Here’s a photo of one of the first R-1234yf labels you’ll see on the street. This one’s stuck on a 2013 Cadillac XTS4, the first GM car to use the new refrigerant.
What’s the meaning of all those symbols and nomenclature on the label?
Let’s start at the bottom left, and work our way around the label:
- Technicians must be certified;
- The refrigerant is flammable;
- Caution must be taken when working on the system;
- Don’t place hands in the vicinity of the condenser fan; the fan can start automatically;
- Make sure you are educated about it before attempting to work on the system;
- The refrigerant used in the system is R-1234yf; the amount is 0.620 kilograms (that’s about 1.37 pounds, or about one pound, six ounces for our metrically-challenged readers);
- PAG oil is the type used in the system;
- SAE J639: SAE standard J639, “Safety Standards for Motor Vehicle Refrigerant Vapor Compressions Systems,” applies;
- SAE J2842: SAE standard J2842, “R-1234yf and R744 Design Criteria and Certification for OEM Mobile Air Conditioning Evaporator and Service Replacements,” applies;
- SAE J2845: SAE standard J2845, “R-1234yf [HFO-1234yf] and R-744 Technician Training for Service and Containment of Refrigerants Used in Mobile A/C Systems,” applies
So now you know. Look for similar labels on other new GM vehicles in the future. Certain other car makers are also scheduled to start using R-1234yf. Keep an eye on this space, and we’ll try to let you know who, and when.

When having your mobile A/C system professionally serviced, insist on proper repair procedures and quality replacement parts. Insist on recovery and recycling so that refrigerant can be reused and not released into the atmosphere.
