This TSB article is being republished in its entirety to include the latest level parts.

ISSUE 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.
ACTION 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.

NOTE:
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.

NOTE:
HFC-134a IS THE ONLY CFC-12 (R-12) REPLACEMENT REFRIGERANT APPROVED BY FORD MOTOR COMPANY.

Detailed service procedure instructions are provided with each retrofit kit.

Heading definitions for lettered columns found in the following charts:

  • A = Condenser
  • B = Compressor
  • C = Accumulator
  • D = Engine Fan and Clutch
  • E = Electric Fan
  • F = Air Deflectors
  • G = Control Module
  • H = Suction Hose

  • M = Flushing Procedures

*****Miscellaneous kit items for all systems include: Cycling Pressure Switch (CPS), CPS adapter, Refrigerant Containment Switch (RCS), RCS wiring harness assembly, RCS adapter, low side service port adapter, high side charge port adapter, PAG oil, and retrofit label.

*Suggested Retail Price (SRP) DOES NOT include the cost of refrigerant or A/C repairs necessary.

***Approximate installation times include the addition of refrigerant and system flushing.

****For L-Series vehicles built prior to the 1991 model year (vehicles built through December, 1991), replace the receiver/drier with an R-134a compatible receiver/drier. Refer to the following Compatibility Chart.
