Good tip, thanks!

Standard procedure is to rotate a new compressor by hand at least 10 times. That's after adding oil of it was shipped dry. To be clear, hand rotate prefilled compressors also. That's an industry standard excepting rare designs.

Jim did , saved 1.23M in costs , he lives on a private island now .

Yep push the cost down stream

Ya I’ve been a mechanic for ten years. Done many compressors hardly ever paid attention to oil levels or do any kind of flush. We have literally never had a single come back or complain or issue. Every ac system I’ve done was perfect. Sounds like this car had other issues

I remember long ago working at a parts house, a friend of the store had four, yes four "defective" ac compressors exchanged and we never found out the REAL story why. It remains a mystery till this day! LOL!!!

​@@Adabulldoyanot all compressors will come with oil in them.

@@henrymorgan3982 If the first compressor failed and broke internally, it could have thrown debris inside the whole A/C system. They pieces would then make their way back to the new compressor and break it. The whole system, condenser, drier, evaporator, lines and hoses needs to be flushed before installing a new compressor. The Car Wizard has a story just like this on his channel.

Oh it's possible. But it's illegal - venting refrigerant intentionally is a federal crime. Not to mention expensive and wasteful. (I think they meant just flushing it with some kind of liquid flushing chemical.)

You flush it by using the a/c recovery machine. It has the ability to use the refrigerant from the stored internal tank, to flush the system.

@@allanb3222 So you're saying that you charge it and recover. Again. What?

@@madmanmapper No bro, it uses the flushing feature built into the the recovery machine.

@@allanb3222 you can use solvents and an AC flush machine (purpose built for flushing task). AFAIK there are no flushing machines which use refrigerant- they all use solvents. Mind you, I'm not a "pro" but I've been working on AC systems of my own since the early 1980s- never heard of flushing with refrigerant. Refrigerant in a system is designed to flow the opposite direction of flushing fluids, IOW you flush in the reverse direction of refrigerant flow. Of course if you have had a catastrophic internal failure of the compressor with most modern systems (>2010 to present), you cannot flush condensor units and must replace instead. Mind you, I am speaking of R-134a units- I have no experience with the newest refrigerant variants yet.m If you know of a recovery machine which flushes with refrigerant, I would be interested to know the make and model as I'm always learning - and I do get dirty doing repairs as well. Cheers.

Just reinstalled my 95 taco ac system. Was ripped out by previous owner. I saw the compressor was pre filled and just sent it 😂 ac works now so that's good enough for me

@@gopro2027 It seems that's a theme with people who have older Toyota trucks. Rip out or "delete" whatever they can't fix or understand. Or, were they planning a 1,000 hp LS swap?

37,5% is about 35%, 12,5% could be about 15% if you squint a little. Seen worse approximations.

You drain about 30 cc from the old compressor which equals about 35% of the total amout of the COMPRESSOR ? No 35% of the total SYSTEM.

🤦🏾‍♂️I thought I was the only one here that was scratching my head on this..

Im hoping i made a good detailed educated guess. One of my cars started leaking refrigerant slightly after getting it operational. At least it was parked in the shop and i could see the oil stain and small puddle. Glad i found out the new compressor is filled with enough oil for the whole system, so i emptied what the new one had. Then i added what it called for in the compressor. Went over to the oil spot,poured some out to match the stain and noted that amount ,and added that in. I was surprised that it was almost 1/2oz worth. Been 3yrs and no funny noises yet!

Dear Saeed, Yes, we have 100% vapor at the suction side of the compressor, to prevent the compressor from sucking liquid refrigerant, which can cause liquid lock. We call this superheated gaseous refrigerant. The temperature of this superheated gaseous refrigerant has to have a temperature between 5- to 10 degrees Celsius. If the superheat value is too high, then the oil return comes into danger. This can happen when the refrigerant levels becomes too low. We call this difference in superheat, wet or dry vapor. Wet vapor is carrying oil. Dry vapor not. Therefore it is also very important to use the right type of compressor oil, because only a good quality compressor oil has the right miscibility properties in every state of the refrigerant. (Liquid or gaseous) Denso oil types ND-oil 8: Denso specific PAG, with viscosity 46, for R134a refrigerant. (Not useable for R1234yf refrigerant!) ND-oi 12: Denso specific special PAG, with viscosity 46, for R1234yf refrigerant, but can also be used for R134a refrigerant. ND-oil 11: Denso specific POE oil, especially for Denso electric driven scroll compressors.
