This TSB article is being republished in its entirety to list Environmental Protection Agency (EPA) reviewed A/C substitutes for R-12 refrigerant.
A number of manufacturers are producing refrigerant products which are described as being direct replacements for refrigerant R-12.
If service is required, use only new or of known quality recycled refrigerant R-12. Ford Motor Company has approved R-134a as the only refrigerant substitute for R-12.
USING ANY UNAUTHORIZED SUBSTITUTE REFRIGERANT FOR R-12 MAY RESULT IN SEVERE DAMAGE TO THE A/C SYSTEM COMPONENTS.
INFORMATION FROM THE EPA
This information has been taken from EPA documents to address Ford specific applications and recommendations. Further EPA information on ozone-depleting substances and regulations regarding its handling can be found on the Internet at World Wide Web site: http://www.epa.gov/ozone/
In 1994, EPA established the Significant New Alternatives Policy (SNAP) program to review alternatives to ozone-depleting susbstances like R-12. EPA examines new substitutes for their ozone depleting, global warming, flammability, and toxicity characteristics. The SNAP process does not test these substitutes for A/C system compatibility, reliability, durability, or performance.
Under the SNAP rule, each new refrigerant must be used in accordance with the following conditions:
Unique Fittings - Each new refrigerant must be used with a unique set of fittings to prevent the accidental mixing of different refrigerants.
Unique Equipment - Each refrigerant must have dedicated recovery/recycling equipment for that refrigerant.
Labels - Whether a vehicle is originally designed to use a new refrigerant or is retrofitted, the technician must apply a detailed label giving specific information about the alternative. This label covers up information about the old refrigerant and provides valuable details on the alternative and how it was used. The technician is required to fill in their name, company performing the retrofit, address and the date retrofitted.
Remove Original Refrigerant - The original R-12 must be removed from the system prior to charging with the new refrigerant. This will guarantee that the largest amount of clean R-12 is available for use in vehicles that still need it.
A summary of the refrigerants reviewed under EPA's SNAP program for use in motor vehicle air conditioning systems is in the following table.
Composition claimed as confidential business information
Flammable blend of hydrocarbons; insuffcient data to demonstrate safety
Contains CFC-12, which is inappropriate in a CFC-12 substitute
Flammable blend of hydrocarbons; insufficient data to demonstrate safety
Contains a perfluorocarbon, which has extremely high global warming potential and lifetime
(1) R-401A (made by DuPont), R-401B (DuPont), R-409A (Elf Atochem), Care 30 (Calor Gas), Adak-29/Adak-12 (TACIP International) and ES-12R (Intervest) have not been submitted for review in motor vehicle air conditioning, and it is therefore illegal to use them in such systems.
(2) See article for details on legality of use according to Status:
ASU = acceptable subject to fittings, labeling, and no drop-in use conditions
P = proposed acceptable subject to use conditions; open to public comment so decision is not final
UNA = unacceptable; illegal for use as CFC-12 subtitutes in motor vehicle air conditioners
(3) Freezone contains 2% of a lubricant
(4) Additional use condition: MUST BE USED WITH BARRIER HOSES
