Motorcraft™ Serpentine Belt, V Belt
- Description:
This is the genuine Motorcraft air conditioning compressor drive belt for the 2015 through 2023 Ford Mustang, engineered to route engine power to the A/C compressor pulley on applications that use a dedicated secondary belt separate from the main accessory drive. Built from durable EPDM rubber with precision-molded ribs, it delivers quiet slip-free grip so the compressor spins at the correct speed for consistent cabin cooling. Drivers who need this belt often notice a chirp or squeal when the air conditioning engages, weak or intermittent cold air, visible cracking, glazing or rib chunking on the old belt, or belt dust collecting near the compressor. Replacing a worn belt restores full air conditioning output and prevents a sudden failure that can leave the compressor undriven. As a Ford OEM Motorcraft part it is cut to the exact length and rib profile the factory specifies, so it tensions correctly and tracks true across the pulleys. Inspect the automatic tensioner and idler pulleys for smooth rotation and replace them if worn, since a weak tensioner will shorten the life of any new belt.
