Well now I'm not sure which pulley to use...
the Pulley on there turns about 1/2 turn when I spin it. (Fenner from the parts store) The one I took off that is from 2014 Turns like a quarter turn when I spin it. (INA from Pelican parts.) Both look pretty good. I guess I'll try it with the one I just cleaned and put back on and if it chirps I'll swap them out. |

INA is probably a more reputable brand. If it has a smooth feeling to it, I'd reuse it. It never squeaked with it installed right?

I'll put it on. I cleaned it and scuffed it. |

This is not on a Benz, but this worked for me on the AC belt of a Nissan Hardbody which are notoriously picky with V belts. All belts were new and tension was good. What you're going to read seems counter intuitive, but it if you're going to change the belt anyway, which is where I was, you've got nothing to lose.
I saw a video on the YouTubes where a guy said to spray the belt with 303. https://www.youtube.com/watch?v=_8RE8p_m8bA I couldn't find my bottle of 303, so I used Mother's VLR which is similar and smells the same with more cleaning ability. Squirted a good bit on all sides of the belt with the motor running and the AC off. When I turned on the AC it was improved considerably, but would squawk for about half second when the compressor kicked on. The following day, DEAD SILENT. This lasted for about a month until I noticed a little chirping at idle. Sprayed some more product on it and it quieted down again. |

OK. What's this fan clutch bearing?
I put it together and it didn't screech. I put the fan on it started to screech. I took the fan off and it still screeched. |

There is for an E320. Just not for a diesel. The pulley behind the fan is connected to the water pump. I tried the water test and it is the belt. Stops for a few seconds with water. Ugh.. New belt again. |

I've got a new water pump coming.

Fingers crossed that I don't need one.
Got the fan back on. Drove for half an hour and now we are back to a pleasant chirp. I'll live with the dang chirp. |

When water spray makes it quiet, that isn't a water pump issue.
The pulleys might need cleaned again. Did the label get lightly sanded? |

Chris, I read your Post#27 again and it's not normal for the water pump to make a scraping sound when you turn the pulley. How old is the water pump? It's possible the water pump is starting to fail and needs replacement. If so, best to buy a remanufactured one from your local MB dealer. Turn in the old one to avoid paying the core charge.

Water pumps will have a slightly dragging, rubbery feel due to seal friction.
