I'm at the R12/134A crossroads...

[commando1]

...with my '76 with the original RV2 compressor with R12.
Previously, I always went the proper routewith getting new compressors rebuilt for 134A.
Recently, the A/C has just started blowing warm but funds are really bad at the moment.
So what's the truth? What's the bottom line?
Who has used the Wally World so called "conversion kits" (really R134A with adaptor fittings)??
Do they work? Don't forget I'm in Florida.

R134 will never get as cold as R12. Rumour has the feds are looking to phase out r134 too, or at least make it very expensive.

Low pressure side adapter is in all of the universal kits. I could charge the system ok with it. I couldn't find a high side adapter that would work, so I couldn't check high pressure readings.

I read it.
I reread it.
And I re-reread it.
Everyone that commented was a Rocket Scientis theorist and not ONE of them came up with a viable plan that works. NONE. All were flapping their pie holes to look important.

Basically, the bottom line is the tree-huggers want us all to die by sweating to death.

This is the kit I used. It worked very well.

Mike, did that kit have the right adapter for the high pressure side. Where is it available? Quest? I charged the system last fall just to make sure the compressor worked. I've got a new H-Block, receiver drier, and a flush kit. I'm going to get the hoses redone at a local hydraulic shop and charge her up again. Also going to start stock piling R134A freon before the price really gets out of hand.

I think I read somewhere that you have to remove the EPR valve from the compressor and replace it with a thermostat. I'm not sure if this is correct.

It sounds like you have a leak somewhere in the system. I would find it first before recharging the system.

That doesn't have to be done but it SHOULD be done for best results.

Tsk, Tsk, Tsk Commado you ought not dismiss saving the world from the evils of mankind so lightly. What about the polar bears?:mek3:

Polar bears? You go hug one first and then I may think about it.

Huh? But the TV commercials say they are cute and cuddly furry teddy bears

Stan, have you decided on which direction you are going to go with the A/C?

Hmm... thought I already told the outcome long ago. Maybe it was The Drydock.

Anways...
Flushed system and checked for leaks. Luckily none found.
Changed o-rings and fittings, removed EPR valve, filled with that fake stuff and it's appropriate oil. Reads 45 degrees at the vent outlet. I'm happy with it.
I have the thermostat ready to install in case the condenser shows signs of freezing.
