Can I replace R1234yf with R134 refrigerat. - Cars & Trucks

You can't it needs to be done by a dealer, they have to
Evac all the old R134 and replace unit and then fill with all new oil and R134. Expensive fix.

there are only two types of refrigerant (or normally called as freon): R12 and R134. R12 is designed for car model 2000 and below. though, some old car compressors can accomodate R134 provided that you change your auxillary fan (fan for your aircon condenser) since R134 is hotter than R12. Ask an aircon technician if your compressor can be charged with R134.

Most of the countries now ban the use of R12 since it is more harmful to our ozone.

Hi.

The freon is not poisonous. The gas currently in use is the R134 (no HFC's) replacing the old R12.

You can replace the condenser and then you have to charge the system with the right amount of gas and some lubricant.

chances are that its just low on R134 refrigerant ... .. thats the new stuff that replaced freon (R12) years ago ... R134 is a smaller molicule so it leaks out much more easily ... in many cars it has to be topped off periodically ...there are kits available (with a gage) that will allow you to top off the R134 yourself if you are mecanically inclined ... if not then professional places can test for leaks and other problems and recharge your system.

R12 but you can have it change to take R134

You need to replace it with a compatible oil for r134 and replace the offrice tube with a r134 tube.

first the a/c system need to be put into a vacuum before you add r134. how much r134 does you system need? too much or too little will both get you warm air. does the compressor come on? air in the system will get you warm air too.

good luck

1993 is a split year, if you have charging ports are a little bigger than the size of a tire valve stem then u have R12, if they are big then you have R134, most all Ford in 93 use R12. In the picture are adapters for a retrofit to R134, these screw on an R12 port, note the large cap R134 cap on the end of the adapter.

You might be losing A/C R134. You can buy a test kit and new R134 at a parts and the tster will tell you how much R134 you have in your system and you can recharge it at the same time if you need it --Good Luck
