no --it cannot. R12 gas operates at a far lower pressure that r134a so if you want to use r134a gas you will have to replace compressor ,evaporator and condenser and have a cooling fan for the condenser fitted
Unless the labels are missing from the car, it will state which type of refrigerant is used. Could be either R12 or R134a. If originally R12, it could have been replaced by R134a with an upgrade kit. The easiest way to tell if the labels are missing, is to look at the valves on the AC system. If they are Schrader valves (same as used on tires), then it is the older R12. If the caps are Red (high pressure side) and blue (low pressure side), then it is R134a. The sale of R12 to non-certified mechanics is illegal in all states as far as I am aware. R134a is available in most states and retro-fit kits are available in most states.
I have done the retro-fit on 2 vehicles with acceptable results. It is recommended to remove all the old R12 with a vacuum pump. Autozone (in my area anyway) rents these.
Good luck if you need and decide to retro-fit yourself.
well in that year they used r12 refrigerant ! today they use r134a refrigerant they are not interchangable if you have already converted to r134a they you can call toyota and ask for specific amount although you really dont need to know all you need is a can of r134a with a gauge on it if it 75-80 degrees outside the pressure should be between 40-45 pounds if its 85-90 degrees between 45-50 pounds on the low side were you add it so basiclly keep adding till those pressures are reached
please do not add r134a if you have not had system converted over from r12
Good day,
The problems that occur on R12 systems are no different than the newer R134A units.If it involves using R12 it would be a little more expensive, but since they use approx. 6 to 8 ounces it really isn't that bad.
The R12 spec on the Saturn Threw 93, capacity R-12 2.1 to 2.25 lbs.
On the 94 -98 S-series cars; per
the Haynes A/C manual these systems should take 6.5 oz of Ester oil and
24 oz of r134a refrigerant.
The amount of refrigerant
required is printed on a label in the engine area. I think its 1.5lbs or
24ozs or two 12oz (net wgt) cans if your system is the R134a.
Thank you for using fixya and just make sure that your have the right system in your Saturn, it's going to be R12 from 1993 and earlier and 1994 will be R134a. Note: at if your not the original owner, your system may have been converted to the R134a.
If it has screw on fittings then r12. If the fittings are quick disconnect type then it takes r134a. I would do a r134a system conversion if needed because of the availability and price of the r134a refrigerant.
You can use R134a compressors with the Poly oil in them and use R12 or R134a (flush the remaining old mineral oil out of the system first). Match your BTU requirements.
