Title: 85 Suburban A/C questions.
Post by: TRAZOII on July 23, 2017, 01:38:06 am

Hi guys,
I've searched the topics and couldn't find the answers. So here I go.
1. Where is the orifice tube located?
Pic would be nice and which direction is it installed?
2. If some idiot (me) can't find the oem ac brackets that came on my 350 ci. Where can I find replacements? Or what else can I do? I'm running the GM R4 "pancake" compressor.
Thanks in advance everyone.

The orifice tube is at the bottom junction of the lower AC hose coming out of the AC box.  it has the AC fitting right in front of it..
You can see it here with a cap on it

Do you have rear AC?
