The reason I ask is because your gauge may be messing with you. It may have always been showing the fan coming on at 200 when in reality its coming on at 210. Maybe now the gauge screwed up again and is showing a different temp. You'll know this once you hook insite up.

There are many things that kick the fan on. Coolant temp, oil temp, intake air temp, a/c pressures.

You can always add an aux manual switch to the fan. The prostar guys may be able to chime in on how to wire it. Some trucks if hooked in wrong will operate the fan but will also throw a check engine light for the fan circuit.

I have a Kevin Rutherford gauge and I just changed it to monitor my coolant temp I only have 15K on the deck and the temp has stayed at 182 I will monitor it today it has matched the gauge sofar....
