Hi, I’m a new member. Drove 400 miles yesterday (highway) and had to add about 2 jugs of coolant. Stopped at Dealership (below freezing weather and no cabin heat) they think it was a “burp issue.” Seem like a large air space to have to add that much. The entire coolant capacity is only 11.6 quarts. Anyone else had this problem? Solutions? I’m thinking of deleting the truck. Thank you
