Air Conditioning problem
1986 Dodge Truck V8 Four Wheel Drive Automatic 168000 miles
Air conditioning systems in older cars and trucks use R12 refrigerant. If charging an evacuated system there is usually a specifed weight of (R12) freon to be added to the system. My questions concern changing over to the R134a refrigerant. Once seals and new oil have been added to a "cleaned" system, is the weight specification for the R134a refrigerant the same as specified for the R12? And if not, is there a translation table table avaailable for this purpose? Also, it seems that systems using the R134a refrigerant must utilize higher pressures to achieve the same level of cooling that was attained by the R12. Since an R12 to R134a conversion is using the same components, how less efficient is a system that uses R134a with R12 era components?
have the same problem?
