Hey out there , seems i have an issue with my 91 sc, im loosing coolant somewhere, cant for the life of me figure it out. Dont seem to be coming from the water pump or hoses and the system wont pressurize. there is a small black fitting on the firewall that drips slowly and tastes like antifreeze. Any thoughts?
 
i cant think of any fittings for coolant on the firewall except heater hoses or if the heater core is leaking

That's probably the HVAC condensation drain and it's probably draining the coolant that's coming from your leaking heater core. ;)
 
That may make sense, the heater doesnt work as well as my 90sc did. Will the pressure tester work to find that leak as well? there doesnt seem to be any moisture on the inside of the car.
 
Thank you everyone! i will rent the tester this weekend and let you all know how it went. 1991 tbird sc bone stock 110k miles silver 5spd.
