It came with R12 Freon. As R12 is cost prohibitive, have the unit converted to R134a refrigerant or a similar substitute.
First off it contains no Freon. The refrigrant used is not Freon R12 but is R134a. Freon is extremely expensive but R134a is around $7 per 12 ounce can.
2 pounds of r134a. Not r12.
None, the refrigerant is R134a not Freon which is R12.
It came with R12. Due to the high cost of R12, I suggest you convert it to R134a.
There is only one Freon, and that is R12. R12 Freon came installed in your 1991 Chevy. It may or may not have been changed over to R134 Refrigerant. If not change it over, as the cost of R12 is unbelievably high an is no longer in production.
Freon (R12) has not been installed in any vehicle since 1995.
R12 unless it has been retrofitted. I would suggest have it changed, as the cost of R12 is prohibitive.
easily. Buy a converter from local parts store for r12 to r134 system should cost 6-10 dollars. Screw converter onto AC fittings and charge as a normal system Freon is about the same cost.
It is still possible to aquire R12 Freon, but the cost is excessive. My advice is to convert the system to R134a.
You cAnt sorry
