This information replaces the air conditioning refrigerant specifications on page 190 of the 1994 Pontiac Sunbird
Owner's Manual.
If your Sunbird has air conditioning, the system could be filled with R-12 or R-134a refrigerant. These refrigerants
are not interchangeable. If service is required, please refer to the refrigerant charge label under the hood for
refrigerant charge type and quantity.
