I just had a new radiator installed by a local mechanic. After getting it back the car started over heating and smoke was poring into the car through the air vents. I opened the hood to see If I could find a leak anywhere and noticed a leak coming from a what looks like a connector on the firewall on the passengers side about half way down. The connector is about 3 to 4 inches long and curves down. Can anyone tell me what this connector goes to? I'm thinking it might be the heater hose. If it is, is it something I can just get cut to fit at a local auto parts store? Any help would be greatly appreciated.
