I have this same problem but with a car I have not bought yet, I will be paying for it tomorrow and I wanted to see if anyone else has this same problem. This 2007 Torrent 2 wd has the Engine Hot/ AC OFF, the engine temperature gauge goes all the way up and then all the way down when starting the car as it should but then does not move after, It looks like the engine is not warming up. The fans both come on, there is no oil in the antifreeze, there is no antifreeze in the oil, the 3.4 L LNJ V6 engine runs smooth and I felt no loss of power.I see no leaks under the car or in the engine compartment, the coolant is full.
After driving 10 minutes City, stop and go, from zero to 45 mph, and then 5 Miles on the Highway and 65. MPH, Temp Outside 45 degrees, Night time conditions, returned to the house, engine hot ac off still on and temp GAUGE on zero, popped the hood without shutting down and the engine is not over heated, Hoses return and to the radiator are warm but not too hot to touch and hold. The antifreeze fill is on a satellite tank, the fluid does not circulate there so I cannot check visually circulation, there is no bubbles nor disturbance or Oil in it though.
So now I am checking to see how this can be fixed and how it will effect my pocket book, $ wise. I want the gauge fixed even if this warning cannot be because my wife will be driving this car and she is NOT going to watch for signs or overheating manually of that I am sure.
I also turned the A/C on while I was choking stuff after returning while it was idling and the a/c blows cold.
