My wife has a 1995 Pontiac Sunfire 2.2 liter that began slowly leaking anti-freeze a couple of days ago. This morning I went out to inspect the problem, and find where the leak was originating, and I found that the leak was coming from a 90 degree hose junction coming out of the firewall between the two hoses used to supply the A/C unit. I found this kind of strange because I was expecting to need to replace a coolant hose, but I've inspected all of the hoses and none of them have any coolant on them. I checked the carpeting in the passenger compartment where you would expect to find moisture if the heater core were the problem, but it was dry on both the driver and passenger sides. Can someone tell me what this elbow hose junction is that is located between the two A/C hoses on the firewall, and what would cause the antifreeze to leak from this location.
Thanks.
