It could be your gauge, but it's probably easier to start with the t-stat. How close are you to one of these places? http://www.cummins.com/na/pages/en/d...r.cfm?state=OH

razor,

I had the same symptoms - could not get above 140. I opened it up and found this.

The picture that T-Bone posted is quite common.
I just remove the rubber ring and trash it, doesn't seem to make any difference with or without it.
