I have noticed a temperature increase lately, not sure why. I have a bullydog pmt so i am able to monitor my temps well. I frequently drive to and from las vegas going thru death valley. It seems before i did a lot of driving my coolant temp hung around 186-202 degrees. lately it has been running hotter, in the high 190's, and going thru death valley last time i had to slow down to 60mph to keep it below 220. How hot is too hot? it got as hot s 222. could anything be damaged? does anybody have idea what it could be? Thanks.:dunno:

203* is supposidly the optimum temp for a diesel.

So if I am at 210 on my coolant then there is a problem? it will definitely push up to 220 if i kept on it. It takes a long time to cool down too. weird thing is that my stock coolant temp gauge didn't move at all in the hot direction. it warms up and stays right in the middle. thanks for the replies, I am pretty new to the diesel and just don't quite understand everything:thumb:

You should hear the fan kick on at 210*. 220* is too hot in my mind, but I doubt that 222 for a little while would cause damage. You may have a bad factory temperature probe. If it is definitely running hotter than it used to, it is worth investigating and correcting.
