I've got an 04 f250 6.0. I have replaced the whole AC system except for hoses. checked the hoses they look fine. My question is how much PAG oil do I need to put back in? I'm not sure the compressor has oil in it. I'm going to check tomorrow before I put it back in. From what I can find on the world wide web it takes 9 ounces. Also can I dump all 9 ounces into the compressor or do I need to add certain amounts to each part? like dryer, condenser, evaporator?

Thanxs

 

I think the compressor comes with nearly 6oz already. Check with the seller, they can give you the exact number... that so it doesn't start dry. The PAG oil comes in a small can, something like 3.2oz and I want to say its PAG42 or PAG46.

 

yeah I got it off of parts geek, its motorcraft but when i called them they said it didn't have oil in it. I was going to turn it over and see if anything came out then just measure and put it back in. And i already have a bottle of pag 46 8oz. I just wanted to make sure I was putting the right amount in.

 

9oz is the number. I just recently did the same thing, but my compressor had some oil in it already.

 

Cool thanks. can I put that all in the compressor or should I put some in each part?

 

Dump it into the compressor, you can add it through the low port if needed later... it all eventually makes its way to the compressor.

 

Lol, thanks I had a feeling that's what I needed to do. Had to make sure.

 

If you can give me a little bit I have a PDF from the workbook that has the
amounts for each part if replaced that needs to be added.


The first PDF is from the 03 and the rest are from the 04 folders on
my computer. I think they are both the same.

Hope this helps.

Thanxs, I'm saving those to my truck file.

 

The only way you will know exactly what's in your compressor is to pour it out of both the suction and discharge ports and measure it (hopefully without your wife finding out you used her measuring cup). So if you know the rest is dry, I'd shoot for 10OZ. Only two things can happen from having too much oil; one is is you have waaaay too much oil you can hydraulic the compressor and kilt it, but you probably already knew that. The other problem is, oil takes up space in the sealed system. Space that should be there for refrigerant, so your system may not blow quite as cold as it could, but an OZ won't cause that. After you get all finished up, check the temperature of your discharge line. You do not want that to be over 200 degrees. Then check the temp of your suction line (the bigger one). You don't want that to be under 34 degrees or you could have some freeze up trouble. Oh, BTW, if the old compressor had a relief valve, make sure to transfer it over to the new one, I'm not sure where Ford puts the HPCO these days.

 

did you share the pdf you mentioned

 

It must of gotten removed from my list of files.
Here is the 2005 year version. I will hve to find the 2003 s there may be some changes.

 

Yeah, that darn under hood label is no longer available from Ford. I took a pic of mine for future reference when I replaced that rubber piece this last summer. B.
