I'm trying to replace the Valve Cover Gasket on my Trailblazer. Problem is, in still somewhat new to mechanics and I don't know how to or where to discharge the AC system At. If someone can give some pointers, that'd be much appreciated.
Yeah I have a Vortex 4200. I kinda just figure that out.Assuming you have a 4.2 you don't have to discharge the A/C at all
