ISSUE:
Some vehicles may exhibit air conditioner compressor failure due to an insufficient amount of refrigerant oil in the system.
ACTION:
Whenever service is required on the A/C system, add the appropriate refrigerant oil to the system. Refer to the following Service Procedure for details.
NOTE:
USE MOTORCRAFT YN-9 REFRIGERANT COMPRESSOR OIL FOR 1993 MODELS EQUIPPED WITH AN R-12 SYSTEM. FOR 1994 AND
LATER MODELS USING AN R-134a SYSTEM, USE MOTORCRAFT YN-12-B POLYALKYLENE GLYCOL (PAG) REFRIGERANT
COMPRESSOR OIL.
SERVICE PROCEDURE
1.
Remove all refrigerant from the A/C system using the appropriate R-12 or R-134a refrigerant recovery equipment following the manufacturer's
operating instructions.
2.
Service the A/C system as required.
3.
Check for Modification Label indicating additional refrigerant oil is already in place.
4.
If no label was found, add additional clean refrigerant oil (over and above the amount of oil required for the system being serviced). The oil may
be poured directly into the accumulator assembly or it may be injected by the refrigerant charging station, if so equipped.
5.
Recharge the A/C system using the appropriate refrigerant.
