Welcome To Explorer Forum! Better to have smoke in the truck than smoke in your lungs?:dunno:

Welcome to this forum! You might have a coolant leak coming from the heater core. Does it smell like a sweet smell? How often do you refill the cooling system? Did you check the exhaust flanges to see if it's coming from the exhaust system? You wouldn't want to breathe carbon monoxide.:dead:
