Re: shelf life opened DEC pag 100

DEC PAG is good to go. It does not suck up water like the old SEC stuff did.

Re: hybrid system 1980s/1990s questions

Some of those cars had A6 compressors, some had R4's. Since they were CCOT already, you just need to connect the new compressor. Use a new accumulator, they are 134a compatible. Use the OEM size White .072 orifice tube. The original condenser for that car was a tube & fin. You will probably ne d...

Re: Ford C350 Dual Air - trouble

Nice. A true parallel flow unit as a replacement. The best heat exchanger available for MVAC at this point in time. If you look closely at the headers you will see the dividers. The refrigerant makes passes from one side to the other through some of the tubes, and back across through others. Your re...

Re: Ford C350 Dual Air - trouble

Yeah, aftermarket installs can be a puzzle like that. I have a 1993 F150 with dealer installed A/C. Only the dryer is OEM... The good news is you got the dryer drilled & measured. The fact that it had that much oil when it locked up says it was not grinding itself to death, so the evaporators sh...

Re: Ford C350 Dual Air - trouble

Overall not a lot of oil in the system. There is flow at the rear TXV anytime the compressor is running. Usually there is some oil built up in the rear system if the rear blower has not been running. If you get the lines cleared out then you have a pretty much oil free system. Something to know when...

Re: Ford C350 Dual Air - trouble

Plan sounds ok to me. Obviously that plastic made it all the way from the compressor to the back of the vehicle - through the condenser. A great example of why we say flushing is a good idea. How much oil was present at the TXV? The insulation on the lines & the TXV is called Presstite. It is a ...

Looks like the replacement part for the Centurion is a Piccolo now

Re: Ford C350 Dual Air - trouble

The usual powdered aluminum "soot" and some elastomer bits. The dye is good news. A good blacklight should show any leaks. Replacing the condenser should get most of any debris. Since the Tee fitting for the liquid line is before the OT, check the TXV for similar bits. Many TXV's have a sc...

Re: Ford C350 Dual Air - trouble

Looks like the entire line set for the engine bay is under 50 bucks: http://www.ackits.com/ford-f-super-duty-v8-75-97-94-47210 That part of the line set sees all of the underhood heat & engine vibration. I would just replace a 25 year old hose set at that point. The condenser has been upgraded a...

Re: Ford C350 Dual Air - trouble

Well, that hose / service port would certainly appear to be the leak. Nothing around it has any evidence of spilled or flung oil. The question is, what was leaking. The service valve or the hose crimp. I believe that tube actually sits horizontal in the truck with the service port sticking up. If th...
