2000 Ford F150 6 cyl Four Wheel Drive Automatic
I think the heater core on my f-150 is going bad -coolant smell in cab and a " fog". The truck doesn't seem to overheat or leak coolant anywhere else. Is it still safe to run it without the heater for a few more days until I can get it to the repair garage? I don't want to ruin the truck or poison myself.
