What PAG oil do I need? W/PICS

alexk243 · Post by **alexk243** » 16 May 2013, 17:56

So I am about to dive into an AC Evap replacement on my 1993 Volvo 850 and I am ordering all the parts I need so far I have gotten:

-Evap Core
-Drier
-4x O-Rings for Drier/Evap
-O-Rings for heater core/clips
-Odometer Gear
-AC Manifold Kit
-Vacuum Pump

Anything Else I need?

I know I need PAG oil, I just cant figure out what kind. Below are pictures of everything ACish I could locate. Any help as to what weight oil would be great.

Don't take this the wrong way. But if you are going to be working on the a/c at least know which component is the compressor.

Here's a hint - Bosch tends to make...electrical type components...

I would do some basic research on a/c and what components go where (evaporator, condenser, accumulator, etc.) and find them on the car before taking a crack at it.

Don't feel bad, I had to ask on forums when doing my first brake job about stuff, and was told "if you have to ask you can't do it" but I persevered.

The compressors on these cars are usually made by Zexel. When you do locate it, look on it for the model number and manufacturer. Then go to this link and look up the proper weight:

hahahaha wow, I deserved that. Honestly when I took the picture I was rushing and didnt even think twice what I was taking a picture of. In my mind I was looking for the alternator... and I found it. Not till just now when you pointed that out I realized that I was not even thinking. (I have replaced Alternators on Toyotas, Jeeps, and other cars and am pretty familiar with them lol)

Thanks for pointing that out. I may never have noticed lol. ok ok, Ill go open the hood again and find the AC compressor.

Ok, I looked again and the only identification I could find on the Compressor was the following:

Zexel 506491-2991 (12v)

Any idea what type of PAG oil I should buy for it? Planning on doing it this weekend so I need to order quick.

JDS60's pdf is probably right but I thought Lee has posted that he has seen some of his 850's needed different weight PAG oil. That would be counter to what the pdf says. Or maybe it is because not all have a Zexel compressor. At any rate, you are so close, you might as well be certain. On the green sticker where you got the number you posted, the Zexel model is just to the left. Like this:

: The compressor model is inside the hand-drawn blue box. This one is a DKS-15CH, so it uses PAG 46 oil.; AC compressor sticker.jpg (186.59 KiB) Viewed 2092 times

Also, there is no need to order the PAG oil from Volvo. Just get it from any auto parts store.
