i am sure the kids will appreciate having working AC this summer.
the dodge minivan the grand marquis is replacing puked its compressor last
spring, and the thing was not worth the cost of a new compressor.
my 88 superduty uses 48 ounces for a full charge, so i figured it would be
about the same.
when in doubt, i usually put in 36 ounces, and then go from there, but this
is a 45k mile car so i want to do it properly.
she asked me to look at it, and we picked it up for $600 cause no one wants
an "old gas guzzler" that gets 20 mpg on the highway, and 14-around town
this thing is spotless, was owned and driven by an old woman that passed
away, and her son decided his 200k mile honda was a better car.
I would only charge by weight to 75% and then check the gauges -
make sure you don't overcharge. Your charging scale could be off
(I've only seen the old-school graduated liquid charging cylinders in
pictures) or they could put the wrong AC information sticker on the
radiator support or in the repair manuals, so you always 'trust but
If it has leaked down to zero or had an open leak you need to
replace the filter/drier, they get saturated very easily.
And if you see any signs of oil leaking out, check the oil level in
the compressor before recharging. They don't live long at all if you
run them without oil...
If you drive it conservatively 20/14 MPG isn't that bad, and is
achievable real world. (Leadfoots need not apply.) Take good care of
it, and it can be sold at a premium later to get something newer - or
drive it lots of years and squeeze all the value out.
