Which fitting to use when recharging AC? I understand the process, but am unsure which fitting to use when recharging. Is it the fitting on the line that goes to the condensor (right next to the radiator)? If you have a pic that would be great!! TIA!
Line from compressor to condenser is the high
pressure side, you can't push freon in there.
The fitting on the run from firewall to compressor
is your low side. If you have the cheapo fill kit
then you don't have to worry because the two
connectors are different diameter unlike older
R12 cars with all the same Schrader everywhere.
The only way you could screw up is if you had a
manifold gauge set hooked up and ignored the
pressure readings.
Be sure to fill with vapor (right side up) and not
liquid because there is no distance from port to
compressor. A tub of hot water will speed it up
once the can is open and starts to chill itself down.
