Hi guys, Just keeping the trend going on this forum for the spring/summer season.
89 300e, I replaced the compressor, condenser, and have a receiver/dryer (new) on hand.
I want to "blow out the old lines to remove any old oil. From what I gather, I would disconnect the lines and pump compressed air along with some mineral oil until it comes out clean? Removing the lines is not an option at this point.
I will replace various O rings under the hood while im there.
My next step would be to add oil. Does anybody know how much specifically?
I read somewhere about depositing small amounts throughout the system. Is that true? If so, whats the procedure?
I want to fill my system with nitrogen once or twice to remove any moisture that remains, then charge with r12. I believe the spec is 2.2 lbs. can someone confirm?
Lastly, what kind of pressures should I be seeing on my gauges?
I have spent a small fortune on this a/c so far, furthermore, I havent had air in a car for years now... Id really like to do it right this time
