I just got a 14 summit aand i drove in the mountains ..It seems that the temp gauge goes up to the red line but not into that zone ..is this normal..anyone experience the same thing..

Depends on the circumstances surrounding your driving in the mountains...

- Which mountains and their location?
- What type of road you were on... interstate or winding switchback?
- Elevation you were driving at?
- What % grade was the ascent and the time or distance it took to get to the top?
- Your speed while ascending... slow or closer to highway speed?
- What was the outdoor air temp?

this trip is in az there are many grades as long as 3 miles and as steep as 8% the temp started out around 90 and ended up around 75 ..you start at sea level and 80 miles later you are around 7000 ft the road is a great 2 lane and it does a lot of winding streaches to its a 2 hr drive and I wasnt in a hurry so I babied it..I have a 05 liberty diesel no problems with the temp on it and have driven this route many many times...I was wondering if I might have a air lock coolant level was correct and the fan does run..open to any help

I would think you would only see a slight increase in temp under a load like that, ambient air temp is well with-in the cooling system design temp.

Did it smell hot ? Or did you notice any unusual smells ?

Either way I'd take it to the dealer could just be a gauge issue, but it shouldn't get that warm in the conditions you indicated.

I agree, I don't read anything here in his driving conditions that would indicate that being the cause.
