Hey guys new on here. My 2012 3500 6.7 with 34 k miles was wrecked and got new serp belt, fan, clutch, radiator, condenser and all that. A week after leaving body shop, pulled up to stop light and heard a racket. Under the hood I was dumping all my antifreeze. Pulled into parking lot and somehow the wiring on fan clutch got ripped around and ripped out of both plugs and shot into radiator. The clutch came from advance and everything else was OEM. I know the coolant system was bleed properly and the shop run it for hours ensuring everything was as need be. I'm not the owner of the truck but the tech who put it back together after wreck. Does anyone have any idea what might be going on with this thing? I have my theories but would like some insight please.

The wiring that i pulled out of lower fan shroud.
