Litens Automotive is the original equipment supplier for this decoupling alternator pulley to both Chrysler and Toyota. The Litens aftermarket replacement part uses the latest design technology used in the Toyota part, so while maintaining the exact Toyota form, may look different than the Chrysler part being replaced. Therefore the Chrysler part performance is improved versus the original equipment part. The Toyota part maintains the exact form, fit, and performance characteristics of the original equipment part (with the exception of not having the car manufacturer's logo or part number applied to the part). Decoupling pulleys are engine specific and can not be interchanged with other types of pulley technology. The Litens OAD type pulley is designed to free-wheel in one direction and, with an internal spring and damping device, softly engage in the opposite direction. The OAD is designed as a sacrificial part of the front-end accessory drive system, protecting other belt driven component as well as the alternator. The correct decoupler pulley ensures smooth, quiet performance as well as increasing vehicle gas mileage. Under normal driving conditions, the original Chrysler pulley will require replacement in approximately 50,000 - 60,000 miles. The original Toyota pulley will require replacement in approximately 100,000 -120,000 miles. This OAD decoupler pulley is supplied with a 17mm hex tool along with 2 sets of instructions covering correct removal and installation of the pulley on the existing alternator. The alternate replacement method (using the tool included) will require an air source (compressor), air gun, and a 17mm socket. The preferred installation method requires special tools detailed under the "product features" below.

The belt in my 2005 Chrysler Town & Country squeaks. I changed the serpentine belt and installed a Dayco No Slack Idler Pulley (part no. 89007) (from Advance Auto) but the belt still squeaks when idling. Do you think that the Litens Overrunning Alternator Decoupling (OAD) Pulley (part no.920834A) will stop the squeaking? The van has about 135,000 miles on it - not sure if the OAD pulley was changed before. Thx!

I have a special sound cominf from the alternator. Sounds like it is the bearings that gives horrible sounds when idling. Could it be the pulley that gives the noise when worning out?
