I've got a BE w 1,326 and Electric Fan set to turn on at 190 degrees. Thermostat set for 180 degrees opening. found that engine was varying at long stoplights, especially this time of year and fan cycling on/off. I did install one of those Canadian Radiators as well. Originally I still had the Mechanical Fan plus the Electric Fan et up as a Pusher. When I reinstalled engine after painting I used a different Rear Mount for my 210 tranny( I gained an inch of ground clearance BTW) which had the effect of bringing rear of tranny up and GR Started had more than 1/8" of clearance against the corner of the engine compartment. With different mount in place I could no longer keep the mechanical fan in place. I also installed a 160 degree thermostat, the need for heat in Tampa is slim and almost none even in January. I have yet to get engine wiring harness installed but this setup should handle just about anything without thermostat cycling and fan with Revotec Controller in lower hose cycling on and off. Whwn you turn off the engine, Electric Fan will kick on to cool down radiator temps down to at least below 180 degrees.
BTW Bob, where in FL did you move to. Hanging in Apollo Beach on the South Shore of Tampa.
