I'm Awesome
Already replaced the low side valve, but noticed the high side valve hisses when I take the cap off with the truck off. It doesn't have the same shrader valve as the low side, and I saw there's a replacement part for it, but wondering A) is it supposed to hiss like this (guessing no) B) is there a way to replace it without evacuating the system.
