Ok The car has 87K miles on it. I just had the water pump replaced because it was leaking coolant. The light comes on when I start the car and stays on until the Temp gage reads around 180 degrees. I have been keeping an eye on the coolant level and it has not changed. Do I have a bad sensor or is there an air bubble? I also put stop leak in prior to getting my water pump replaced. Could this be causing a clog in the system somewhere? Please help me diagnose this and any suggestions on how to fix would be most appreciated.

You people are awesome. Thanks for all the answers so far and the ones that are still coming. I will pick the best answer after I solve the problem.

The coolant sensor shouldn't be bad, it just needs to be reset. The nearest Chey dealership can do this for you. Once it's been reset and eventually comes back on then there's a problem which the dealership can detect with a little hand held system scanner that plugs into your car.

I own a shop, and think you have a leak in the system some place. As for the light staying on a year, that sounds like a faulty sensor in the bottom of the recovery tank (where you add coolant), and it is either not floating up (stuck), or it is just no good. When adding coolant to your engine, you must keep in mind two things; One, the type of coolant you put into the system does matter, and only use the coolant the manufacture recommends or its equivalent. It should say right on the container "For all types of vehicles" if its the right one. Two; Pay attention to the marks where the level is to be filled to. Too much and it will throw it back out when the engine gets up to normal temperature. Coolant expands & contracts in the system, and if you don't leave enough room for it to expand, it will kick it out the overflow. If a system is allowed to get too low, it will pull air into it, and this air will have to be purged from the system, or it will cause hot spots, and an overheating condition. The best advice anyone could give you is to have it pressure tested along with the cap too. This way you will know right away what the problem is. There are many things that can cause this problem, and finding the cause can be difficult at times. The pressure test will find it 99% of the time. Have this done, and you will know what to do next. About the only thing a pressure test won't find is a sticking thermostat, so you may want to have that replaced anyway. Glad to help out, Good luck!!!

If you coolant level is ok ,get a rubber hammer or something and tap on the coolant tank. These sensors have a habit of sticking after work is done on the coolant system. The stop leak probably stuck it.

Ok, check the sensory rotar before flushing the coolant. Apply a compound known as 'terrier soluable' into the coolant mainframe. Be sure to only fill it at the allowable tempature. From there, run your engine for a good 2 hours, turn off, let cool, then buy something known as 'mercury saline' to tighten up any cracks.

if the coolant level is good then the sensor may be bad by not reading the right temp at lower readings Replace it its usually cheap if it dosent work then the problem might be in the ECM or the instrument cluster

Hey we have the same car but I have double the miles and she's still running like a beaut! Its probably a sensor problem since it does go off at times. Get a diagnostic reading.

I have a 2000 Impala.
I wouldn't worry about the lights. All GM cars have those glitches. As long as your temp is ok, and you're not leaking anything except water off the AC unit, you're fine.

is the sensor on the side of the radiator or the coolant reservoir.is it plastic or brass type.the sensors are cheap.jus replace them.disconnect your battery terminals for 15min.reconnect add fluid and enjoy...
