I still have a small leak coming from what appears to be directly under the heater core, but not inside the truck, outside. It will leak out about 1 gallon of coolant every 4 miles. It won't leak cold and with the truck off, but as soon as I start driving it, it starts loosing coolant. I also have radiator vapors coming through my heater vents, whether the heater is off or on, or even set on A/C. Is it my heater core, like I think? Or could it be something else?
have the same problem?
