When did Ford stop using R12 refrigerant?
As a seasoned auto service provider, I often encounter questions about refrigerants and their impact on vehicle performance. One common query is regarding the transition from R12 refrigerant, a substance that was widely used in automotive air conditioning systems. Understanding when Ford and other manufacturers phased out R12 can help car owners maintain their vehicles more effectively.
The Shift from R12 to R134a
Ford, like many other automakers, transitioned away from R12 refrigerant due to environmental concerns. R12, also known as dichlorodifluoromethane, was phased out because it contributes to ozone depletion. The Montreal Protocol, an international treaty designed to protect the ozone layer, led to the gradual elimination of R12 production and use.
Timeline of the Transition
Ford officially stopped using R12 refrigerant in its vehicles starting in the early 1990s. Here’s a brief timeline of the transition:
- 1987: The U.S. government began regulating the production of R12 due to its environmental impact.
- 1992: Ford began to phase out R12 in favor of R134a, a more environmentally friendly refrigerant.
- 1994: By this year, most Ford vehicles were equipped with R134a systems, marking a significant shift in the industry.
Why the Change Matters
Understanding the refrigerant used in your vehicle is crucial for maintenance and repair. R134a is less harmful to the environment and is more readily available than R12, which is now banned in many places. If you own an older Ford vehicle that still uses R12, it’s important to consider retrofitting your system to accommodate R134a to ensure compliance with current regulations and to maintain optimal performance.
Conclusion
In summary, Ford stopped using R12 refrigerant in the early 1990s, transitioning to R134a to comply with environmental regulations. This change not only reflects a commitment to sustainability but also impacts how vehicle owners maintain their air conditioning systems.

Frequently Asked Questions
When was R134a banned?
The AIM Act is a Federal nationwide rule phasing out the use of global warming materials. As part of that effort, EPA is now banning the use of 134a in aerosol products as of 1/1/2025. There are excepted products that are allowed to use 134a until 1/1/2028.
Is R12 colder than R-134a?
The evaporator exit superheat was maintained constant at 13.5 F (7.5"C) for all tests. The experimental results show that for almost all test conditions the R·134a operates with greater COP and cooling capacity.
What year did Ford stop using R12?
So carmakers were mandated to stop using R12 after the 1994 model year. One current replacement refrigerant is R134a, which serves the same purpose as Freon but is less harmful to the environment.
When was R12 banned in US?
History of the Freon Ban
It was banned from all new cars sold in the country beginning in 1995 and stopped being used in new air conditioning systems, heat pumps, and refrigeration systems in 2010. With the 2020 ban, no additional Freon could be produced or imported.
When was R-134a banned?
The AIM Act is a Federal nationwide rule phasing out the use of global warming materials. As part of that effort, EPA is now banning the use of 134a in aerosol products as of 1/1/2025. There are excepted products that are allowed to use 134a until 1/1/2028.
How long will R134a be available?
This group of synthetic refrigerants is not subject to a ban on use. This means that installations using R134a, R407C and R410A can simply be refilled after 2030. However, there will be significantly less synthetic refrigerant available in the future due to production limitations.
What would happen if I put R-134a in a R12 system?
R134a systems work at higher discharge-side pressures than R12 systems, which could lead to compressor seals leaks. Additionally, since R134a is composed of much smaller molecules, it has a greater chance of leaking from an R12 system.
Is R12 toxic to humans?
EMERGENCY OVERVIEW: Colorless, volatile liquid with ethereal and faint sweetish odor. Non-flammable material. Overexposure may cause dizziness and loss of concentration. At higher levels, CNS depression and cardiac arrhythmia may result from exposure.
What year did they switch from R12 to R-134a?
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. However, the use of R-12 in existing vehicles continued for several years, and some older vehicles may still have R-12 systems today.
What was the last year of R12?
For many years, R12 was the automotive refrigerant standard. It was effective and cheap. However, scientists quickly discovered its sinister secret: It was partially responsible for the rapidly-depleting ozone layer. In 1994, it was banned from all new cars sold in the US.
