Chrysler may switch to another coolant in the future, “but right now 134a is the best one,” said Vines. Automakers say that HFC generally does not work as well as R-12.

HFC-134a is the alternative refrigerant of choice to replace CFC-12 in many medium- and high-temperature stationary refrigeration and air conditioning applications. However, R-134a is not a direct ...

A pressure-temperature relationship (PT) check is not a recommended procedure to determine if a refrigerant cylinder is contaminated, as a contaminated system that contains a refrigerant blend could ...

The actual word we should be using is refrigerant. R-12 refrigerant has not been available for many years. R-134a and R-1234yf are standard with the latter being used in all new vehicles.

It eventually will likely replace R-134a, commonly used today as the A/C refrigerant in cars, trucks, and other vehicles.
