Any 1998 model year vehicle will use R134a.
No , it's R134-a
This is the transition year. It can be R12 or R134. It is listed on the unit. The fact that R12 is no longer being produced makes it extremely expensive. Convert it to R134.
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.
A 1999 Ford Mustang has r134a in the air conditioning system
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.
If your vehicle is a 1994 or older is contains R12. 1995-96 It man contain R12 or R134. After 1996 it will contain R134. It is listed on a label near the compressor dryer. Engine size means nothing.
R134a.
Should be R134
94 went to r134. but if it is really a 93 chassis, I wouldn't know I think that was the change over year from r12 to r134
R12 was used up until 1992. R134 Is what is used now, and you can even check to see if yours was converted from R12 To R134A
A 1986 Ford Bronco II would use R12 unless it has been converted
R12 134A pre 1996 is r12, after is r134
