If you are using the compressor that came with the car (Sanden?), check their website and its service instructions. Put in what they recommend. If you are putting in a new compressor for R134, it already comes with the right quality and quantity of oil. Lacking knowledge of these things, I follow recommendations from the manufacturer. One thing you will probably want in Miami is a severe duty VOV. One place to get it is www.apak.com

Got the severe VOV, the compressor is good, just whant to replace the oil on the complete system, when replacing evaporator. I'll check today the Sanden model I have.

I think it is a VERY GOOD idea to replace the old oil with new oil. How was the old orifice valve, any metallic debris attached to it. How clean is the condenser internally? A flush of the system and even of the condenser individually may be called for, depending on whether there is debris attached to the orifice valve or inside the condenser. Once things are clean, put in the quantity and quality of new oil recommended by the manufacturer, likely about 8 ounces of PAG 100. Put in the new evaporator and a new receiver. Of course, use new O-rings all around. The Airsept inline filter would be nice. After the system is sealed, draw a vacuum, 30 inches of mercury for one hour will do nicely. Then, put in R134. I think your car takes about two pounds of R134. You may want to read flushing procedure at www.ackits.com to be used when compressor dies. You will probably need much less because your compressor did not fail and throw debris through the system. The ALLDATA CD for your car ($20) will help, unless of course you have the MUCH better Volvo shop manual. Knowledgeable Bricksters with Volvo shop manuals have no use for the ALLDATA CD, a VERY abridged version of the Volvo manuals. Best regards.

The compressor I have is ZEXEL DKS-15CH jap made, a label on the side kind of hard to see has OIL ZXL 100, I'll assume 100 viscosity, have not open the system, waiting for parts, is cooling good air tempdown to 40F, just have to add a can every 2 to 3 month.

Yes, that is a Diesel Kiki compressor. PAG 100 sounds right, readily available at places like Pep Boys and Western Auto. Zexel has a website in Japan with an English version. There is some interesting corporate information like Bosch is the major shareholder of Zexel-Valeo and car manufacturers that use their compressors, but I did not find much detail regarding service like at the Sanden site. One thing shown is that Zexel has operations in USA. Perhaps you could find them and contact if you wanted, but I think PAG 100 is right. You could still check with your A/C parts supplier since there are millions of Zexel (Diesel Kiki) compressors out there. Maybe I told you before, but if you do not have the Volvo manuals, an ALLDATA CD ($20 at places like KMart) for your car could help you with A/C service and other things because you get Volvo Technical Service Bulletins. If you are putting the evaporator in yourself or even if you are having it put in, be careful with the passenger air bag. Make sure all work is done only after the battery has been disconnected for a for minutes. TSB and the like will be useful. Best of luck.

I use this logic: the older the compressor, the higher viscosity I use. It's sort of like the older the engine, the thicker the oil. My 93 245 has 135Kmiles on the compressor, I use 150 PAG oil, no problema.
buena suerte,

Did you get the oil local autopart or net order.
