In over 45 years of commercial driving I have noted that is is normal for engines to rise in temperature when under load and to cool down when not. The hills in the east do not tax an engine very much but out here in the West you will find that they do and it is normal for the temperature to rise several degrees when under load, sometimes as much as 20 or more. They are designed to handle this.
