Oh and if you're planning on using R-12 with this condenser, make sure the evap temp switch is installed and functional. If not, the evap core WILL freeze and restrict air flow.

 

Jack,

I thought that part of going R134a was putting new fittings over the R12 fittings that once put on couldnt come off. Am I hallucinating again?

Thanks
Jim

 

my 134a conversion fittings can unscrew at will, so long as you evactuate the system

 

Hmmm... I could have sworn I saw somewhere that they had to be permanent by EPA edict

 

the manifold gauge set Jack pointed to was for R134a systems. Wouldn't you need some kind of adapters to use a R134a manifold gauge set on an RX7?

 

I bought a set of R12 to R134a service valve conversion pieces at NAPA here in Houston. They screwed right on with some minor mods on the schreader valves. The ones I got are definitely removable. The gauge set I have is for R134a only.

 

Cool. Thx, Red. I'd searched Advanced and O'reilly's websites but didnt find anything. I never think of Napa. Not sure where one is so I'll have to look!

Thx again. And can you guys take some of this humidity back?

 

Don't search the websites-waste of time.

Walk right into Orielly's and you will find an endcap with 'conversion kits' on it. That kit will have the fittings. It will also have a can or two of 134a and some ester oil charge, a BS charge gauge and a can tap. This is the infamous 'Death Kit'.

Right beside it there will probably be the service port fittings and oil a-la-carte as well. If you cannot find these, ask someone who looks over 40 years old. They may have them in the back. Don't ask a kid who will try to help you by asking the year, model and make of your car.

You need the fittings and some oil-DO NOT GET PAG! Use only ester.

Good Luck!

 

Cool. Thanks a bunch, Jack
