Thanks for sharing this information.
I have struggled with this same problem as long as I've owned my S124.
Can you post some more pictures and/or go into greater detail on this process?
Very interested.

It's high 80's here right now and my normal drive which used to show way higher temps in the winter don't budge and it's summer.
Also I ran no fan for the first week and its in the 80's here in SoCal. So the fan and clutch make no difference especially at speed.
