This '88GT has only 40k miles, but spent most of its life stored in the sun - I'm reviving it. It's now running, passed smog, and the interior is finished. But among other remaining problems, the A/C lost its charge.
Temps are rising. My choices are:
1. Pay $$$$$ for an R12 recharge in the U.S. 2. Pay $ for an R12 recharge 25 miles away, in Mexico. 3. Convert to R134a. 4. Use one of the supposed R12 replacements, like Freeze12, HotShot.
You have a leak in the current system. You can recharge it with R12, but it will leak out. You will need to spend money and fix it right.... even if you still want to keep R12. (I am guessing your compressor is leaking).
