What kind of freon does highlander 2002 use?

The 2002 Toyota Highlander uses R-134a refrigerant for its air conditioning system. This type of refrigerant was commonly used in vehicles manufactured before 2010, as it is less harmful to the ozone layer compared to older refrigerants like R-12. If you're servicing the air conditioning system, it's important to use the correct type to ensure optimal performance.
