I agree with Ray -- heater hoses (most likely) or o-ring (less likely, but possible). Run the engine up to temp with the heater on and feel the underside of the connections at the firewall.

A second, perhaps foolish question is: are you sure it is coolant? From the location it might possibly be the clutch slave cylinder starting to leak... uhm, that's assuming we're talking the 3.0L V6, right? <img src="/forums/images/graemlins/cyclops.gif" alt="" />
