Is there a metal thermostat or other metal housing that the coolant goes through as it leaves the engine? If so, I'd recommend a quick check of the gauge with a tire pyrometer or infrared pyrometer on said housing. I found that it was within a few degrees of reality, and it might indicate that your gauge is off if the pyrometer is reading lower..... :dunno:
If it is actually 250, something is wrong, I don't think any manufacturer uses a tstat that high.
