Accessory Drive: Description
WARNING: This page is about a different car, the 2004 Dodge Intrepid, 2004 Chrysler Intrepid, 2004 Chrysler Concorde, and 2004 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
The accessory drive system on 2.7L and 3.5L engines utilizes two different belts. A conventional V-belt drives the air conditioning compressor on 3.5L engines, a Poly-V belt on the 2.7L engine. A Poly-V belt drives the generator and power steering pump on all engines.
