What ac coolant does a 1998 Chevy blazer use?
The 1998 Chevy Blazer uses R-134a refrigerant. However, it's crucial to never attempt to add refrigerant yourself. Low refrigerant is often a symptom of a leak, and adding refrigerant without fixing the leak is both inefficient and potentially damaging to the system. Take your Blazer to a qualified mechanic for proper diagnosis and repair.
