I’m having an issue in hot weather with my UltraGuage is indicating 212-214 and sounding an alarm before the cooling fan kicks on to drop the temperature. I’m not sure if this is normal or the specific gravity of my coolant isn’t right. I’ve already burped the air out of the system so I’m confident there are no trapped bubbles. I’ve also checked Xentry to see if there is a software setting to lower the temperature that the fan turns on, it it appears to be just a single temperature thermostat that turns the radiator fan on and off. Any thoughts?

Thanks in Advance!

Your car is normal. Both of my 451s go to 213 degrees before the fans kick on and the temperature goes down.

Fun fact: Many car manufacturers program temperature gauges to lie so the customer doesn't run to the dealership concerned about overheating.

For example, GM, VW and Toyota vehicles will indicate smack dab in the middle of the gauge when the coolant is between about 180 and 230 degrees. The needle only exceeds the middle mark when temperature rises above 230. So for 50 degrees of temperature range the needle does exactly nothing. Of course, 451s go even further by not having a gauge at all. lol


Wow! I didn’t know that!

Thanks to all for the confirmation my Smart is safe!
