So at the risk of sounding like a complete idiot, I have a coolant leak on my wife's Pilot. I'm fairly confident that I've located the somewhat obvious source, but since I don't diagnose coolant leaks every day, I thought that I'd confirm before I go off replacing the radiator. The attached photos were taken looking down into the driver side of the engine bay, toward the front of the car (bottom of the radiator). What I think that I'm looking at is a small pool accumulating in some sort of catch tray, and some surrounding dried splatter from where it's been overflowing the tray. The only thing that looks a bit odd to me is the color...I'm accustomed to coolant having a more yellow-green appearance, and this is almost blue-green. Again, I just wanted to get some more experienced opinions before I replace the radiator. Thanks in advance!
