A 1998 Chevrolet Z71, like most vehicles from that era, used
R-134a refrigerant in its air conditioning system. However,
it's crucial to verify this by checking your vehicle's sticker or owner's manual. While R-134a was the standard, there's always a small chance of an exception.
Don't attempt to recharge your AC system yourself unless you have the proper equipment and training. Improper handling of refrigerants can be dangerous. Take your vehicle to a qualified mechanic for AC service.
