Temporary Rise in Coolant Temperature
I was pulling a small single axle trailer up a long hill with my F350 diesel today and my Edge Insight monitor showed a coolant temperature of 288 degrees. The needle on the OEM dash gauge did not go up. After awhile the temp went down to 199 degrees which is pretty normal for summer.
Since my factory gauge didn't show a rise in temperature, I'm thinking the Edge Insight monitor was malfunctioning (unless an 80-degree rise in temperature doesn't register on the factory gauge). Anyone else ever experienced this? Thanks.

The dash temperature gauge is not very responsive - it is more like a switch. I sure would have thought it would have moved some if it were that high in reality though. I would think the only thing that would explain a spike like and then a dip back to normal (if it is real) would be a sticking thermostat.

When my egr cooler was going out I was pulling my 38' tt and my temps got up two 248 or so, the factory gauge did move to the red, but it didn't do so untill I hit the 248. It was showing normal the whole time untill I hit the 248. Then went from normal to max at once. That's why I say never go by the factory gauge.
