My 99 lx 470 had an ac compressor failure because the ac system was in bad shape. I’m going to be flushing the lines and replacing basically everything. The compressor, front and rear evaporator, front and rear expansion valves, condenser and the ac lines that have the mufflers on them. I’ll also be using Nylog on all the connections and o rings.

Since I’m basically starting with a clean system with nothing in it. How much PAG oil do I need to put in it? Ive tried looking but I keep seeing mixed answers on the exact amount for each part.

Also to add the PAG oil, I just pour it straight into the evaporator/condenser/compressor before installing it back? Or is there a special way of adding it.
