I'd assume R134a since R-12 was banned in 1994.
R-134a
How many onces for 134A refrigerant does GMC Sierra use?
134A
A 1997 GMC Jimmy uses R-134a as its refrigerant. This refrigerant replaced the older R-12 (Freon) due to environmental regulations. If you're servicing the air conditioning system, ensure to use R-134a to maintain its efficiency and comply with legal standards.
Using 134a plus refrigerant in a 2001 GMC Sonoma is not recommended. The vehicle's air conditioning system was designed for R-134a refrigerant, and adding a blend or "plus" refrigerant can potentially harm the system or lead to improper cooling. It's best to stick with the manufacturer-recommended refrigerant to ensure optimal performance and avoid damage. Always consult a professional if you're unsure about refrigerant compatibility.
The proper refrigerant for a 1998 GMC Suburban is R-134a. This refrigerant was commonly used in vehicles manufactured during that time period, replacing older R-12 refrigerants. When servicing the air conditioning system, it's important to ensure that the system is properly evacuated and recharged with the correct amount of R-134a for optimal performance.
