ram1500 coolant

I recently found a spot in my driveway and so I looked under my truck and there was coolant on the underbody of the vehicle all the way back just before the rear wheels, I’ve checked around the water pump, pulleys, heater core, all the hoses and there’s nothing around the spot of the coolant...

I have RAM1500 2019 5.7h Canadian standard and I found that the coolant temperature reach 226F (108c) then the fan operate at high speed to cool the engine!! i was owned the classic 2018 with same 5.7h engine model with mechanical fan that keeps the coolant temperature at 205f most the time...
