You will need a gauge and you would check the Pressure on the low side port. Take the PSI reading when the compressor is on and the clutch is engaged. The correct PSI is determined by the current ambient temperature and you can find a PSI chart on the website listed below.
probably r134a, but check with your manual.
R134a is a refrigerant gas
Can you mix r134a with r410a?
Yes, check with your local auto parts store.
It depends on the year but in most cases from 1993 and up they will use R134a freon but you can always check the VIN number with the dealer and remember that R134a freon will have larger service ports that R-12 freon............
It should be R134A. but if it is not, look under the hood and check around on the stickers on the frame and hood.
No, unless the a/c has been converted to r134a
R134a.
Chevy switched from R12 to R134a for the model year 1994. Your truck should be R134a.
newer vehicles, such as a 99 jeep, all use 134-A refrigerant.
The 134a plus just has PAG oil added already, so that you (theoretically) don't have to add it after adding the R134a.
