Should I replace Desiccant in VIR?

BG1 on Mon April 29, 2013 8:19 PM User is offline

Year: 76
Make: Pontiac
Model: Firebird
Engine Size: 455
Refrigerant Type: R134a

I had converted the system to R134a and it worked pretty good but I pulled the engine to rebuild and disconnected the compressor and its been a year and now I have time to reconnect the ac. I did plug all the lines and the connections on the VIR but I would figure that over that much time I would need to replace the Desiccant in the vir but figured I would get other opinions. Thanks

Replace the dessicant bag. Cheap insurance. Good idea to flush, drain, and replace the oil too.

I agree with AutoCool, why risk having to do the repair all over again for a inexpensive part. Let alone it is just the right thing to do!

Do I need to flush the system again? It had only been back together a few months. I had flushed it and added new oil.
Same thing with my 90 Chevy truck, I need to replace the compressor and had just flushed the system and got it working good and it sprung a small leak and let out the r134a. So do I flush the system again (I have not disconnected anything yet). Thanks

Is there a way to find old post? I am having trouble finding the old post about converting/adjusting the eevir by Mitch and Dougflas. You tried to post a link to this back Fri May 07 2004 11:21 PM,down below is what you said. I tried but the link does not work and I tried to find the article but did not have any luck. I know this is old information but I know of someone looking for information on this topic. Thanks BG

Jump over to the FAQ Forum as I put a few of Dougflas and Mitch's POA posts there for easy access.
