The 1991 Toyota Previa uses R-12 refrigerant for its air conditioning system. However, due to environmental regulations, R-12 is no longer produced, so many owners convert their systems to use R-134a refrigerant instead. If converting, it’s important to ensure that the system is properly retrofitted to accommodate the different properties of R-134a. Always consult a professional for the best approach to refrigerant replacement.
