I've got a 2016 ram 2500. Almost 200k on the motor. Last night i was hauling my 24ft trailer with utv for delivery and lost all power to the pedal. I could smell antifreeze but no visible leak. Finally found it was coming out the overfill of the coolant reservoir. Lines to radiator had no pressure. Released the air in the lines and pressure built back up and all lights went off. Ran great for another 2 hours until it lost coolant again. Truck never overheated once. Today I've only got 1st and 4th gear and no power to the turbo. Any thoughts?

Side note, turbo came back and no more leak. I don't get it
