I have a 97 1500 5.9l

I just installed a new ac comp, is there a diy way to remove the air from the system? also where does this part go?

 

To remove air takes a vacuum pump. That piece is the orifice tube (filter). Mine is at the condensor.

Make sure you add oil.

 

cool thanks for the help!

 

you can try putting your feon in through the low pressure side while keeping the high preassure side open till you have about half a can in then fill to your low preassure side to specs with the system on.

 

Not if you want it to work correctly. As soon as the refrigerant gets to high side (meaning pressure after compressor) it will blow out here. Air will still not be evacuated from the system. Also, any oli added will blow out as well. And the amount of air that is still in the system will never let the system be near acceptable specs. Specsa are .... air is removed by evacuation....

 

Not to mention that evacuation also has the side benefit of removing any moisture in the system.
