I'm mounting a new Sanden compressor in a 71 Comet. I have it mounted so the lines will be on the side, pointed at the drivers side fender apron. When I remove the factory cap on the compressor, oil will come out. I can rotate the compressor so the lies are point up then install them and swing it back so they are horizontal. My question is what happens to the oil? Does it get circulated through the system or is it supposed to stay in the compressor? Also with the horizontal line set up, what happens to the oil when the system gets vacuumed out? Any info you can provide will be appreciated.

Actualy may be better. Typicly one needs to manualy pump the oil out of the compressor so that it doesn't try to pump it when you turn it on electricly. Doing that can cause compressor to fail. I always try to turn the compressor at least 20 times before turning it on.
Most of the oil stays in the compressor, some stays in the evaporator and some stays in the condensor. But a little of it does circulate with the refrigerant. A little may come out of the service port when you take the cap off but it shouldn't be much. Not much you can do to stop that. A small amount deposits itself there all the time if the ports are horizontal. Running the compressor with the fittings on the side should not be problem with most compressors. Especially Sandens as they are used that way on many fords. RS
How much oil is in there. About an ounce came out. How much oil is in there. About an ounce came out when I unscrewed the bottom fitting. I wasn't expecting that. By the time I got the cap back on my whole hand was covered and oil dripping all over my new paint... What kind of oil is it exactly? I would like to replace it and make sure it has every smidgen it needs. How much does it hold? Can I drain it easily and measure how much is left? Thanks in advance. Danford1
Glad to hear you can run it that way. Those fittings get awfully close to my monte carlo bar and I was worried I might run into problems when I finally hook the A/C up.
Thank you Thank you for the Sanden link. That is just what I wanted but that brings up another question... Can I simply tip the compressor and drain all the oil out ? (so I can measure how much I actually lost). Or, will oil still be trapped somewhere inside of it? Thanks. Danford1
Typically when I recharge a system, I use the freon w/ the oil already in it. You could drain it if you want, might be better... but I never have. (not saying its the right or wrong thing to do) But I've never had any problems either
Here's the kind w/ the gauge already built in it. But, they sell it in the regular cans as well. http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_R-134a-EZ-Chill-Refrigerant-plus-Oil-(18-oz-)-Interdynamics_7010015-P_N3571B_T%7CGRP2004A____
We don't have that in Canada, it's probably flammable, and not good for the environment. Your last link, says it's not a replacement for the compressors oil, just an additive...
I've never used that last one before... but thought it was neat. I'm surprised you haven't seen it before. I seen it at any place that sales freon for automotives. How would the oil being in the can make it any more flammable than adding the oil and freon seperately to your car? I can't find what I've used online, but I've seen it in stores. It's most likely cheaper to buy the freon and oil seperate, especially if you do it for a living like you do. It's just convenient for us do it yourself type guys. I've had good luck w/ the stuff already oiled. I've recharged about a dozen cars or so in the last couple years and not one has given me any problems
