What is your question?
Over heats even after a new radiator and thermostat during the cold months of the year not the warmer months?
How long has your 2005 Dodge Ram 2500 had this problem?
1 year
ASSUMING there is sufficient *ANTIFREEZE* concentration in cooling system to prevent coolant icing.. Weak (insufficient) antifreeze to water mixture will cause overheating as the coolant turns to slush. That’s the ONLY thing I can think of. Good luck!
