  Water Pump Belt, V Belt, jk5382a

• Description:

  This is the genuine Ford accessory drive belt for 21-25 F-150 with the 3.5L PowerBoost hybrid powertrain, routed through the water pump and engineered for the hybrid accessory layout. The belt is part of the front engine accessory drive that maintains coolant circulation and supports the hybrid system charging loop while the internal combustion engine is running. A worn belt typically presents as a wet-weather squeal, water pump chirp at startup, or visible cracking, glazing, and chunking along the rib face. The PowerBoost belt is unique to this hybrid powertrain and not interchangeable with conventional 3.5L EcoBoost belts. Inspect the water pump pulley, tensioner, and any idler pulleys whenever the belt is off; replace any pulley showing roughness, lateral play, or seal weep at the same service. Confirm correct routing against the underhood placard before final tensioning. Use only Ford-specified belt lengths and rib counts on hybrid applications; mismatched non-OEM belts often cause tensioner fatigue, accelerated pulley bearing wear, and intermittent hybrid system fault codes. After installation, run the engine and inspect the belt under load to confirm tracking and absence of edge fray.
