This is a DAYCO (6PK2050) grooved V-belt designed for the Mercedes-Benz W124 (200 E / 230 E) and W201 (190 E) models equipped with the M102 gasoline engines. It is the main belt that transmits power from the crankshaft pulley to the alternator, water pump, and steering pump. Thanks to Dayco's EPDM technology, it maintains flexibility against temperature changes, does not slip, and operates quietly.
- Advanced Technology: Dayco is an OEM (Original Equipment) manufacturer for heavy-duty and passenger vehicles. The belt surface is resistant to wear.
- 6PK Structure: The inner surface of the belt features 6 grooves (teeth), ensuring a perfect fit on the pulleys to prevent slipping.
- Long Lifespan: Made from a rubber compound that withstands high engine temperatures and continuous rotational tension.
- Quiet Operation: Its flexible structure allows it to rotate smoothly on tensioner bearings, preventing "squealing" noises.

Frequently Asked Questions (FAQ)
Does this belt fit my car with or without air conditioning? The presence of an air conditioning compressor in M102 engines changes the belt length. Additionally, there may be a difference in pulley sizes for some models. Please read the number on your old belt (e.g., 6PK2050) before placing an order.
What does 6PK mean? The "6" indicates the number of grooves (ribs) on the inner surface of the belt, while "PK" refers to the profile type. The groove count must match your vehicle's pulley structure.
Why does the belt squeal? When the belt wears out, it hardens and cannot grip the pulley surface, leading to slipping and a "squealing" noise. Additionally, if the tensioner block or damper is faulty, it can also produce noise.
