The 1986 El Camino originally used R-12 refrigerant. However, due to environmental regulations, many owners have converted their systems to R-134a. If you're considering this conversion, ensure that the system is properly retrofitted to accommodate the different properties of R-134a, including replacing the receiver-drier and using the appropriate oil. Always consult a professional for the best results.
