Antifreeze leaking out the bottom of my car?

Sounds like you may have a broken hose.

You'll need to let the engine dry and refill the radiator to find the source of the leak.

Take a close look at the hoses on the engine firewall, those are the heater hoses and one of them may have burst.

Does the car leak even if it's cold? ( like you park it for hours, then when you put some water or antifreeze it goes out ) ? if it goes even if it's cold, then it's not an issue with heating / and it's not a small crack in some place, it's a big one.

How much does it leak? does the radiator keep some water inside it or it get full empty? as if it goes full empty that means there is an issue with one of the hoses below, or with the radiator, it could be break or leak from bottom, or there is a break in the engine part that contain the water ( it can be fixed by wilding or maybe it needs to be replaced).

If the car gear is automatic, then you will probably find an oil cooler inside your radiator, check it's hoses if they also connected well and they have no cracks or holes, if so, then you need to replace the rubber hoses.

Engines have disks known as Freeze Plugs. The idea is if your engine ever freezes these plugs will pop out and keep it from cracking the engine block. If you have antifreeze leaking out the back of your engine there is a chance that you either have a cracked or loose freeze plug. You need to have a mechanic check it out as soon as possible because you could blow out the freeze plug and then you will need a tow.

Ya, its leaking because there is a hole.
