Motorcraft™ Serpentine Belt, V Belt
- Description:
This genuine Ford Motorcraft accessory drive belt is the six-rib serpentine belt used on 2011 through 2019 Ford Explorer models equipped with the 3.5L non-turbocharged V6 and the heavy-duty alternator option. The heavy-duty charging configuration uses a slightly different belt routing and length than the standard alternator, so this specific belt is matched to that layout to maintain correct wrap and tension across the crankshaft, water pump, power steering pump, alternator, and air conditioning compressor pulleys. Molded from durable EPDM rubber with precision-ground ribs, it delivers quiet, slip-free power transfer and resists the heat, cracking, and glazing that shorten the life of an aging belt. Symptoms of a belt that needs replacing include a persistent squeal or chirp on startup, visible cracks or missing chunks along the ribbed surface, fraying edges, or intermittent charging and accessory faults. Because one belt drives every engine accessory, letting it fail can leave the vehicle without power steering assist, battery charging, or coolant circulation. This Motorcraft belt is built to the original factory specification for the heavy-duty alternator application, ensuring proper fit and tensioner travel. Inspect the automatic tensioner and idler pulleys during installation for the best service life.
