I finally discovered what I think is the drain hole for and unexpected heater core rupture.
Had to slide under to the middle of the car to reattach the rubber loop hangers ( just behind the converter ) that stabilize the exhaust pipe to the unibody. Apparently when a new converter was installed the hangers were unhooked from the metal hanger hook. Now what year did they do that ?
Anyway...when I was looking at all that tangle of hoses & pipes around the rack & pinion unit I saw about a half inch long plastic projection ( drain tube ) sticking out from under the passengerside firewall area. Its view is completely blocked if your looking for it while laying under the engine or trans.
