Chevrolet: !998 Chevy Baretta question, help please

I am having a problem with a hole in the firewall. It has nothing to
do with the heater core as I can account for both the inlet and outlet
hoses from that. It is a hole about the size of nickel and water
drains out of it. The car came that way and I am wondering what this
could be and where it goes. When I fill the radiator up, the water
drains out of this hole. I need to know where the hose for this hole
is supposed to go? Something was there, maybe not even a hose or tube,
but I sure could use your help. Any ideas, please?

Thanks Don, apparently what you suggested is the problem. In addition
to your response, I called a few dealerships and they all said they
same thing you did. Thank you SO MUCH!

It's people, such as yourself, that proves that they are good decent
people in Internet land willing to help others and that is a good
thing.

Best always, buddy,
