Help, need to replace the compressor

go100map on Tue August 11, 2009 9:42 PM User is offline

Year: 1998
Make: honda
Model: civic

I am trying to replace every thing except Evaporator, pipes in the AC system with my honda CIVIC 98 car.
Do I need to drain the oil out from the OEM sanden compressor? If so, how much to drain.
Can I drain all the oil out of the compressor and add a measured volume in ? I am totally confused, thanks in advance for your suggestions.

Why are you changing all these parts?

because of compressor failure , drier ,expansion valve, compressor are must, I choose to replace the condensor and flush the evaporator , that's my plan.
what confusing me is do I need to drain all the oil with the OEM compressor and add measured volume in ? I don't know how much oil is with the new compressor

Depends on what the compressor supplier states. Myself unless it a new compressor I drain the oil and add back the OEM specification. That said I also do a complete system flush and replace the drier. Hecat has a good article on flushing in the flushing forum.

I don't know why they even bother adding oil to the compressor, I want to know what kind of oil I am using and to put in the precise amount. Too little and you risk failure too much, and you reduce cooling. Could never find the precise amount of oil in my older Hondas, they never specified it in the shop manual. Best guess is about 5 1/2 ounces, prefer to inject it after drawing a deep vacuum so not adding moisture to R-134a systems, and with Honda, use their fluids. More of a different kind of car company than a Saturn. By the way, what happened to Saturn, was here one day and gone the next. Wife and I looked at new Honda's, sure are making some crazy looking cars lately, somebody else can buy them.

I agree, I'd rather add my own; maybe they figure some installers will forget. I purchased an Airpro rebuilt from the board sponser for my '88 Mazda B2200 truck about 2003, and it had oil in it, but not the mineral oil I wanted, as mine was R-12; I determined oil type by FTIR analysis at work. So I drained the oil, added maybe 6 oz. of mineral oil, turned by hand a bunch, drained again, repeated, etc., then filled with correct amount of mineral oil and installed it.

A co-worker the next year bought same brand of compressor for his R-12 1990 Mazda Protoge, and we tested that oil, and that one did contain mineral oil as received. So I'd rather just add my own oil.

Never knew what was so difficult about lubricating a compressor...does it have lube....or is it shipped dry.....how much is in the compressor.....there is a most simple method to determine exactly how much, if any is in the compressor....simply drain and DISCARD!!! Get rid of the old stuff...it is not gold.....does not have any residual value.
Refill the compressor with the correct type, amount and QUALITY lube for the system. Normal recharge rate is app 25-30% of standard system lube spec.
I would never trust anyone I did not know to determine the final outcome of my AC repair....and by not addressing the amount of lube in a compressor is the first step in that repair. One would find it most difficult to believe the number of tech calls received each day...many from 'techs' wanting to know if a compressor was dry or had lube...and if it had lube...how much was in the unit!!! Boggles the mind !!! Many take offense when told to simply drain, dispose and refill......it is as if this included lube has some magic characteristic or intrinsic valve.
Even those units that are shipped with lube.....ne never knows how much is in the system...a couple oz....a complete recharge...or perhaps...someone forgot to charge ....and then.....opps...another warranty unit.
Last summer a large supplier, OE units....owned by a major auto mfg'er.....one that did not take the money from the gov.....was shipping compressors with a label that stated the compressors were pre-charged with lube....yet....when the seals were removed and the compressor drained.....my..my....my...not one oz of lube was present. Wonder how many of those units were in the market place....and how many were destroyed at start up?

I just did a compressor replacement and the first thing I was concerned about was "Is there oil in the compressor?". I verified that there was, but in addition, there was a Tag Wired to the compressor that stated the amount of oil in the compressor as well as the type. It was the correct type as called for for my vehicle...
