Hello all, I am new to the form as I thought being part of a group to answer or learn new things from people that actually have experienced issues could be very beneficial. I have a 2016, 6.7 - 3500. Truck has a full deletion and had the head gasket changed out with the bigger better studs applied. Pulled a 5th wheel all summer with no issues. Winter is near and after travelling 1800 km getting to our destination we parked. The next morning I noticed antifreeze under the front passenger side, lifted the hood and could see some antifreeze on the fender well bottom side of the passenger side. Temp out side was -10 c overnight. Started the truck up and went for a drive and everything runs great. Parked again and looked under neath about an hour later and I see no signs of antifreeze. Any thoughts as to what the issue could be? Possibly the cold? It seems weird to me?
