Need some help in replacing an upper pressure gauge valve for 2001 V70 A/C unit. I see that it's leaking and just recently got the A/C recharged and after a day it was hot again.
I don't have a manual so can this valve be bought at Advance Auto / Autozone and can I replace it?

Thanks for help.

 

Welcome to the forum. You should post this up in the V70 section. I would help you but I am not sure myself.
