2011 LOW A/C CHARGE diagnosing

This is part 1 of 3 parts.

For having only 90 g of refrigerant in the system it actually cooled pretty well and fool a few people.

In part 2 explain a little bit of the recovery procedure and going into the vacuum procedure. With the refrigerant recovery equipment that I use if you notice up on the gauges unlike those big stupid machines that they sell to automotive shops this particular refrigerant recovery unit I can pull all the way down into the micron level of vacuum ensuring complete refrigerant removal before even using a vacuum pump.

In part 3 pay particular attention to the superheat and sub cooling difference between part one and part three.

For those individuals who believe in sight glass if I add another 100g of refrigerant to the system the site glass goes clear. But yet it would be about half empty or half full whatever your terminology you would use.
Do not use site glass do not use pressures to determine if a refrigerant system is full or low.

 

I know in the video I said 2004 it’s actually a 2011 gen 3.
