Pouring out antifreeze, car is not over heating

suspect internal engine problems since you continue to drive it while it is over heating...

check your hoses and make sure its not getting low because when it gets low the hoses can get hot enough to expand and spit out antifreeze without overheating

Condensation from your a/c can be found dripping off of a car. Make certain it is water and not coolant/antifreeze. If it has a sweet smell (coolant/antifreeze) then you may have a leak.

If the antifreeze is running out of the hole in the water pump housing, you need a new water pump.

I wouldsuspect heater hose or a hose of some type. Parts store has a telescopic mirror that could be helpful in lacating where to find the leak.cheaper than pouring anti freeze on the ground

Could be several things from radiator ,hoses,water pump, FREEZE PLUGS ,cracked head or block. You need to find out where the coolant is coming from to determine it.
If the car was hot and you poured fluid in it the block,head or head gasket could crack. If it was cold and you just had watr in it the block could crack or freeze plugs could have came out.

You may need to "burp" the system and get the air out. When car has completely cooled, take radiator a off, start car, let it warm up (but not overheat) and see if level drops. Add coolant/water mix to top it off. Never run straight antifreeze. At most a 50/50 mix of distilled water and antifreeze.
Air can get trapped in areas of the system when its been drained. Just monitor that temp and don't risk damaging the engine by overheating.

I would suspect the thermostat has stuck closed. Drain the system, heater on hot, flush the system, replace the thermostat, pour in pure water and see if that cures the problem. If it does then drain the system again and pour in a 50/50 mx of antifreeze and distilled water. You also need to make sure the cooling fan is working and the water pump is circulating coolant in the system.

overheating is most likely a bad thermostat, but the coolant loss is a second big concern. Does the exhaust look like steam? You could have a cracked block and the coolant is leaking into the engine. Also check the oil for contamination.

it could be antifreeze that was on the frame after changing the radiator the best way to tell is run car through a car that has the bottom wash or in a self wash and on... rinse... spray the area around radiator ...then check again later for antifreeze on ground
