I've noticed on the highway (mostly when overtaking) that my coolant temperature is climbing to 238º+ and then coming back down when I let off. I really only noticed because (although I wanted to and I just didn't have the time) I never did the FORScan mod to show the temperature and when it got that hot it would display the temperature until it was below about 220º and then it would disappear again. It makes sense that under load the engine would heat up, obviously, but I don't know how much fluctuation to expect.

Is this any reason for worry or a sign of something coming down the road or totally normal?


Also here's another picture of the truck (featuring my back-up masks hanging from the rear view) at the beach-- because what thread is complete without a nice picture?
