ac pump with yellow fluid in it

[AlaskaDan]

While swaping parts from the 3.5 to the 3.7 I was cleaning up the ac pump. When I turned it over a yellow fluid came out. Consistancy of transmission fluid, but a dark piss yellow (sorry but describes the color perfectly) and no smell. Is this freon turned to liquid ? Should I dump it all out or is this some kind of lubricant that is suppose to be in there?

That oil needs to be in there. It's yellow because the system had leak and they put the die in it to help find the leak.

You need to replace the same amount of oil that spilled out. PAG46 I think is what it takes. Any auto parts store will have it.

Thanks. Will do. Glad i asked.

Just a FYI,you also need to pressure test the system with nitrogen,to make sure there are no leaks. The next step is pulling a vacuum to 500 microns. Then comes the 134a freon charge.
