Description

Keep the fan and every belt-driven accessory turning with the Gates Serpentine Belt K100789HD. This is the heavy-duty FAN-drive belt, and it installs as a direct-fit replacement for the 2018-2019 MACK CHU, the 2018-2019 MACK CXU, and the 2018-2022 MACK PINNACLE. It routes and loops over the drive pulleys to transfer crankshaft rotation to the fan and other accessories.

Drive belt: transmits power from the crankshaft pulley to the fan and other belt-driven accessories along the factory routing.
FAN position: cataloged for the fan-drive belt location on the listed applications.
Direct-fit: replaces the original belt on the listed MACK trucks.

A worn belt can show cracked or glazed ribs, chunking, squealing, or fraying edges — signs this belt may be due for replacement. If a failing belt is the cause of those symptoms on your truck, this Gates belt replaces it.
