Here's the story, I dont know why, but I absolutely dont like working under the front of the car. But I forced myself to jack it up and get out my flashlight and can find nothing.
About a year ago I drove the car and when I came home I had it in my garage messing around with the idle and such when I noticed a small puddle under the area where the drain plug is, the car was hot that day. I later pulled and put sealant on and tightened the drain plug thinking that was it. It lost about a pint at that time.
Recently I came home on a hot day was running the AC on a longer drive, and the car leaked about the same amount on my garage floor, I jacked the car up a day later investigated everything, I could see trace amounts in the fins of the radiator near that hose on the passenger side upper, but no leaks after running and driving it again. I cant determine where the leak is, it comes and goes it seems, but not often do I see it. It also appears the fans have been blowing coolant back onto the pass control arm as its wet slightly.
This may sound nuts but it seems to leak after I let the car sit and it starts to cool down, I never see leaks in parking lots, just my shop floor those couple times.
