How would you repair a 1994 Olds Acheiva that is leaking coolant from a drain connection on the firewall?

The only hose connections at the firewall that contain coolant are the connections at the heater core. You either have a loose clamp or the compression fitting between the steel and metal parts of the hose itself are leaking. If there is coolant leaking out of an drain at the bottom area of the firewall, there's a good chance that it's leaking from the heater core itself, through a drain pipe which is the same drain pipe that removes water condensation from the air conditioning.

If it's leaking from INSIDE the firewall (away from the engine compartment) you probably have a leaking heater control valve or damaged heater core.

Your engine may have a leaking hose connection or a leaking gasket at the water outlet. It could also be a leaking hose.

The coolant sounds like it is leaking from the drain hole for the heater core. The drain is usually along the firewall and keeps the coolant from entering the vehicle should the heater core develop a leak.

You probably have a bad heater core. The heater core is installed in a plastic casing and the spout is there in case it starts leaking. This keeps it from leaking into the floor of the car.
