Good point. With the engine running, the fan can push a leak further rearward than where it originates from. And after a drive, coolant can collect in other places than the leak, too. Then when you park the dripping won't necessarily show you the exact location of the leak.
That said, you should at least try to use the drip locations as a hint when you first go a'lookin'. And no need to take the 'easy' way out by using some sort of dye or whatever.
I agree getting under it (w/the engine running if need be- like if you cannot locate an obvious location of the leak w/the engine off) is the surest way to tell. Using a hydraulic lift would be ideal. You'll need a good light, and whatever you do, DO NOT
get under it unless it's supported redundantly. Ramps alone are not enough. A floor jack alone or jack stands alone aren't enough either- you need two or more means of support, one backing up the other.
I could go on, but you surely get the idea- safety first
. People die every day from crush injuries.
