Is it possible to use 134a instead of r12
These oils can cause explosions because they are not compatible. R134a also has a smaller molecule that r12, so if there was a small leak with the r12 you may have a bigger leak. R134a is smaller than r12 so it can leak through older hoses that were used for r12.
So, how can you convert r12 into r134a?
Converting an R12 to the R134a system
- Take your vehicle to an authorized air-conditioning professional who can dispose of any R12 refrigerant that is still present in the system.
- You can open the engine compartment.
- To tighten the retrofit R134a high side fitting, use a wrench.
Is there an alternative to r12? R-134a is the best alternative to R12. R134a's chemical name is tetrafluoroethane. Its chemical formula is CF 3CH 2F. It is a hydrofluorocarbon, HFC. It has very low greenhouse effects and no ozone depletion.
You might also wonder how much it costs to convert r12 to R134a.
Re: R12 to R134 AC conversion It is more efficient, doesn't require flushing, and will likely stay there for longer.
What is the cost of 134a in an r12 system
Calculate how much R134a you need. R134a weighs less than R12 so you will need to convert the charge weight during retrofit. To get the best cooling, fill the system with 75-85% of the factory recommended capacity.

How do I drain my AC coolant from my car?
How to Remove Refrigerant from Car AC?
- Switch the indoor thermostat off.
- Locate the low-pressure side of your refrigerant and the suction side of the compressor.
- Use your wrench to close the service valve that you will see on the condensing unit's low-pressure side.
- Now, close the high-pressure side's service valve just slightly.
How can I tell what refrigerant my car has?
There's a sticker under the hood, somewhere right up front, that tells you which refrigerant was used in the factory fill, and it also tells you how much. That sticker is part of SAE Standard J639, which provides safety and design standards for automotive air conditioning refrigerant systems.

Can you mix r12a and r134a?
It's illegal to vent R134a into the atmostphere! Just adding R12a to a 134a system doesn't work very well because a 50/50 mix is very inefficient. If you don't have a vacuum pump, you can still make it work though. First warm up the car with the air on and then turn it off.
