On my air condtioner (see sig) what line is the low pressure side and which one is the high pressure side? Which one do you do you hook up to for filling the A/C refridgerant? I see 2 fittings one up by the air inake and one by the radiator/condenser. First time trying to do it on my own. Thanks for any info.

 

On mine, the caps have a "H" for high and "L" for low. I believe the high was at the front by the radiator and the low was back by the air cleaner.

Correct me if Im wrong, but I believe thats right.

Have a good one.

 

Thanks for the info Howy, going to take a look and see what I can find.

 

The smaller fitting/cap is the low side and that is the side you charge.
