[DML] Re: AC Rubber tubing

["Jim Reeve" <dmc6960@xxxxxxxxx>]

I wouldn't bother replacing the O-rings on fittings you do not take
apart. They will be "sealed" in a similar manner that the old A/C
hoses have been over years of use.  The original factory R12 charge
was 2.5lbs, then reduced to 2.2lbs.  I would probably put around 2lbs
R134a in. This DMCNEWS tech article written by Dave Stragand has a
good overall procedure to follow for long-term sucess.

It also has good recommendations on refilling the compressor with new
oil. Dont forget to find the original leak, and good luck with everything!
