I just flushed the heater core (disconnected by PO years ago) let it soak with CLR and flushed with water hose.
I then noticed water dripping from the AC evap core drain on the firewall. So I'm assuming the heater core is pooched.
Whats the fastest way to remove the heater core? Can it be done from underneath the dash or does it have to come out?
Thanks for any guidance.
