||This TSB article announces the Ford OEM air conditioning retrofit kit availability. Retrofit kits convert R-12 air conditioning systems to operate on R-134a refrigerant. All Ford kits are designed for specific vehicles and offer equivalent performance to the original R-12 system.
||When a consumer inquires about a retrofit kit, refer to the following Charts to see if a kit is available from Ford. If the vehicle is not listed, a kit is not available from Ford.
The Chart identifies
which components are included in each kit for the purpose of providing repair
estimates. Ford recommends the use of R-12 in R-12 A/C systems as long as it
is available and cheaper then retrofitting to R-134a. Ford does not recommend
the use of any refrigerant other than R-134a or R-12.
THE REMOVAL OF MINERAL OIL DURING THE RETROFIT IS NOT REQUIRED UNLESS NOTED
UNDER THE "FLUSHING PROCEDURE" COLUMN (M) IN THE CHARTS FOUND IN
THIS TSB ARTICLE. THE POLYALKYLENE GLYCOL (PAG), SUPPLIED IN EACH KIT, MUST
BE ADDED WITH R-134a. PAG OIL, MINERAL OIL AND R-134a CAN BE MIXED TOGETHER
IN THE A/C SYSTEM WITHOUT CAUSING DAMAGE.
HFC-134a IS THE ONLY CFC-12 (R-12) REPLACEMENT REFRIGERANT APPROVED BY FORD
