HI,

How many ounces? small can and large can dont tell me as there are at least 4 different sizes they are sold in. Look on the cans for the amount of ounces they hold and tell me that.

Chevy Mechanic: Eric, Automotive Repair Shop Manager replied 1 year ago

HI,

Ok, does yours have rear AC(makes a difference on capacity)?

Does the compressor engage?

If the compressor engages, what is the low side pressure reading with ac on in psi?

Hello, the capacity with aux cooling is 60oz so you're only half way there currently.

What type of noise is the compressor making? Do you have a gauge set to check high and low side pressure?

Ask Your Own Chevy Question
Customer reply replied 1 year ago
I have a gauge that came with the freeon and it's making a noise like its clicking on
Chevy Mechanic: K. Wiggins, ASE Certified Technician replied 1 year ago

Thanks the clutch clicking right now is normal while the system gets enough freon in it to keep from tripping the low pressure switch.

You will need to keep adding freon until the gauge for the low pressure read in correlation to the outside air temperature in the chart below.
