Air conditioning system for 1983 GLT[ALL/1998] posted by Dennis Hayes on

I have seen refrigerant conversion kits at various auto parts establishments.
Can the ac on an r-12 system for an 1983 Volvo be converted to 134A without
changing the compressor and/or other components? I would appreciate any help.
I'm also having problems with my odometer. The speedometer works fine but the
odometer just quit functioning. Can anyone give me some pointers? Thanks

I have two speedos with the same problem. Probably the odometer needs a rebuild, which costs about $95.00 at my local shop. Seems that some of the numbers get sticky, which causes a small gear on a shaft to break. If you just replace the small gear, the underlying cause will make the new gear break in about 5k.
Any good speedo shop should know about these units, as they are only good for about 150 k according to my source, and are a constant source of income for them. While you can do the work yourself, and save money, you need to buy the right gear. I've heard of some sources. One even has an internet site. Somewhere in the Dallas area, I think.

I appreciate the help on the speedometer. I will check it out this week. But I have not heard anything about the air conditioner. Do I have to change the compressor and/or other components or is the R-12 system compatible with R-134A?

Dennis,
The AC system in the 83 is designed for R12 and will need the $200 + kit to comply. I have heard of folks seeking out 91-93 240's in Salvage and Junque yards for the R134a parts.
One usual source in NC charges a premium for the post 90 AC units!
(I probably would too but I don't own a salvage yard).
My suggestion is to find a donor in a yard or fix/recharge the old one. It has been posted here that the El Cheapo kits only contain part of the needed kit and that the dryer must be replaced as do the seals, o rings, etc. the system purged
and recharges with R134A with the appropriate NEW lubricant. I also understand that older hoses are more apt to allow the R134a to pass thru the sidewalls of the hose.(There's a tech term for this but it's Sunday and I'm tired).
Advice-unless it's DFM fix it w/ R12. If it's shot try finding a donor unit and swap 'em out. If the system is dead anyway it ain't that hard and the hoses can be replicated at a good hydraulic shop, just cut off at the firewall and bring both halves in and they'll be able to make them up just like new.
If you see a donor with the AC Condenser cooling fan, grab the fan as it will be easy to put in and it gives an extra safety margin when in traffic.

Don't we have any industrial refrigeration experts out there? Come on, Guys, The food industry has been using anhydrous ammonia as a refrigerant since the turn of the century. Hasn't anybody even heard of anybody that has a friend that has thought of trying this.It's cheap, it,s clean, stinks a little but hey!, IT WORKS. Anybody willing to go out on the proverbial limb on this one?
