I have a 2003 Honda Accord 3.0 V6 that needs a new AC compressor. I bought a new one and need to know how much oil to add to it. The instructions on the new compressor say to measure the oil from the old compressor and put the same amount of new oil in the new compressor but the old compressor blew most of the oil through the seals before it finally quit. How much oil do I need to add.

Thanks for your help

I don't like how the honda shop manual describes the a/c oil capacity. Doing the math, the a/c system should take about 9oz of oil.

If the compressor broke down internally, then you probably should clean out any metal that likely got distributed through the system.

With a/c repair, if you repair it thoroughly the first time, it will last for a very long time.

Here is what I would do. Take out all the components, flush them out with some kind of solvent (something like denatured alcohol or acetone). Allow them to dry. Replace all the o-rings, the receiver/drier, and the expansion valve.

Put it all together and add the proper amount of oil to the components. The shop manual says to add 25mL to the condenser, 10mL to each hose/line, 45 mL to the evaporator, 10 mL to the receiver, then 160-175 mL to the compressor.

Then pull a vacuum on the system and see if it can hold a vacuum.

Then charge the system using the proper amount of R-134A (17.6-19.4 oz).

 

Thanks for the reply it is very hellpful.
