Operator: I'm looking at myHaynes Manual which covers the 2001 Explorer. It does not mention the tube you describe. I also could not locate one in the location you described on my daughter's 1999. Allow me to make a suggestion. Allow the engine to get to operation temp the shut it off. Allow the water to drip onto your hand. If it is hot, it is obviously coming from coolant. If only tempid, maybe it is condensation. I will read from the manual regarding the heater core in your vehicle. "Regarding of the heater core, on the 2001 it is a difficult procedure the for home mechanic. The instrument panel must be removed, which involves many hard-to-reach fasteners and electrical connections." The evaporator housing must be removed. The instrument panel must be removed. The PCM and its heat sink must be loosened and set aside. Remove the bolts from the engine side securring the heater plemium from the firewall. Remove the screws securring the heater core cover on the plenium.

Regarding your post. Did you discover why the vehicle overheated the first time? Was it due to a lack of coolant? If there is a tube as you describe, and I do not doubt your post, then it must be a condensation drain tube, as the radiator system is a closed system. If it only leaks when the engine is turned off, how much is expelled and how long does it drip. Do you have to refill the radiator occassionally? You indicated it does not loose coolant?

yeah OJ, was thinking an evaporator drain too~
