How do I change AC from R12 to 134a?

How to Convert an R12 to the R134a System

  1. Discard any R12 refrigerant still in the system by taking your vehicle to a licensed air-conditioning professional.
  2. Open the engine compartment of your vehicle.
  3. Push the high side retrofit R134a fitting over the old fitting and use a wrench to tighten it.

Can you mix 134 with 134a?

Yes, the only difference is the labeling.

Can you mix different brands of 134a?

There is nothing different between brands of R134A unless there is something added to it. Never use leak seal, it’s included. The only difference is price.

What is the difference between 134 and 134a?

Some people use the terms R134 and R134a interchangeably, as seen in a casual search of automotive websites and storefronts, but they aren’t identical. The same number and type of atoms make up R134 and R134a, but the arrangement differs. Although R134 is technically a refrigerant, it’s less efficient at moving heat.

Can a Toyota condensor be converted to R134a?

The condensor will be fine, as long as you blow all the old oil out of it. The reciever/dryer will need to be replaced, the old ones NOT being R-134a compatible (though the new ones ARE backwards-compatible with R-12). The hoses should work.

Can You retrofit a car to use R-134a refrigerant?

There is NO reason to retrofit a vehicle to R-134a as long as the R-12 system is cooling properly and contains a normal charge of refrigerant. A/C systems designed to use R-12 will cool best when charged with R-12 refrigerant. Even if the system leaks, repairing the leaks and recharging it with R-12 is usually the best repair alternative.

Can a Toyota Tacoma be charged with R134A?

This makes sense because Toyota new that they were going to come out with the Tacoma soon and probably didn’t want to bother with more Hilux development. Now I just need to buy the parts, flush the system, change out the compressor & drier, evacuate the system and charge it with R134a.

Where can I get a conversion kit for a Toyota R12?

I bought a conversion kit made by Interdynamics at Walmart It includes fitting for 134A , 3 can of refrigerant and oil plus anti leak additives and a hose and guage for putting it in all for $35. My r12 system just had barley any pressure in it and no freon.
