Hey guys, I was going to check the low side pressure to start diagnosing my air conditioner issue. When trying to connect the gauge set low side hose to the vehicle adapter, I realized the gauge set hose is internal thread and car side adapter is not threaded to accept the hose. Hope this makes sense? Just wondering what size quick disconnect adapter I need between the
hose and car?? High pressure side too? Thanks.....90' Convertible. If it matters, the car has the Sanden compressor.
I figured it out. Apparently the car had AC issues in the past and the system was filled with R134a refrigerant. The car side connection has a conversion adapter R12 to R134a fitting. Using my R134 manifold gauge set I was able to check the system pressure which was 90 psig (car cold). Good that there is no leak in the system but worse R134a killed my compressor (I assume)?
