I plan on flushing my ac system and then there will be no oil in it, so what is the best way to add oil, all in the compressor or do I have to add the certain amount into every component? It has a Nippondenso 10 cylinder compressor. I know that the system holds a total of 5.82 oz. I'm going to replace all the o-rings because that's where my leak is. My local ac shop told me to use a can of A/C SYSTEM AEROSOL POWER CLEAN & FLUSH How do you actually is it? Open a line some where or completely bypass the compressor and drain that separate?

Thanks for your help.

Before attempting to flush (especially if you have not done it before, and an aerosol can has been recommended), read the document in my signature below.

What HECAT is getting at is that flushing improperly is worse than not flushing at all.

If the compressor has an oil sump, put all the oil in there. If not, put as much in the compressor as will fit (by pouring it into the inlet and rotating the compressor by hand off of the car) and the rest in the receiver-drier (use a NEW receiver drier of course). It's important to get a substantial charge of refrigerant in before starting the compressor for the first time so that the oil can circulate. Running on a low charge tends to move all the oil out of the compressor without enough refrigerant to push it around and back in.

ok I see that now. I was planning on having my auto teacher help me at school, he has done ac at the ford garage before. I know that I have to make sure to get all of the solvent out afterwards. What is the best way to use the aerosol ac flush im going to use? Will I have to remove all the lines?
