I still have a clutch fan on my truck. Its a 2004. I was wondering if only one large elctric fan with a new cooler thermostat would keep the truck at normal temp or slightly cooler. Or do i need 2 smaller fans. Problem is that my coolant resvoir for my supercharger is bolted to the fan shroud. Was thinking of keeping the fan shroud with an electric fan. Any comments and help is appreciated.
