Hi all,
I am installing an A/C in my car that came from the factory with no a/c. I bought a brand new drier and I was wondering how do I remove the pressure connector that is on the drier?
Thanks!

 

The pressure switch just unscrews. A new drier has all the openings capped to keep moist air out. It is important to not uncap it until just before installing. Install the drier last. You may want to use an old drier for a static pressure test to make sure there are no big leaks, then install new drier, evacuate and charge.

 

Just curious, but wouldn't you want to re-test for leaks again once the new drier is installed?

Just to verify there is no leaks on those connections of the new drier?

Forgive me as I know next to nothing about AC.

 

At the drier connections there are only two or three possible leak points though, compared to installing a whole system with its many connections.
