Actually I did turn on the AC while driving yesterday but only for about 3-4 minutes mainly out of curiosity to see that it could still blow cold air. (I seldom if ever use the AC) but once I could tell it was working I turned off the AC and continued to drive for about another 30 min. and maybe another 15 miles.
I think it’s strange that nothing leaked for more than 6 hours after parking the car. It wasn’t until this morning, a full 10-12 hours later, that a small amount of coolant was under the car. Also, I don’t get it why coolant would relate to running the AC anyway, since the AC uses refrigerants not anti-freeze. On the other hand the heater, I believe, does pass air through the heater core to blow hot air..... but not cold.

Mystery still prevails I guess.......a question I have is why it doesn’t leak until the car is totally cooled down. I would think I’d be leaving spots of coolant all the time.
