Kohler Genset Fan Question

[Scott Forman]

Has anyone ever installed a thermostatic control for the Kohler genset
radiator fan? I would see two benefits to doing this:

1) The obvious reduction in noise when fan isn't spinning

2) My gen seems to run at only about 160 degrees except on the hottest
days, meaning that the engine never really "heats up" all the way and,
therefore, never quits smoking. This, of course, leads to more exhaust
odor than is necessary.

Any tips?

Thanks
