Retrofitting
SYSTEM CONVERSIONWHEN TO RETROFIT
As long as R-12 is available, it should be used to service a vehicle with an R-12 system.
When R-12 supplies are unavailable, the customers may be willing to pay for a retrofit.
STANDARD RETROFIT
To achieve the most effective system retrofit, follow the instructions in Service Information Bulletin # 64 O1 95 (4179). Retrofit kits have been developed for the E31, E32, E34, and E36 models, to provide comparable system performance. The kits include a new receiver/dryer; hoses, service fitting, refrigerant controls, and other parts.
