Alright so I just did a coolant flush and I was driving today and all of a sudden I smelled something burning up. I immediately pulled over and smelt under the hood, but the smell was not the same. I noticed that my coolant was dripping pretty heavily from underneath the car. I traced the leak to the bottom right corner of the car right by the drain plug. However around the drain plug was completely dry. When I popped the hood I noticed some seepage in the top of the radiator in the corner as well. So I was wondering if I am going to have to replace the whole radiator now or if maybe it is leaking because I overfilled it. It is only leaking when the car is hot and now that the car has cooled down it isn't leaking anymore. Any ideas?? Thanks
