I need some suggestions here as to what the problem could be. I believe the thermostat or the sensor could be bad. Has this happened to any of you? The car never ran hot. This started this weekend. I had to put 500 miles on it to get back home. The low coolant sensor on the DIC kept coming on and going off. The temperature guage showed the temp to be normal. Bummer. I made sure it had plenty of coolant, but I added some water just in case and this did not good at all. The radiator was full. I pulled the cap off when it cooled to make sure I did not have a stopped up overflow hose or something.

Give me some input here please.

I've had this problem when i first bought my car, most more than likely you'll need to remove the coolent sensor, it is located on the right hand side of the rad, about halfway down, i pulled mine out and cleaned it with some liquid wrench and a soft brass wire brush and that cured me of my problem. There is a little steel piece in the middle of the sensor, sometimes gets built up on it. Good luck, and remember do it when the engine is hot, and get a friend to hold his/her finger on the hole were the sensor pulls out of, unless you want to drain your fluid, totally up to you. Worst case senario, you will have to replace the sensor. Not sure on the cost. Once again , good luck.

Yup, mine does this too, although I haven't bothered to clean it yet. Seems to be a common problem.

Be careful taking the sensor out. It has two small clips molded on to it to keep it in place. I broke one of mine. The dealer wants $60 for a new one. I am getting a new one from Advanced auto parts for $13. It had some gunk on the top of it. I guess that could have been causing a problem. I don't know. I have to check it out further. I needed a new one anyway. When they installed it at the factory they crimped the second O ring so it just had one good one holding the coolant in.

The sensor had to be replaced. I had to get it from the GM dealership, $58 plus tax.
