hey guys so have you ever filled your GM AC with Freon to only find that it's leaking. well here's why. apparently GM has their high pressure valve in a weird way that once the valve is pressed down, it goes bad. all GM or Chevy high pressure AC valves do this apparently. it's super easy to replace these high pressure valves. use a 16 mm wrench and a vice grips and twist. it's that easy.
