Do you know what it has for a thermostat temperature wise? If it has a typical 193 degree thermostat, holding at 200 would be normal. Typically, the engine temp will stabilize around 10 degrees above the opening temp. BTW, the manufacturers of the clutch fans never recommend using any kind of spacer with a clutch. Honestly don't know why, but Hayden and 4-Seasons warn against it. They do make extended shaft clutches for some applications.
