I've got an 07 expedition with a coolant leak, that I can't find. When I pop the hood open, I don't see anything wet anywhere. Behind the passenger wheel, there is a puddle. Some drips off of the metal, the rest drips off of the plastic molding in the wheel well. A few weeks ago, turned on the defrost and could smell coolant, but the reservoir still showed that it was full. It has been parked for the last couple days, and there was a good sized puddle under it today when I got home, checked the reservoir, and it is now low. Any ideas?
Could this be my heater core?
If so, how big of a job is it?
