A/C vacuuming

["content22207 <brobertson@xxxx>" <brobertson@xxxx>]

Can do this even better: I use the engines themselves to vacuum my A/C
systems. A couple of brass fittings allow an R134 charging hose to
attach to 1/4 inch vacuum line. A spare nipple, 15 minutes of idle
time, and I'm ready for business. 25 year old A/C systems tend to
leak, some worse than others. Since a complete freon charge costs less
than $20, I don't fight them. While two of my Lincolns are
surprisingly tight, one leaks like a sieve. I've replaced all O rings
that are easily accessed; obscure ones aren't worth it. Problem could
be the hoses themselves. Whatever -- every summer I vacuum it down and
start with a new charge. Kind of like reverse winterization. Sucks up
about two more cans before fall. Small price to pay for cold air.
Since my D required another can in August, am pretty sure it will be
similar. Oh well...

themThere is a cheap alternative to having the shop service your air
conditioning system.It is a small "air vac" vacuum pump driven by air
from your air compressor.With this thing and a cheap set of gauges and
hoses which can be got at most auto parts stores you can serivice it
yourself.there are also kits available for flushing the system
yourself which arent to expensive.The air vac can pull enough vacuum
to evacute almost any system including the DeLoreans.Here is a link to
where you can pick up this handy
gadget-------.http://www.autotoolexpress.com/airvacforr12.html ----.It
cost around $60 dollars which is quite a deal compared to the
$300-$800 a regular vacuum pump costs. There are even shops who you
use this thing.The cost of the air vac and hoses/gauges altogether
shouldnt exceed $120.00 excluding shipping,but you should be able to
find a dealer near you.The people who generally carry the air vac on
hand sell to garages so it wont be a retail store.There is a set of
r134 fitting adapters which should be included with any gauge set you
buy make sure they are before you purchase it.I believe discount auto
parts has a set right behind the parts counter hanging on a display
rack near the o-rings for ac systems.If you have any further questions
email me off list.
