Didn't check coolant level of freezing in -30C weather, truck overheated in winter, probably freeing up the heater core and putting tiny hole in it. Truck smelled like anti-freeze whenever heat was turned on. A definite clue, with no cure but to replace the heater core! I think GM must have hanged the heater core from a wire on the assembly line, the built the truck from there out!!
