Mercedes W126 560SEL 89 Tutorial: AC compressor oil & O-Rings, checking a leaky AC system correctly
Рет қаралды 583
4 ай бұрынNote: I am posting this video for a second time as the first post had the segment about the correct MB Manual Technical Note missing, which I think is a important piece of information!
Getting my AC ready for the spring and summer. Most O-Rings are shot, so I started with the compressor and its manifold.
Selecting the correct PAG 46 oil for R-134a is important so is finding the correct manuals

Most of the leaking comes from the seal in the compressor impeller clutch pulley😡😡

Yes, correct. But you can pressure / vacuum test the compressor after replacing the o-rings to check for shaft leaks. In this case it is ok. No shaft leak, I should have mentioned this in the video! Thanks for your comment

When you refilled system with freon where is the low side ? By radiator or above driver wheel well.

The low (blue) side is the big hose next to the fuel cooler
