We were working on restoring the A/C system in a first-gen Firebird convertible and discovered that an owner from eons ago (or someone he or she hired) cut a hole in the inner fender to pull out the heater core and replace it.
How about your Pontiac? Do you know if its heater core was replaced? Have you ever checked to see if someone took the shortcut and cut a hole in your passenger side inner fender to remove it.
We'll show you the proper way to remove a heater core and how you can send your heater core's fiberglass enclosure out for restoration to specialists like Classic Auto Air (www.classicautoair.com).
Its in a future issue of High Performance Pontiac, so be sure to look for it!
