Gravity put the drop on the oil pan. Antifreeze usually leaves a stain. Follow it up until you find the leak.

First I would check water pump or coolant tubes around the TB.

Pressure tester would find the leak quickly.

Put the front tires up on ramps, start it up and let it warm up for 15 minutes. You'll see it pretty soon after that. Keep looking after shut down too, sometimes they'll leak afterwards.

If you don't see a leak while its running, I'd let it get heat soaked, maybe go for a drive and let it get totally hot. Then come back, put in on the ramps, shut it down and look for leaks for a few minutes. After you shut it down the pressure in the cooling system will rise for a little while, some leaks will only leak at the higher pressures before it starts to cool down.

YEP, this is how I discovered my water pump was weeping. It would only do it after fully heated & then shutting the car off. Replaced the WP & problem fixed.
