Freon R-134a (tetrafluoroethane) has a boiling point of approximately -26.3 degrees Celsius (-15.3 degrees Fahrenheit) at atmospheric pressure. This characteristic makes it effective as a refrigerant in various cooling applications. Its low boiling point allows it to evaporate easily, facilitating heat absorption in refrigeration systems.
R134 .... IS freon.

THERE IS NO FREON IN A 98 IT IS R134
They should never be mixed.
1993-95 for most.

With the A/C running Full-Blast @ Lowest Temp., You adjust R134 gauge according to Ambient Temp., & then add required amount of R134 until the black dial falls into the center of the Red 'Ambient Temp Zone'. Let engine run for 20 to 40 minutes with A/C remaining on Full Blast.
Should be R134 if it is 1993 or newer if older should be converted to R134
Nope, it uses R134.
