Are you absolutely sure it uses R-12? You might want to look again. I've
bought and sold many Taurus cars (that were 90's and up)- and never seen
one use R-12.
The new O-rings (R-134a) should work fine, in my experience anyway.
Why not just switch it over to R-134a? All you have to buy is the switch
over adaptors at your local part store. Whenever you make up your mine,
make sure you add the correct type of compressor oil.
Yes, a 93 uses R12. Mine does. What happened to the air to cause it to fail?
As far as the o rings go, just take the old ones off down to the auto parts
store and have them matched up. Should not be a problem.
I think the Green ones are compatible with R12 and mineral oil.
Those compression fittings can be a pain in the ass to get apart if there
original and never been taken apart. I assume you bought the special tool
to pop the springs in the fittings?
Mine is still on r12. But if it died, i think i would convert it to 134.
To do it right, you would need to change the compressor as well as the
accumulator with the drier in it. I helped a guy on a mid 80's town car
do a cheap R134 conversion with just the orings replaced. SO far so good.
But that's not the kosher way to do it. ANd you need a vacuum pump and a
thanks bob, yes i have a vacuum pump-built it about 30 yrs. ago from an
old ref. that was laying in the dump.. took the comp. out and put a
fitting on it and it works pretty good.. kinda slow, but i have all the
time in the world... alot better than buying one of those $300 pumps to
do a job that might be done about 4 times in a lifetime.... and thanks
for the other info on the O-rings....
I agree.... saves hassle later on, the conversion works well, though you
might want to get the r-134 orifice while you are at it.
And you can sell the R12 to a mechanic or refrig tech and recover all your
the orifice is in the hose, comes with the accumualtor on this car..
they do sell a kit with a lengh of tubing with the orifice in it and you
cut your tubing line and attach it there... dont know if they have a
seperate one for the R134-r freon???? how about flushing the system???
i got to replace the compressor and the accumulator with the hose on
it.. so how do i flush this out??? with the system off or with the old
one on or the new one on????? and what do i use to flush it with????
i got the R-12 gauages, vacuum pump and the plastic clip around tubing
to take off the parts(hoses, etc.) got an orifice removal tool...well it
worked in the 70-80's and did i good job....got the shop manual from
Helm... and it looks like the orifice is fixed in the tubing.. and when
you need a new orifice you have to cut the metal tubing out and put in a
new section as a kit with the orifice in it..... thanks for a reply...
If you want to replace the expansion valve, on some fords you buy a new
hose. Others it is in the line and replacable. If it is in metal tubing it
might be replaceable. It will be near a fitting and you just pull it out.
You never have to cut it apart. If need be you buy a new high pressure line.
You can buy flush. try to flush the condensor and evaperator the best you
