Can anyone look up the oil capacity for the compressor on a 01 lexus is300? I got a remanufactured compressor and the company fills it up with oil and tells the customer to drain and refill to oem specs. The only problem is the service manual only gives the oil needed (ND 8)for the condenser and not the compressor. I've looked at the pdf (http://www.autoacforum.com/speclisting.pdf) going around for car oil capacities, but it is blank for my car. My luck.
I show a capacity of 4.5oz for the compressor.
This specification should be for total system capacity. The vehicle uses a rotary vane compressor and adding this amount of lube to the compressor may result in possible internal compressor damage. Suggest to add no more than 1 to 2 oz to compressor.
The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government.
With so many different R-134a compatible oils on the market today, mixing oils is no longer myth, stick with one oil.
Didn't your wife or girl like the color of your old compressor for the reason for changing it, or did the old one fail. If the latter, should completely flush out the system, replace the receiver, draw a deep vacuum and recharge using the recommended oil.
In the service manual it says if the condenser is replaced add 1.4 oz of nd8 oil to it. If the evaporator is replaced at 1.4 oz to it. Thats all the info that it gives. If Adams spec is true that would leave 1.7 oz for the compressor. Not to doubt Adam at all, but can I have a second confirmation of the 4.5 total capacity. Just want to make sure.
Once again, thanks for everyone's help.
I have gone crazy with my Honda manuals, Toyota Supra manual clearly states 5.6 ounces. Refrigeration capacity is 24 ounces plus or minus 3 ounces, precise charge is determined by P-T charts. This gives a mean ratio of 4.2 to 1 for the ratio of refrigerant to oil that appears to be well within the ballpark when compared to larger systems.
No knowing the refrigerant capacity of your Lexus, that 5 ounce figure should be pretty close. Tim has a good oil that is no so much moisture prone, can't recall the name of it off the top of my head this morning. Sure he will state it.
Iceman is pretty good with this stuff so I would stick with his recommendation.
My point is I have seen repair programs list a certain amount as the system capacity and I know it is incorrect for a certain type of compressor. This is done mostly with the import data in Mitchell and Alldata.
My point was, why is the compressor being replaced? Sure don't want to replace a compressor in a system loaded with debris, they don't last very long.
The compressor wasn't building any pressure until higher rpms and it was making a lot of noise. I purchased a new condenser / dryer as from what I've read its holds most of the crud if something goes wrong and flushing it doesnt always get everything out. I will have to pull the dash out to get to the evaporator core to flush it out as the expansion valve is connected about 6 inches away and from what I've read I cant flush the expansion valve. I may just replace them as whats another $150 when I've already gone this far.
Again, thanks for everyones help.
