The current fan clutch available from Chrysler is a thermal unit



IIRC the MP fan package uses a viscous clutch. Either type will work but I figured having the fan clutch slip during hard acceleration would be easier on the belt and probably free up a little power. There's been an aftermarket viscous fan clutch on the GTX for 6 years without any cooling issues...
