Fox Approach to getting AC back working

adk · May 23, 2023

I have a '90 that has been off the road for a number of years. What route have those who have chosen to keep your AC operational taken? Upgrade just the fittings to accommodate R134, buy the whole conversion kit from LMR, try to recharge with R12 cans from eBay, other methods?

What’s the state of the ac system now? Open? Hasn’t worked in 20 years? Partially missing?

adk · May 23, 2023

It is intact and closed. When I turn on the AC the compressor repeatedly engages for about 2 seconds, then disengages for about 2 seconds before reengaging for 2 seconds. Searching the Internet it appears this is a symptom of a system low on refrigerant. I would be interested on approaches that have worked well for others (attempt to find/add R12, convert fittings to R134 and recharge with R134, other ideas that worked for you).

They are no longer available as of this year. Ebay isn't allowing R12 Freon to be sold there anymore.... they remove any listings and are blocking all sales. Unfortunately.

They still sneak in there. Buy it before I add more to my stockpile.

Sounds like it is low. Are you 100% sure it’s still filled with R12? If the compressor is still engaging it’s probably half filled. You’d need at least 2 cans of eBay R12. About $40 or so a can.

If you don’t go that route, flush the entire system with solvent and start from scratch. Replace the orifice tube, replace the condenser (modern units are superior to the old serpentine style) and use R12 /r134 compatible oil and charge with R134a

My system was a from-scratch system and I used R12. In hindsight, I should have sold off my supply and gone R134a

No shop will touch the system if there is R12 in it. All their equipment is 134a or 1234 and they won’t cross contaminate. I doubt you’ll find someone with an R12 recovery machine but there are creative ways to discharge it into a vacuum recovery tank.

I use ES12a it is comparable with r12/134a. And can be introduced without vaccum. You will need to use 134a valve adapters though.
I've run it for years in my daily driven fox, and I l ive on the surface of the sun(nevada) up to 118 in summertime. Do your research you'll be pleased.

Missed it. The posting was already removed.

Act quick! Ebay will remove the listing once they become aware of it.

Someone grabbed it. Hopefully someone here. That price is par for the course for R12. $40/can or so.

I have this plus some cans...so i'm good for a while.

85GTStangGuy · May 23, 2023

That was fast.

Myself, I've been stocking up for the past year-and-a-half from ebay. Glad I didn't wait.

85GTStangGuy · May 24, 2023

Only 1 can of R12, but better than zero....

My FOMO was kicking in and then I realized that I've already converted.

Mustang5L5 · May 24, 2023

I threw a bid on that (not winning) just to see if that thing gets pulled before the 9-day auction is up. I think it will.

BIN seems to be the best way to get them.

A few years back, sellers were asking for copies of the license. Then they started asking for a waiver saying you were buying the cans to hand to a tech. Last few years its been a free-for-all and no license or waiver. Probably why they are pulling auctions.

85GTStangGuy · May 24, 2023

BIN???

Edit - nvm. Buy it now.

You can find R12 locally just about everywhere these days as the demand is gone
I just bought another 30 lb cylinder for 300 bucks
Yours just needs a squirt adk
Find a can in your area and add some until the pressure is about 30 lbs on the low side and you should be good

Go with R134. You’ll have to pull a vacuum, then charge.

manicmechanic007 · May 27, 2023

Fitting kit and ester oil?
Lesser performance
Stay with 12 if not empty

Mustang5L5 · May 28, 2023

I kinda agree. If that’s an r12 system that’s low? Easiest thing is to just add a squirt of r12 and call it a day.

Noobz347 · May 28, 2023

Then check it for leaks the day after.
