On my Edge Attitude monitor I can measure engine temps at startup. On a cold day when I fire it up the monitor says the temp is at 100degC, but not plugged in, its close to the outside temp.Calgary Cummins said:Seems strange to me ,how do I know if it is working ?

If you don't have that option, the "wait to start" light will be on less time, and you will notice that your truck will get to 140degC on the dash sooner, which seems to be the magic number as to when the heater will blow noticably hot air.
