What freon does Chevy use?
Chevrolet vehicles typically use R-134a refrigerant, also known as HFC-134a, in their air conditioning systems. This refrigerant has been the standard for most automotive manufacturers since the phase-out of the older R-12 (Freon) in the mid-1990s.
Understanding Automotive Refrigerants
Refrigerants are essential components of a vehicle's air conditioning system, responsible for absorbing and releasing heat to provide cooling. Over the years, the automotive industry has transitioned through different refrigerant types due to environmental concerns and regulatory changes.
- R-12 (Freon): This was the predominant refrigerant used in vehicles prior to the 1990s. However, it was found to be harmful to the ozone layer and was phased out under the Montreal Protocol.
- R-134a: This refrigerant became the standard replacement for R-12 in the mid-1990s. It is a hydrofluorocarbon (HFC) that does not deplete the ozone layer, making it a more environmentally friendly option.
- R-1234yf: More recently, some automakers have started transitioning to this newer refrigerant, which has an even lower global warming potential compared to R-134a.
Chevrolet, like many other major automotive brands, has primarily used R-134a in its vehicles since the phase-out of R-12.
Chevy's Use of R-134a Refrigerant
The use of R-134a refrigerant in Chevrolet vehicles is well-documented. 1 This refrigerant is compatible with the air conditioning systems designed for Chevy models, ensuring proper cooling and efficient operation. 2
It's important to note that while R-134a is the standard refrigerant used in Chevy vehicles, some newer models may transition to the more environmentally friendly R-1234yf refrigerant in the future, as the industry continues to evolve and adapt to changing regulations and environmental concerns.
What kind of Freon does a 2017 Chevy Silverado 5.3 take?

Can I use 1234yf instead of 134a?
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.
When did GM switch to R-1234yf?
The first vehicle on the U.S. market with R-1234yf was the 2013/14 Cadillac XTS, which came out some nine months ago—a very low-volume model. It was followed by the higher volume ATS, which had to go back to R-134a a month after introduction because of noise and vibration issues.
What vehicles use R-134a 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.
Can you mix R-1234yf with R-134a?
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.
Is R-134a phased out?
The commonly used synthetic refrigerants such as R134a, R407C and R410A have a GWP value higher than 2,500. As a result, their production is being phased out.
Is it illegal to put 134a in a 1234yf system?
The refrigerant R134a in an automobile air-conditioning system provided for R1234yf is considered an illegal substance according to Directive 2006/40/EC. This is punishable by a fine and in particularly blatant cases even by imprisonment.
Can you mix R-1234yf with R134a?
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.
What year did cars switch to R-134a?
In fact, some automakers had already started using R-134a in their vehicles as early as 1992, two years before the U.S. ban on R-12 in new vehicles. So to answer your question, the conversion from R-12 to R-134a began in the late 1980s, and many automakers had already made the switch to R-134a by the early 1990s.
Is R-1234yf a drop-in replacement for R-134a?
The cooling capacity of R1234yf used as a drop-in replacement in a R134a refrigerant facility is about 9% lower than that presented by R134a in the test range. This difference in the values of cooling capacity obtained with both refrigerants decreases when the condensing temperature increases and when an IHX is used.
