Detailed Description

Dayco A061382 is a replacement serpentine belt for the main drive system on 2016 Chevrolet Silverado 2500 HD and Silverado 3500 HD, plus 2015-2016 GMC Sierra 2500 HD and Sierra 3500 HD trucks with dual alternator applications noted in the fitment data. The EPDM rubber compound is paired with aramid reinforcement to support long service life, while the 6-rib layout and straight rib profile help maintain proper contact across accessory pulleys. This part number, A061382, is specified for heavy-duty truck accessory drive service where accurate belt length and rib count matter.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing belt
• Loss of proper drive to alternator and other belt-driven accessories
• Belt length mismatch after service on the main drive system
• Fitment issues on dual alternator heavy-duty truck setups

Installation Notes

Verify rib count, effective length, and outside circumference before installation.

For 2015-2016 GMC Sierra 2500 HD and Sierra 3500 HD, and 2016 Chevrolet Silverado 2500 HD and Silverado 3500 HD, confirm the main drive configuration and dual alternator notes in the application data.
