The high-pressure valve on the air conditioner of my 01 Grand Prix started leaking and needs to be replaced. Unfortunately the Schrader valve is not replaceable on the high-pressure side. The entire Evaporator Tube Assembly must be replaced. I got the part (Amazon) and started to disassemble but can't seem to figure out how to pull it out without pulling the engine first. There's a coupling that is located under the break booster but I can't get any tool I own on it to take it apart. Has anyone ever tackled this job before? Need help.
Thanks.
