R12
R12 is original equipment
1994 Mercury villagers come factory charged with R134a refrigerant. Vehicles built 1993 or prior were charged with R12 for note.
Was built for R12, should be converted to R134a
Unless it has been converted to R134, the OEM refrigerant installed in 1991 was R12 Freon. I suggest you have it converted to R134 if it has not already been done.
The type of refrigerant that an E 34 needs is R12 refrigerant. It is absolutely necessary that you do not put any other type of refrigerant into a R12.
It came from the factory with R12. Due to the high cost of R12, I would have it converted to R134.
My 1991 Plymouth Acclaim manual says mine is R12, but I can't say for the '92 It was built with R12, should be retrofitted 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.
R12, which is very expensive. Have it changed over to a newer refrigrant.
