Lexus vehicles, including the Lexus RX 300, RX 350, LS 460, and ES 350, use R-134a refrigerant in their air conditioning systems. The capacity volume of R-134a refrigerant in the Lexus RX 300 is approximately 650g + or – 50g. It is important not to overcharge or undercharge the system, as it can cause damage or improper operation. If the system is low on refrigerant, it is recommended to have it evacuated and recharged by a professional.

How do I know which refrigerant my car uses?
The first place to look for this information is under the hood. Pop the hood and look for a label, which is usually white or bright yellow. On this it will either say “R-134a” or “R-1234yf,” and it may even say what the capacity is.
Is R-134a refrigerant illegal?
R134a is being phased out globally due to its high global warming potential. It’s been banned for new vehicle AC systems in the United States, and lower-GWP alternatives are taking its place across industries.
Does it matter what refrigerant you use in your car?
Please remember that using the wrong type of refrigerant for your system can create a hazard or cause serious damage so it is very important to get it right. Don’t worry though, as AC Avalanche recharge hoses can only work on systems of their respective type, eliminating the risk of using the wrong type.
What kind of refrigerant does a Lexus ES 350 take?
Since the Freon phaseout, car ACs have used a safer refrigerant called R-134a.
What cars use R134a refrigerant?
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. However, kinder is the key word.
What year did cars go to R-134a?
1994 – All new automotive A/C systems are required to run on R-134a refrigerant, rather than R-12.
Can R134a be replaced with R-1234yf?
While R-1234yf could be the perfect replacement for R-134a, there is one major challenge with this new technology. The R-1234yf is much more reactive than R-134a. On the positive side, this higher reactivity is why R-1234yf is so much more friendly to the environment.
What kind of Freon does Lexus use?
R134aLexus refrigerant filling quantities R134a and 1234yf
| Model | Year of manufacture | Freon type |
|---|---|---|
| Lexus CT 200h | 2010 – | R134a |
| Lexus GS300 (GRS/URZ) | 04.2005 – | R134a |
| Lexus GS 300 | 1997 – 2005 | R134a |
| Lexus IS 250 / 220d / 5.0F | 2005 – | R134a |
What is the difference between R134 and 1234YF?
As previously mentioned, R1234yf has a lower GWP compared to R134a. This means it has a lower potential to contribute to global warming when released into the atmosphere. According to the Environmental Protection Agency, R1234yf is more energy-efficient compared to R134a.
Can I use R-134a in a R-1234yf system?
Still, the answer is an emphatic, “No.” Not only would a retrofit of this type negate the environmental benefits of R-1234yf, but it would also be a violation of Federal Law under Section 203 of the Clean Air Act: “tampering” with a vehicle’s emissions control device.
