What Kind Of Refrigerant For My Car

Newer vehicles rely on R-134a refrigerant, also known as HFC-134a. A lot of older A/C systems that depended on R-12 as a refrigerant can be retrofitted to use R-134a.

How do I know what refrigerant my car uses?

If you are still concerned you might be using the wrong refrigerant, look under the hood. There is a sticker under the hood that will show you exactly what refrigerant you should use for your engine.

How do I know if my car is r12 or 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.

Can you put R134a into a R1234YF system?

yes R1234yf Freon gas can be replaced by R134a; the newer systems were designed with this in mind so no, there will be no damage to the compressor but some time in the future doing so may become illegal. >>.

What air con refrigerant does my car use?

The vast majority of cars on the road in the UK use one of two types of refrigerant – R134A and R1234YF. If your air conditioning system requires R134A gas the cost to recharge is £49.95.

Does my car use R134a refrigerant gas?

R134a refrigerant gas was the most commonly used refrigerant gas by vehicle manufacturers in recent times up to 2017. The MAC Directive only applies to new vehicles since the start of 2017, so all vehicles currently using R134a are still able to continue to use that refrigerant.

Is Freon the same as refrigerant?

Freon is a non-combustible gas that is used as a refrigerant in air conditioning applications. This freon undergoes an evaporation process over and over again to help produce cool air that can be circulated throughout your AC system.

Can you mix R134a with R12?

As previously stated, R12 systems usually use mineral oil, which is incompatible with R134a.

How do I switch from R12 to R134a?

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

Can I use 12a instead of R134a?

HC-12a, also called ES-12a, OZ-12a, DURACOOL 12a and Hydrocarbon Blend B, is a “drop-in” replacement refrigerant for Freon-12 and to a lesser extent, R-134a. Unlike R-134a, HC-12a is completely compatible with the hoses and oils used in R-12 systems, making the conversion much easier to accomplish.

How can you tell the difference between R134a and R1234yf?

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.

What happens if you put the wrong refrigerant in your car?

You cannot mix refrigerant types, and putting the wrong refrigerant in your car will cause damage to the air conditioning system! If you’re not sure which kind of refrigerant your vehicle takes, DIY A/C charging may not be for you.

What cars use 1234yf refrigerant?

Ten of the OEM groups currently produce more than 90% of their vehicles sold in the US using R-1234yf. These OEMs include: BMW, FCA, Ford, GMC, Honda, Hyundai, JLR, Subaru, Tesla, and Volkswagen Group.

Are all 134a refrigerant the same?

Are all R134a refrigerants the same? Yes, almost all the r134a refrigerants are the same. However, the properties of leak detection sometimes change in the refrigerant. So, you can use the leak detector.

What is the most commonly used refrigerant?

The most common refrigerants used for air conditioning over the years include: Chlorofluorocarbons (CFCs), including R12. This is known to contribute to the greenhouse gas effect. Hydrochlorofluorocarbons (HCFCs), including R22. Hydrofluorocarbons (HFCs), including R410A and R134.

Can you buy Freon for your car?

If you’ve confirmed that your vehicle uses R-134 or R-1234yf, or has been converted from R-12, you can purchase a recharge kit which will include the recommended refrigerant, dispensable from a pressurized can of approximately 12 ounces to 22 ounces and in most cases will contain a reusable recharge hose outfitted with.

Is R-22 Freon still available?

The U.S. government has placed restrictions on R22 and has issued the requirement that R22 refrigerant must be eliminated from use in cooling systems by the year 2020. R22 is being replaced by R-410A, a safer material which is the current, compliant standard refrigerant in air conditioning equipment.

Does my AC use Freon?

The good news is that new air conditioning systems made since 2010 no longer rely on Freon. Most newer AC units use a refrigerant called R410A, or Puron. This chemical is an HFC (hydrofluorocarbon), but has been shown not to harm the ozone and, since 2015, has become the standard for residential air conditioning.

Which is colder R12 or R134a?

R12 can blow 6 to 7 degrees cooler than R134a and is 15% more efficient. As a result, a perfectly functioning R12 system will blow colder and reduce temperatures faster than a system that was converted to R134a.

Is R12 refrigerant illegal?

R-12 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone. R-12 has many applications in refrigeration and air conditioning including large to mediums size chillers, automotive air conditioning, and as an aerosol propellant.

What happens if you put R134a in a R12 system?

R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn’t cool as well as R12. R12 systems used mineral oil, but unfortunately mineral oil doesn’t dissolve in R134a. So, along with R134a came a new oil: Polyalkylene Glycol—or PAG oil.
