Back at it. I do not want to hook up (open up) the drier until it is time to test and fill the system. The sticker under the hood calls for 7oz oil and 2lb 1oz refrigerant. I am assuming this is for the stock system, not with the rear AC. I saw on this forum to add 1 to 2oz oil for a GM/Suburban tha...

New part should be here Friday.

Now for the big question, how much oil do I put in? Any extra for the rear system?

What about a charge?

Ideas?

With regard the hose... I sent some time on the phone/email with UAC yesterday. I think they may have part numbers reversed or there may be more than one part number for my application. The UAC online catalog indicates a HA 10407C for a 1994 F350 Vin K engine (7.3IDI Factory Turbo). That is the new ...

Lets see... The old one I took out looks to be a hybrid of sorts (maybe). It has two headers on one side. The flow comes in one header, across and back the small tubes, and then out the other header. Here is a pic of the other side of the old condenser. WP_20190311_12_27_53_Pro.jpg The new condenser...

Well, working on getting this together. Pulled the compressor and there is no oil draining from it, at all.... I pulled the drier, drilled a hole in it and it drained about 2.75 oz. The replacement hose, a UAC HA 10407C was about a foot short between the drier and the compressor and does not fit. Th...

I guess that will be the next big question... how much oil and how much refrigerant.

I guess the oil will be somewhat dependent on what comes out of the system. I'll see what I collect upon disassembly. Not sure about the refrigerant...

I figured there would be something back there as there was plastic in the orifice tube as well. While it was apart I was going to blast the rear supply line (?) both ways with shop air to try and remove anything that is still in the line. It had a little (emphasis on little) oil back there, but not ...

I think the Centurion may have a piccolo in it now. WP_20190303_14_33_05_Pro.jpg I looked into the TXV and saw one elastomer bit. That was it. Otherwise very clean. I did not remove it as it was encased with some sort of goop assumed to control condensation. It looked like it would be a PITA to get ...

The plan is to check the valve today. I'll fill in the details after.

Was there a condenser upgrade for the Centurion?

So I have the orifice tube out. It was pretty stuck in there (so glad I had hemostats). I do not think it looks bad. The oil had dye in it, quite bright. There was not much, but some almost graphite colored soot in some of the oil in the nooks and crannies. Not reflective like metal, but just grey. ...
