That "cooler" in front of the radiator is your A/C condensor. If you punched a hole in it you won't see any fluid as refrigerant is a gas and will just escape into the atmosphere. Your A/C will not work either. Hopefully you just bent some of the cooling fins. They can be straightened out if you take your time. They make a special comb for them or you can use a pick if you're careful. Gotta take your time around the rad. area on any car or bad things happen.
