Bokra سير اكسبيديشن بلاستك 2007-2014

The plastic drive pulley (guide or tensioner pulley for the engine belt) for Ford Expedition models from 2007 to 2014 is the round piece made of reinforced plastic that is installed on the belt tensioner system to guide the belt path (multi-ribbed belt) and maintain proper tension around all pulleys. The importance of this plastic pulley lies in its being the primary responsible part for ensuring smooth belt rotation without slipping or vibration, which keeps the attached devices such as the alternator, power steering pump, and air conditioning compressor functioning efficiently, while reducing weight and noise compared to metal pulleys. The high-quality heat and corrosion-resistant plastic and the sealed internal bearing guarantee quiet, smooth rotation free from roughness or squealing sounds, and a long lifespan. Replacing the damaged or noisy pulley that emits squealing or vibration restores proper belt tension, and any annoying noise coming from the tensioner area disappears immediately, allowing your vehicle's devices to operate smoothly and quietly. **Specifications** - Compatible models: Ford Expedition 2007 – 2014 - Part name: Plastic belt pulley (engine belt guide pulley) - Material: Plastic - Storage number (SKU): 6L3Z-6C348A
