RE: [DML] Re: AC clutch running continuously

David, 
What seat of the pants information are you coming up with about converting
old NOS 30 year old parts to New R134 systems.
I can't believe your saying this. Man, what are you trying to do to all the
people on the chat groups about updating the AC system. Don't you think the
new Goodyear hoses I build will not hold the pressure? Do you think the
compressor made for R134 won't perform?  Do you think the evaporators and
condensers won't work.
You need to talk to engineers a little more before you try to put out
information about not converting the system over. I'll give you the experts
phone numbers at Sanden if you have any doubt.
Do I need to start selling fire extinguishers again because if you take the
gas cap off the car may catch on fire.

The A/C system in the Delorean was not designed for the use of -134.
It can work but you will run higher pressures, hotter tempertures, and
a loss of capacity. R-12 is NOT outlawed. It can no longer be
manufactured or used in newer vehicles. It CAN be recycled and used in
vehicles that were origionally designed for it's use. It is supposed
to be handled only by licensed people but it is NOT illegal. I also
agree that there are better alternatives but more because of
economics. R-414B is a drop-in replacement that is cheaper and more
environmentally friendly but R-12 is still the "best" as long as it is
still available. To switch to -134 the hoses, every seal, the
accumulator, and all of the oil must be replaced. A big, expensive job.
