What type of freon does my car use?

What type of freon does my car use?

Originally, R-12 Freon was used in car air conditioners. However, it was found that when a car emits R-12 Freon, it depletes the ozone layer. The Environmental Protection Agency outlawed ozone depleting substances in 1994 and, as a result, R-134a Freon is now used instead.

What happens if you put R134a in a R12 system?

R134a systems work at higher discharge-side pressures than R12 systems, which could lead to compressor seals leaks. Additionally, since R134a is composed of much smaller molecules, it has a greater chance of leaking from an R12 system.

What refrigerant is compatible with R134a?

There are three refrigerants that can be used to replace R-134a: R-1234yf, R-152a and R-744. More on these replacements later.

How can you tell R12 from R134a?

If it is R12 the caps on the charge fittings will be about the size of the valve stem cap on your tires. If it was R134 then the fitting cap would be between the size of a dime or a nickel. r12 fittings are the same side for low and high side… r134 fittings are different sizes.

How do I convert R12 to R134a?

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.

How do you identify R12 refrigerant?

when new,it was r12. if it’s been changed over,look at the hi and low side ports. see if 134a adapters are screwed down on top of the r12 fitting ports. they will be larger.

What replaces R12 refrigerant?


What refrigerant is in my truck?

In most cars that are on the road today, R134a refrigerant makes the A/C system blow cold on hot days. Selected for its low flammability and safety, as well as because it’s kinder to the environment, almost every car built since 1994 is equipped with R134 refrigerant.

Which is the most expensive refrigerant *?

Does R1234yf cool as good as R134a?

R134a and R1234yf are similar, however, R1234yf was created as a more environmentally friendly replacement to R134a. The biggest difference between the two is that R1234yf is mildly flammable and does require special handling. Diagnosis of the air-conditioning system can be done in the same way as with R134a.

Can I convert 1234yf to 134a?

People assume that R-1234yf and R-134a can be interchangeable. Yes, the pressures between the two refrigerants are very close to each other, but they are NOT exact. Like with any air conditioning equipment the parts on your 1234yf vehicle are specifically manufactured to take 1234yf and no other refrigerants.

Can you mix 134a with 1234yf?

No, you cannot put R-134a into a HFO-1234yf system; here’s why…

Is 1234yf going away?

‘Repair U’: R-1234yf not going away, so auto body repairers, insurers need to be ready. Under an Environmental Protection Agency mandate, R-134a will be phased out and R-1234yf refrigerant must be in all new cars by 2021. The latter is already appearing in vehicles and is “here to stay,” he said.

What cars are using R1234yf?

Estimates put GM, BMW, Fiat, Land Rover and Jaguar at over 95% usage for 1234yf (BMW switched over its entire line to the new system in 2018) ; Ford, Honda and Volkswagon over 70%; Toyota, Subura, Hyundai and Kia over 25%; and Nissan, Mercedes, Mazda and Volvo with next to no conversions in their new models.

What year did they start using R1234yf?

What year did R1234yf come out?


How do I know if I have R134a?

To tell if it has been converted you can look for a sticker on the unit under the hood, which would indicate that it is R134a. And you can also look for R134a adapters, which would be located on the charge parts.

Is R134a going to be phased out?

USA: The US EPA is to ban a host of high GWP refrigerants including R404A, R134a, R407C and R410A in certain new products from as early as January 1, 2021. R134a is one of a number of common refrigerants that will be banned from use in new centrifugal and positive displacement chillers as of January 1, 2024.

What happens if you put R134a in a R1234yf system?

“r1234yf is not nearly as efficient as r134a” is apparently not true, at least from a quick read of a few industry papers just now. If you were to put R1234yf in a system designed for R134a, it looks like you’d end up with about a 10% loss of cooling capacity, but putting R134a into a R1234yf system would be a wash.

How much does a 1234yf recharge cost?

A pound of R-1234yf costs $80-$110, according to Abbot. That’s potentially a $200 materials bill, Collision Hub CEO Kristen Felder noted. Abbot said R-134a is $3 a pound, so if the shop doesn’t charge for it, it’s less of a big deal.

Does AutoZone check refrigerant?

When it’s time for an AC recharge, turn to AutoZone. We carry R134a refrigerant, PAG46 oil, AC stop leak, AC system cleaner, and more. AutoZone will test your car’s parts for free. We can test your car’s battery*, alternator*, starter* and voltage regulator while they’re still on your car.

Can a car lose Freon without a leak?

Refrigerant gas does not “wear out” like oil nor is it used up like fuel. In a properly sealed system the gas can continue being compressed and released over and over, so long as it doesn’t leak out.
