NO! The problem is that the lubricating oils are not compatible, and the mixture will clog the system.
You do not want to buy Freon as it is very, very, expensive. Have the leak repaired, the system purged of all Freon R12 and the oil. Have it converted over to R134 refrigerant. You cannot just add R134 as the oil used in R12 is not compatible with R134. You will be money ahead by converting it.
They should never be mixed.
1993-95 for most.
Uses no Freon which is R12. Uses R134 refrigerant.
Why would you want to even consider doing this? R12 is no longer in production and as such it cost almost 4 times as much as R134. But to answer your question, use R12 in a R134 system and you will destroy the compressor as the oil is not compatible with R134 oil.
Freon is R12. Your 1997 Chevy uses R134 Refrigerant.
Check the ports to add freon--the low side is a large hose --the high pressure is the small line--on the large line if the valve is the large style----the freon is R134--if the valve is the small style it is R12--no longer used --retro valves are available to convert R12 systems to R134 R12 fittings can't be connected to R134 gauges, and vice versa. If it's R12 you won't be able to connect the hose from the supply can to fill it, or do anything else with R134 equipment.
Only if you're trying to destroy your AC system. Never mix refrigerants.
No, the two cannot be blended.
it uses R12 but it should be converted to R134
1994-1996 Depending on manufacturer.
Freon is the trade name for R12. Your car contains R134 or R134a which is not Freon.
