I have to mention that you seized 2 different compressors, from 2 different manufacturers, on that one job. One compressor was an OEM part. Ester oil is not recommended by OEM manufacturers. Through several years of testing , manufacturers have found PAG oil to be the recommended lubricants. You cannot mix PAG oil along with ester oil. They will NOT mix. When you have a compressor failure, you do have to replace certain components, you have to flush the other parts and to fully vacuum the entire system. These are steps you did NOT do. You did not follow proper procedures. You just cannot remove and install a compressor without doing any of the above. Here's what I copy / pasted from a manufacturer's web sites: If the wrong type of compressor oil or the wrong viscosity compressor oil is used, it may damage the compressor. In fact, the main reason for a newly installed A/C compressor to fail is using the wrong type of compressor oil."Universal" A/C compressor oils are often PAO-based and are not the same viscosity as the PAG oil recommended for a specific type of compressor. This can lead to poor lubrication and premature compressor failure. If you follow the Mitchell Guide, as an example, the lubricants recommended for the job you were doing, was PAG 100 . I had 3 different manufacturers™ compressors in stock at the time you did the installation. All 3 stated PAG 100 ONLY It should also be noted that on another a/c job you were attempting , you did purchase PAG oil from us through a local distributor, so we would not know who you were.I guess I did get through to you. 1-800 Radiator does warranty its parts; but when it gets to NEGLECT and or ABUSE , you sometimes have to draw the line. A/C jobs are best left to the Pros. Norm 1-800-Radiator of Ottawa
