135,000 on 09 rambox 1st major problem..so.so . Sunday the temp started to rise and I pulled off the road . I let it cool, looking over everything ?? started back up and turned on the display so I could read the temp. The numbers would go uo 220-225- 238- and so on , then stop and go back to normal 195 .... It did this 3 or 4 times ??? Got it home and took it in to the dealer this morning ... Did the same thing going to dealer , rise up and fall back very quickly .. The service tech did get to see it move .

Now is it the thermo stat or electrical issue ????

 

Sounds like a sticky thermostat.

 

I had that issue with a Neon, turned out to be a relay for the A/C fan in the front, it would increase the speed of the fan when the A/C was on. It was overheating and when they changed that was all set. Good Luck but I bet if you are paying you could find a cheaper heating and cooling or rad shop to check it out. Dealers are so expensive.

 

Dealer called and it was the thrmo stat and a seal near the elec. temp . The max care paid for the rental . I have the 100.00 deductible. Good warranty so far on Max Care

 

Not bad for 135,000. if this was your first major problem. Glad to see the ram going over 100,000.
thanks for the update.

 

i agree with Mike. good to see a 4th gen hit 135k

 

Got the truck back today, part of the gasket from the thermo stat , and the temp sensor . 2 days in rental ... 100.00 deductable ... max care was good to me ..
