..... really ... do ya ?Here is a pic of the temp gauge. I think this is getting to hot.
What does the manufacturer of the vehicle have to say about such a reading ?
Since the area on the gauge behind where your needle is, in the picture, is NOT red I wonder if that might mean something .... and have some "hidden significance" ....
(FWIW, per the service manual, the engine temperature is considered to be within normal operating limits up to 250 degrees F)
Really ..... izzat right ?This was on the highway. The temp swings more than 50 degrees in a short amount of time. This can't be good for an engine.
Hmmm ..... funny .... cause in the winter - when it's around 0F outside - my coolant temp sometime swings as much as 180 degrees (F) in a fairly short time ....
There are a number of relevant questions that no one has bothered to ask in this thread, that relate to, and have some bearing on your "issue":
1. Where are you located ? (MN ?)
2. What is the ambient outside temperature when you observe this "overheating" ? (your MFD appears to be showing an outside temp of 90 ..... which is kinda warm ...)
3. What is the GVW of your vehicle ? ..... how heavy is it loaded ? ... ever had it weighed ..... since you stuck all that junk in there ?
4. What highway speeds are we talkin' about here ? (I see significant differences in coolant temps, in the summer, as speed goes above 55 mph .... 70 mph can cause the vehicle to run much warmer, depending on other factors)
IMHO, from your description, what you are seeing is absolutely normal behavior .... I see it on my '06 2500 all the time (and you likely have a higher GVW vehicle - cab chassis - with the same engine ... that is working harder) ..... when I am running in high(er) ambient temps, at high(er) rates of speed, (running in 5th will make the engine work harder - since it is an overdrive), with the AC on, and with a high(er) payload ......
The evidence that cooling system is working properly is that it cools it right back down - when the load on the engine is removed (going back up at the light is because there is reduced airflow, due to the vehicle not moving) It will be less prone to cooling off at higher ambient temps.
Having said all that, as stated earlier, fan clutches can and do go bad ... and radiator's do clog up - in fact, I had a friend with an '05 that had it happen.
