Detailed Description

Roadmax 6K942AP is a 6-rib serpentine belt designed for accessory drive belt system service where the correct length, rib profile, and material construction matter. The EPDM belt construction helps support long-term wear resistance, while the polyester cord structure adds strength for stable operation under engine-driven accessory loads. If you are replacing a worn serpentine belt on a Mercedes-Benz C240, C320, or ML55 AMG, or servicing a Ford E-Series van with the correct belt specification, this part provides a straightforward standard replacement choice.

This part cross-references Gates K060942 and Bando 6PK2390 for the same application.

What This Belt Helps Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing serpentine belt
• Loss of belt tension caused by age-related stretch
• Accessory drive noise during engine operation
• Service replacement for vehicles using a 6-rib, 94.19-inch effective length belt

Installation Notes and Tips

Verify belt routing against the vehicle’s underhood diagram before installation. Confirm the required belt length and rib count match the original application, especially on Mercedes-Benz models with chassis-number or date-specific notes such as C240, C320, E500, S430, and ML55 AMG. Inspect pulleys, tensioners, and idlers for wear before installing the new belt, since damaged components can shorten belt life and affect tracking.
