The coolant level sensor is located on the radiator. If you are looking at the engine from the front of the car it will be on the left side. There will some kind of clip holding it in the radiator. Removed the clip and pull the sensor out. You will lose coolant so try to swap it out quick or drain some of the coolant out. Once new sensor is installed, install clip to keep the sensor in place and reconnect the wires to the sensor. Crank the engine and make sure the coolant level is full. This should correct your problem.

It NEVER was the camshaft sensor! Unless, you've removed the engine lately, which I doubt.
RUN to Advance Auto Parts and buy a can of "SeaFoam" and add to your gas tank per instructions...drive at least 100 miles and the problem should go away...IF it doesn't you'll have to replace the O2 sensors in the exhaust system...Any good mechanic should be able to do this for much less $$ than the dealership DO NOT go to the dealer for repairs!

SOURCE: AWD Light stays on
3rd dealer stated that the problem was in the differential pump valve, when the temperture sensor was giving a false reading and disconnecting the rear wheel drive. Replaced with GM Part 88896067, and it solved the problem. Mechanic stated that if it is ONLY the AWD light, then this is usually the problem. If the ABS Disable light also goes on, then it is the harness on the wheel sensor.

Hi usually the symptoms your having are a result of the oxygen sensor(or lambda sensor for its technical name) being at fault.
now the reason it points to this being at fault is that it only starts working when the engine is near normal temp then if the car wont start till its cooled down then this is because the sensor then stops working when its cooled down so your car will run again until it gets hot,
you need to check where the sensor is located in the exhaust if it comes before the catalytic converter then the chances are its the sensor at fault but if it comes after the cat then it could be the cat that is at fault.
my best guess would be the sensor as your car is playing up exactly as if this sensor was not working.
i hope this is some help to you
