What is the role of the drivebelts located at the front of the engine on Ford Expedition?

The drivebelts positioned at the front of the engine play an essential role in the vehicle's operation. They need to be regularly checked so that no damage is caused to the engine. All accessory components are driven by a single self-adjusting serpentine drivebelt in these vehicles. To inspect, open the hood and look for cracks, separation, fraying, and glazing. Inspect both sides of each belt and check the underside for even rib depth. The tension of the belt is automatic and does not require adjustment. Check wear indicator marks on the tensioner body and replace if outside the operating range. Relief tension to replace belt or remove old one then install new one properly fitting into pulley grooves.
