The Jeep Commander Serpentine Belt transmits engine power to important components that control the vehicle's cooling, steering, and other systems. The Serpentine Belt within the Jeep Commander's engine bay is a single belt; it wraps over the alternator, power steering pump, air conditioning compressor and the water pump in a continuous loop. Idler pulleys and a self-operating tensioning device serves to direct and tighten the belt which allows for smooth energy movement without slippage. This layout is spatially efficient when compared to earlier versions that had multi belt systems within it. Every Jeep Commander uses this Serpentine Belt to make the air conditioning system run, circulate the coolant, power the steering system and charge the battery. Due to the continuous rotation of the belt under heat and load, it gets worn out with use, and if it breaks down, the vehicle can soon lose cooling, steering assist and electrical output. The Serpentine Belt can be visual checked easily for cracks or glazing before it fails and leaves the vehicle stranded. A properly tensioned and intact Serpentine Belt is important for keeping a Jeep Commander running.
