Noise in the electric fan when the AC is running on MB 210.025

Hello everyone,

I have a Mercedes Benz 210.025 and when the air conditioning is on I am hearing an annoying squeaking noise from the secondary fan, I think. I believe the electric fan is fine.

I took the fans out to check and I can't disassemble the fan that is making noise, since my intention is to lubricate or change the bearing if it has one.

Could someone tell me how to disassemble these two fans to proceed to check and repair the bushings or bearings? If there are photographs or videos I would also be very grateful.


Thank you very much.

The electric fan only works when the air conditioning is on.

These fans are original and I want to keep them that way. For this reason I want to service them so they can work again without noise.

Thank you very much for your reply.
