For a 1991 Pontiac Firebird, it's recommended to use a high-quality antifreeze that meets the specifications of the GM Dex-Cool coolant, which is an orange, extended-life formula. You can also use a traditional green ethylene glycol-based antifreeze, but ensure it's mixed according to the manufacturer's guidelines. Always check the owner’s manual for specific recommendations and dilution ratios before adding coolant.
