Hello All
I just purchased a new Limo, and the air sucks. I put my gauges on it and
they are way high. The low side pushes 55, the high side is around 250.
The cooling fan works fine. I am almost positive that someone has
overcharged the system. Is thier any way to discharge a small amount of
freon without a vacuum pump? Into an empty can or something?
If it's R134a, it's the same stuff that's in those 'canned air' computer dusting
sprays. I wouldn't feel bad about venting a few ounces of R134 through the
schrader valve on the low side. If it's R12, I suppose you could hook up an
empty can to your gauge set, vacuum it out, and then put the can in a bucket of
ice and water and fill it from the low side of your gauge set. Freon should stop
flowing into the can in the bucket when the low side pressure equals the
pressure at which freon boils at 32-34 degrees F. Then close the valve on your
can tapper and plan on using that can fairly soon or taking it to a shop that
can recycle it.
Mitch.
