So as the story goes, I drove roughly 90 miles yesterday and had no issues. Today I noticed a puddle of coolant under my car. (I know it was coolant, I did the taste test) I looked around the radiator, hoses, any cooling system component while the engine was cold, and found just a very little drip hanging off of my lower radiator hose at the water pump. (drip wasn't running, just residual) I hosed off the coolant on the parking lot and underside of my engine (I can't have the possibility of my neighbors animals getting in to that) and topped off my radiator and the puke tank. The puke tank was dry and my radiator was about 2 inches low from the filler. I took the car for a nice long drive, about 15 miles, running it up to operating temp, and higher than normal RPMs like 3k-4k. I can not get it to leak again, even after it has cooled off. I've never dealt or heard of an intermittent coolant leak. Anybody have any ideas as to what is going on???
