I had the 2,8 V6 in mine and the Antifreeze should of discharged outside
of the vehicle . My 89 had a discharge hose on the outside.
The HC is in the midldle of the firewall behind the console. You can see
the black cover there under the dash. ABout 8 screws hld the cover in
place. There is a hidden screw buried in a deep pocket recession, close
to the firewall up over the gas or brake pedal. Very hard to get at
too........good luck. Its fairly simple once you get the cover off.
