coolant leak
I have an 07 explorer XLT 4.0 V6. It is leaking coolant from somewhere and I can't find out where. There is no smoke or smell from the exhaust and there is no leak on the ground either or on top of the motor. I don't smell in the cabin either so I know it's not the heater core. It only leaks when the car is in motion, if it is standing still even with engine running it does not leak. It goes through almost 2 jugs of coolant every three weeks. Any ideas on where to look.
