Why are you leaking antifreeze from under your car?

Answer 1

Because there's a hole somewhere under the hood that's letting it out, and it's usually in a heater hose. If you can't find it any other way, there's a blacklight detection dye you can put in the antifreeze. You put it in the radiator, then shine a blacklight (the ones they have at hardware stores are fine for this) on your engine. The leaking antifreeze will glow under blacklight.
