Re: Charging my Air Conditioner -- Thanks

I bought a double size can of juice that included a hose and guage. The
directions were printed on the can, and they said to juice the system up to
about 50 psi for the current temp at my house. Completely counter to the
luck that runs in my family, the can was empty just as the spec was met.

As soon as the pressure came back, the compressor clutch kicked on and
remained on, and the cabin air temp hovered at about 50°F.

What's illegal?

Another trick is to lay it on the engine valve cover.

Watch the system over the next few days/weeks Jeff, check the connections,
especially where the metal ends are made onto the hoses, and the front of
the compressor clutch for any oily leaks.

Be cool, (pun intended)
