tensioner and idler pulleys, route the new belt, release the tensioner to apply tension.
