Does anyone have a copy of the W124 Bible?
 

If so, I need some information. In section 5, there's supposedly a procedure on adjusting the fan clutch to get it to lock up earlier. There are a few mentions of this procedure from ~2005 on other Mercedes forums but none actually outline it like the book does and none of the members are still active. Something about drilling a hole and adding a screw in the bimetallic strip. I could buy the book but it's rather expensive and I only need it for this one section.

Any help would be greatly appreciated. Posting this to multiple sections for visibility.

I’ve got it. P.m. me your cell number and I will send you some pics of the relevant pages.

Solved!

Had my friend do the mod on my parent's Sprinter van, he's got to adjust it some but says it seems to work well to get the fan to cut in much earlier and keep temps down and improve AC. I'll get back to you with long-term findings.
