The Serpentine Belt plays a crucial role in the Jeep Wrangler by transferring engine power. The continuous Serpentine Belt connects the crankshaft pulley to the alternator, power steering pump, air conditioning compressor and water pump. This allows for simultaneous electricity generation, steering assistance, cooling of the cabin and controlling the temperature of the engine. In addition to saving space, the Serpentine Belt will reduce slip, thanks to the way the tensioner holds it tightly against each pulley surface and idler pulleys guide it. Compared with systems that use several separate belts found on other Jeep vehicles, this one belt does more and takes up much less space. When it is constantly rotating under heat and load, the Serpentine Belt may wear and a break would stop charging, cooling and steering, which can mean a Jeep can't run. By performing regular inspections for cracks, fraying or glazing, the performance of the Wrangler drive system can be confirmed. If the belt is intact, the Wrangler systems act in synchrony with engine speed. Having your Serpentine Belt checked out on time will help your Jeep continue to be a heavy-duty powerhouse while keeping every Wrangler ready for the daily commute.
