no you can't. you must have the r12 removed and compressor oil then the valves need to have adapters installed so you can recharge the system no, but there are replacement freons (hot shot 414B) that can be added safely, after you empty the r12, and perform as the 12 did

∙ 12y agoNo, if you mix them they will gel and ruin the compressor and other components. Also, the oil that is used in the r12 system is not compatible with r134a and will not flow thru the system properly causing the clutch on compressor to not disengage. If you decide to retro fit your vehicle your need to replace compressor, orfice, condensor, the fittings and evaporator, so pretty much all the components and the system need to be evacuated and vacuumed so there willnot be any moisture or air in the system. And keep in mind r134a does not get as cold as r12

Can you put R12 in a R134 system?
If you mix r12 with r134 air conditioning system, it will cause a high pressure in your airconditioning system and eventually damage the compressor and the evaporator. R12 is only for r12 aircon and something with r134, it can't be mix.
Can you mix R134 freon with R12 freon?
They should never be mixed.
Can r134 freon mix r12 freon?
Only if you're trying to destroy your AC system. Never mix refrigerants.
Why cant you add r12 to r134 what happens?
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.

Does a 1991 Ford Taurus use the old freon or R-134a?
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

How do you know if r12 freon is in vehicle?
If if it a 1995 or older then it came with R12 installed. 1996 can be R12 or R134. 1997 up, it has R134/R134a. If you suspect it had R12 look for a label somewhere on the A/C unit signifying it has been converted. If you find it has R12 and is leaking and needs repairing, after the leak is repaired, convert it to R134a. R12 is far too expensive to use.
Where do you put the oil in your R12 compressor?
First of all, you don't use R12. Rather, R134 which has the oil included.
