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?

I do not know for sure but I think this may be a drain for the heater/air
conditioner case. If so, it would drain the water condensing off of the cold
AC evaporator coil and also any rain water that made it in there thru the
fresh air intake. If the radiator coolant leaks out of there, you have a
leak in the heater core. In some cases, a leak where the hoses connect to
the heater core can cause water to seep into the heater case and come out
the drain. Many cars do have a drain hose connected to lead the drain water
down under the car.

hope this helps a little.

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,
