Dayco Serpentine Belt P/N:5040550
Dayco 5040539 serpentine belt for the 2013-2015 Ford Explorer 4-cylinder 2.0L, the 2016-2019 Explorer 4-cylinder 2.3L and other vehicles transfers engine power to the belt-driven accessories.
A worn belt can squeal at start-up or under load, or slip on the pulleys. Before you replace the belt, rule out a tensioner, idler or accessory pulley that is binding or noisy, because those parts can squeal too.
This belt is listed for a wide range of Ford and Lincoln models, led by the 2013-2019 Ford Escape 4-cylinder 2.0L, the 2013-2020 Ford Fusion 4-cylinder 2.0L and the 2014 Fusion 4-cylinder 2.5L, and each takes one belt. Open the "Vehicles it fits" section to check your exact model and engine.
