Engine Temp what is normal????
Very interesting discussion. My 600SL runs at approximately 95-96 at steady cruise. But, the least amount of acceleration or a hill sends it 98C and the Viscous fan comes on 96-97. This fan is extremely loud and for top down driving it destroys the ambience. Any way to quiet it down but retain its efficent operation?. I wonder if the noise is the fan proper or the clutch.
