Re: IML: A/C ReVamp

[randalpark@xxxxxxx]

I'm no expert but that's about all there is to it. The system works 
fine with 134A. I think it leaks out a little easier, but it is also 
simple and safer on the do it yourself recharge than messing around 
with R12. I have found that the old expansion valve usually fails after 
servicing, so if you can get a new one, that would be a good thing to 
change. The system needs to be evacuated again after having been opened 
to change the valve before the recharge.

The RV-2 compressor was the only compressor used on the big block 
engines, as far as I've seen.To install a newer style compressor, would 
require custom fabrication of all the brackets. I believe a rebuild kit 
for an RV-2 is $45-75, an exchange is $100-150.The 134 kits are less 
than $100 You will need a vacuum pump to evacuate the system, before 
the re-charge.Rebuilding the RV-2 isn't too bad, I've done a few, the 
FSM covers it good.Ya'll have a nice day, Dave.
