• Description:

  This genuine Ford Motorcraft serpentine belt is the six-rib micro-V accessory drive belt for 2004 through 2008 Ford F-150 new-body trucks and the Lincoln Mark LT, with related application to Expedition and Navigator models, equipped with the 5.4L three-valve V8. It routes crankshaft power in a single loop through the tensioner, alternator, power steering pump, water pump, air conditioning compressor, and idler pulleys, driving every belt-powered accessory on the engine. Because a single belt runs the entire accessory system, wear or failure affects charging, steering assist, and cooling all at once, and a broken belt will strand the vehicle. Warning signs include squealing or chirping on startup, cracking across the ribbed underside, glazing, fraying, or chunks missing from the ribs, as well as a belt that slips under electrical or air conditioning load. Heat and age harden the rubber and open cracks, so inspection at service intervals and replacement before failure are strongly advised. Replace the automatic tensioner and inspect idler pulleys if they show bearing noise or reduced spring tension, since these directly affect belt life. Motorcraft construction delivers the correct length, rib profile, and durability for this 5.4L application.

• Applications: F150 NEW STYLE 2004-08, MARK LT.
