Motorcraft YS368 is an accessory drive belt idler pulley for Ford F-150 trucks equipped with the 5.0L V8 Flex engine. It helps the serpentine belt track correctly and maintain steady contact with engine-driven accessories, addressing belt slip, noise, and wear concerns when the original pulley is worn. Built as an OE-style replacement and tested to Ford engineering requirements, it supports a precise service fit for the listed F-150 applications.

Motorcraft YS368 Drive Belt Idler Pulley Features:

• Serpentine-style idler pulley supports the accessory drive belt path for components such as the alternator, power steering pump, air conditioning compressor, and water pump.
• Black-finished pulley is engineered to meet OE requirements for fit and function in supported Ford truck applications.
• Also referenced by manufacturer part number BL3Z8678D, helping technicians cross-check the replacement during parts lookup.
• Sold individually, making it suitable for replacing a single worn or noisy idler pulley in the accessory drive system.
