Write-up on fan clutch repair

[The Warden]

Hello!

I know that there are a few people who've put new fluid in the clutch for the engine-driven fan on OM617-powered cars. However, I'm at a point where I'm confused. I need to do this job, and have seen people talking about different methods of going about putting the fluid in. Someone once said that you should take out the bimetallic spring and the metering needle and put new fluid (the Toyota stuff) in the needle's hole via syringe until it was full; however, others have said that you shouldn't do it this way and should instead open the unit up and add it in with the unit apart. I think that other methods have been outlined.

With the weather warming up, I really want to get my fan cluthc working as it should. So, my question is this. Does anyone by chance have a write-up on the job? If not, what's the "right" way? If the unit needs to be taken apart, how does one go about doing so?

Any thoughts would be appreciated...thanks in advance!
