Hmm that's weird. Sounds like the settings for sure. I've read over the directions a few times. Maybe try this again?
8. Reconnect negative (-) battery cable to battery. Start the engine and allow it to idle.
Using a hand held thermometer (positioned near the inlet hose) or the vehicleÃÂs temperature gauge, monitor the temperature. When the coolant temp is slightly above
normal (or desired temp.), turn the knob counter-clockwise just until the fan turns on.
From now on, the fan should activate at this temperature setting. Adjust as necessary to
maintain desired temperature.
After the engine has been at normal operating temperature for ~45 minutes, adjust overflow tank coolant level to be at ~50% capacity.
