Replacing compressor, condenser and Expansion Valve from Rock Auto parts. The compressor is a UAC brand and came filled with 6.1 oz. of PAG 100 oil, but it also came with a bottle of PAG 46 oil, so dont know the correct weight or amount, the under hood info just says PAG oil. Also cant find the Expansion Valve on my car. Any help would be greatly appreciated.

On our 2010 and our 2016, the expansion valve is UNDER the engine air filter box which is not too hard to remove.

Thanks, but found it the other day on the firewall behind the engine!!! After moving as many wires and hoses as I could I had about 4 in. of clearance to work with, then they use 2 Torx screws that would not come out,striped the heads and had to drill them out!!! I guess leaving them were they were made it to easy?
