Car Refrigerant: Limits of the Available Information
Rodi mentions a label under the bonnet showing R134a or R1234yf, but the available excerpt does not verify the information for a specific car.
Key points
A Rodi excerpt mentions a label under the bonnet showing R134a or R1234yf, but the available evidence does not confirm how to identify the refrigerant in a specific car.
What the excerpt says about the label
An excerpt from Rodi Motor Services says that many cars have a sticker in the engine compartment indicating whether the system uses R134a or R1234yf.
The excerpt is a limited secondary source: it attributes this information to Rodi but does not independently verify that the label is present or legible on any particular vehicle.

- R134a
- R1234yf
What can be concluded about a specific car
The specific suggestion in the excerpt is to look for the label, but the available evidence is not enough to confirm that it can identify the refrigerant in every car. It should therefore not be treated as a verified check for a particular vehicle.
The available excerpts also do not establish a reliable rule for inferring the refrigerant from the model or year, nor do they confirm another way to verify it. They provide insufficient grounds for quantifying environmental differences between R134a and R1234yf or confirming legal qualification requirements for working on the system.
