Uses no Freon which is R12. Uses R134 refrigerant.
A 1995 Cutlass Supreme should use R12 freon. The fittings are different between R12 and R134 so that they can not be accidentally swapped.
it uses R12 but it should be converted to R134
Freon is the trade name for R12. Your car contains R134 or R134a which is not Freon.
Unless It Has Been Refitted For R134 It Will Use R12. Best Way To Work This: Have A Good A/C Tech Update To R134 And Test Your System. You Will No Longer Be Able To Get R12 Well Some People Have Some Stashed About ( Cost Is High ) There Is Supposed To Be A Freon That Will Mix With R12 But I Have Heard That It Will Not Cool As Well. Good Luck
Initially used R12 . Almost impossible to get. Probably will have to change to R134
It doesnt matter the only available refrigerant is R134a and if you have an R12 system it must be retrofitted R134 is about $20 a pound and R12, if you can find it, is about $150 a pound
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.
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.
The 1996 Suburban uses r134 Freon. The fittings to add Freon are different sizes on r12 and r134, making it impossible to add the wrong type to your vehicle.
It came with r12. There are some aftermarket freon that will work with r12 called freeze12. If the system is empty I would change it over to r134. You would need a different offrice tube also. Did my 90 lesabre about 4 years ago.
Don't. R12 is so very expensive that you should have your vehicle converted over to use R134. You have a leak or you would be needing to add refrigerant. Have the leak repaired by a professional and have the system converted over to R134. The will remove all R12 & the oil from the system and replace it with R134 & the correct oil. They should pay you for the R12 due to how valuable it is. You may end up spending very little on this repair.
