My '87 coupe's A/C is blowing cool but not cold so should I recharge the
original A/C and keep the setup all original for that future collector or
convert to the new refrigerant (R12 vs R34?)?
Surprise, surprise, the cost at local garages (for recharge or conversion)
and the nearby Chevy dealership (conversion only) is exactly the same --
Best to all.
This is an annual topic for this NG. Last year someone mentioned FR-12
as being the solution to everyone's problem. (Higher cooling capacity
than R134a, lower head pressure than R-12, ozone OK, no great conversion
cost, etc. etc.) These are some current web pages that take some of the
gloss from FR12. (keep in mind that there may be some "sour grapes"
here from outfits that don't want the expense of handling three
My A/C guy (Griffin's in San Diego) still has me on R-12 and doesn't
want to convert older Corvettes to R134a because of the high heat load
in the car. Last summer I asked him about FR-12 and he said he wanted
to wait. I'm cool for now and don't plan on another complete service
till next year. (Meanwhile the system is loaded with R-12 and a
florescent dye -- Costs a few bucks to shine the black light on it every
couple of months to spot minor leaks before they cause me to mortgage
Anyone else have any FR-12 experience ???
