Generator DECOUPLER: Notes

WARNING: This page is about a different car, the 2007 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.

The generator decoupler is used only with certain engines.

Two different type generator decoupler pulleys are used. One can be identified by the use of machined splines. See Fig 1. The other can be identified by a hex opening and will not use splines. See Fig 2.

Different special tools are required to service each different decoupler. Refer to following procedure.
