The MB Folks sourced the fan and Fan clutch to one supplier in Eourpe. MB was able to gain more control by having both the Clutch an Fan as an assembly with some unique design and performance standards.
Abandon the bimetal valve control technology like that used in our GMC Clutches and employ an ELECTRONIC VISCOUS CLUTCH. Superior and more reliable.
As an assembly the fan must decouple after two minutes at 2500 input RPM. What a great feature.
