hey guys i got the 383 in, but of course i had to purge the a/c system in my 92 firebird... It worked fine before the motor swap...

What do i need to do to have it recharged? The line was disconnected from the compressor for under 24 hours, do i still need to have a vacuum put on it? I'm guessing 92's still used FREON which is real expensive?

Thanks,
Shane

 

someone answer me damnit.

 

Why did you purge the system in the first place? The hoses should be flexible. I just unbolted my compressor and wire tied it to the fender.

 

Here are a couple of quotes from my Chilton's on the subject.

"Cap the refrigerant lines when opening the system to prevent the entry of dirt and moisture and the loss of refrigerant lubricant"

So I would say if you didn't cap the lines then I would have it vacuumed out just to be safe.

" R-134a refrigerant systems are not compatible with R-12 refrigerant or components. The use of R-12 refrigerant or components in a R-134a system ( and vice versa ) will cause leaks, poor air conditioning performance and compressor failure"

Now this last quote is all through the air section. I had my air system changed over to 134a and all the guy did was add the correct nozzels to fit the 134a fittings and vacuum the system and this guy was a GM trained mechanic.

I would say take it to your local shop and talk with the mechanics about what your options are. If you want to go your own way I think there is an article about chaging over to 134a your self in the tech section on this site.

I hope this helps out even a little.

 

I would and did retro it to R134, and I would get it flushed out good.


Peace

 

how well does the r134 work?
