Oldsmobile/Buick Repair: coolant leak, rubber elbow, coolant leak

Question
Van
We have an 85 olds calais that has just developed a coolant leak. the coolant is coming out of a rubber elbow coming out of the firewall.
the air conditioner lines going inside are just above the elbow. any help would be appreciated.

thanks tom c

Answer
That rubber elbow is probably the condensation drain, but if coolant is draining, the heater core is probably leaking, and will need replaced.
Before tearing into it, though, make sure it isn't one of the heater hoses leaking by the firewall, and just following the copper tube in.
