Can someone go into a little more detail as to what is involved with
changing the o-rings, flushing the lines and compressor oil, and changing
the drier. Is it easy/hard? Can be done in an afternoon?
In the archives, someone said we would need to change the lines because they
are the wrong type and will leak. True?
Also in the archives someone said that the shop should extract the old R-12
for free because they are getting a free supply of R-12. When I went to
Pep-Boys they told me it would cost $50.00. Do shops still do it for free?
Is it unreasonable to pay $50.00? In fact, they said the $50.00 is just to
hookup the equipment. If I need a charge I would only need to pay for the
freon after the $50 hookup charge.
Thanks,
Paul Borghese
