It sounds like you may have a coolant leak or possibly a blown head gasket. If the engine is overheating it will shut the AC down to try and protect the engine.

Here is a guide on overheating and the casues

Here is a guide to find coolant leaks.

This will have you test for a blown head gasket.

If everything checks out okay it will probably be the ECT(engine coolant temperature sensor) if it's out of range the cooling will either run all the time, or not at all. May or may not set a codes.

Please let us know what happens.

Cheers

Thanks for the fast response. I will need to run some tests to see what's going on and will get back to you. I hear the fans running so I know that's not it.

Okay I run the tests you suggested (great guides BTW) and the engine came up with a blown head gasket (bummer) so I will have the work done and keep the car becasue this is the first problem I have had with it. It will cost me about $900.00 at the shop.

Thanks for your help 2CARPROS! I love you guys

Having the same problem with my 2007 TOrrent. In addition to the engine light coming on. The A/C off. The temp gauge does not move. But in very cold weather the vehicle completely shuts down. I need to pull off the battery cable to re-set before I can start it again. It has happened a couple of times and only in really cold weather.

We must get to the bottom of the over heating which is job 1. Check out this guide to help you find out what's going on.

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.

Any suggestions?

I also turned the A/C on while I was choking stuff after returning while it was idling and the a/c blows cold.

One of three things comes to mid for me. First is a stuck or missing thermostat to the engine which will cause the engine to not warm up. Here is a guide to help you see what you are in for when checking the thermostat.

https://www.2carpros.com/articles/replace-thermostat

The next thing is the engine coolant temperature sensor needs to be replaced becasue the sensor is not reading right it could be affecting the gauge and the computer warning system. Here is a guide to show you what you are in for when changing the sensor out.

https://www.2carpros.com/articles/coolant-temperature-sensor-cts-replacement

The final test would be to check for w blown head gasket even though there is no coolant in the oil it could be still allowing exhaust gases to enter the cooling system.

Here is a test for that as well.

Please run some tests and get back to us.
