Overview

Replace the long belt on your Coronado with this Conti Extreme Poly-V serpentine belt distributed by FleetPro Parts & Tires. It is a 12-rib belt, 86.3 in long, specified for the 2013-2015 Freightliner Coronado ISX Cummins accessory drive. A belt this long wraps a lot of pulleys, and every one of them is a chance for a glazed or cracked belt to squeal, flutter and start dropping the accessories it is supposed to turn. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Long Wrap, Full Grip: The Conti Extreme Poly-V Advantage

An 86.3 in serpentine belt is not a small part. It threads the full front of the engine, and it has to hold tension over a long span where any stretch shows up immediately as flutter between pulleys. The 12-rib profile answers that with seating surface: twelve grooves share the drive load, keeping contact pressure per rib low so the belt bites instead of polishing itself smooth on the first hard pull.

The Conti Extreme construction is aimed squarely at this kind of duty - the long, hot, high-mileage running that a Cummins-powered highway tractor does day in and day out. That is where a cheap belt shows its cost: not in the price of the belt, but in the second shutdown. This one weighs 0.81 lbs and ships in a 16 x 6 x 1 in carton, so it is inexpensive to keep a spare on hand.

At FleetPro Parts & Tires, we would rather sell you the correct belt for the drive than the closest one on the shelf. Match this belt to the 2013-2015 Freightliner Coronado with the Cummins ISX accessory drive, and check the tensioner condition at every belt change - a new belt on a tired tensioner will flutter and wear out on exactly the schedule of the belt you just removed.
