i noticed since i started using my air conditioner this season that hours after i park my car (01 tl ) i have a nice litlle puddle of coolant...i took it to the acura dealer and they did a pressure test and reported no leaks....im not an expert on this , but is this possibly a heater core leak... i would think that would come under a pressure test but again , it maybe seperate....it seems like if i dont use the a/c , i dont have any puddles....any feedback would be greatly appreciated..again its not leaking while the car is running but later on after its been sitting there....
