A/C - Use of Alternate Refrigerants
NO.: 92-T-43
DATE: September, 1992
GROUP: HVAC
CORP NO.: 231205R
SUBJECT:
Information on the Use of Alternate Refrigerants in CFC 12 Refrigerant Mobile Air Conditioners
MODELS AFFECTED:
All 1991-1993 Saturns equipped with air conditioning.
A number of inquiries have been received concerning the use of "Alternate Refrigerants" as a replacement for R-12 refrigerant in Saturn air conditioning
systems.
PURPOSE:
Regardless of any advertised claims, there are currently no substitutes for refrigerant R-12 approved by Saturn. At the present time, only new or recycled
R-12 is approved for use in Saturn R-12 air conditioning systems.
Based on studies performed to date, the use of alternate refrigerants in R-12 air conditioning systems may result in higher system pressures. System
performance may also be affected.
Service equipment manufacturers have indicated that cross-contaminating R-12 recovery/recycling equipment with alternate refrigerants may damage the
equipment. Saturn supports the Society of Automotive Engineers (SAE) recommended service procedures for recovery and recycling of R-12. The use of
known alternate refrigerants without proper service practices for identifying vehicle systems containing these alternate refrigerants, and dedicated
recovery equipment to service those vehicles, will contaminate the recycled supply of R-12 refrigerant. Contamination of the recycled R-12 refrigerant
makes the refrigerant unusable for recharging air conditioning systems and could jeopardize the recycling program.
At the present time, Saturn has not approved any alternate refrigerant for R-12, in R-12 air conditioning systems. Therefore, R-12 systems should
continue to be serviced with new or recycled R-12 only.
