ANY AUTOMOTIVE AC EXPERTS OUT THERE? I'VE GOT PROBLEMS..........

Evacuate it down, put two 12 oz. cans in the system from the "Low" pressure side only. Close the freon manifold valves, roll the compressor over by hand to make sure the AC pump is not hydraulic locked. Then start it up and finish installing the last 4 oz. of R 134 freon by opening the low pressure side manifold valve.

Put a meat thermometer in the interior vents with the AC full on, when the cool temp gets to 60° you know you are getting close ro full.

Keep adding the final freon til the temp out the vent gets to 50° F. Then you are full.

On a cool day you can submerge the frosty freon can into an ice cream pail of hot water, this helps to empty the can an push it into the system.

1 can 12 oz
1/2 can 6 oz.
1/4 can 3 oz.

24 oz + 3 oz = 27 oz.
Think you can figure it out if you dont have a scale, and go by the thermometer.
