I have a 240 and I upgraded to an electric puller fan and removed the mechanical. The engine seems a bit smoother now with the change. I temporarily hooked up a switch to the fan while I sort out getting the thermostat installed. Issue is I need a good place to put the thermostat for the fan controller.

The unit has a 3/8" NPT thread and will fit where my temp sending unit is in the head, but I don't want to lose my temp gauge. I am not using my transmission cooler portion of the radiator, but the unit is too big to fit in there. Any ideas?
