"As for the fan - it is really easy to install a 30 amp "Fog lamp relay" from your local auto parts store, and energize it with a switch in the cab of the truck when you see a steep hill coming up (on a hot day). Then run a #10 wire from the battery to a 20 - 30 amp fuse, to this new relay, to the fan input 12 volt power. When you turn on the switch, it will bring on the high speed fan.
do we disconnect the other power wire from the fan ??"
Probably a fair bit of machinist work --- that is NOT an electric fan.
Actually that is the norm for the engine, when the fan cuts in the temp should not go any higher.
