I have a 1986 M1008. It has a permanent battery tinder, oil pan heater & factory coolant heater. Thought we had unplugged the oil pan & coolant heaters & plugged in the battery tinder yesterday but when I went out to the truck today I realized the coolant heater was still plugged in. Checked the overflow and it was completely empty but pulled the radiator cap and it was almost completely full. There are no sign of any leaks externally, exhaust, etc..... It was in the 30's last night and in the 70's today. Is it possible that the heater cooked the coolant off? Thank you
