Either do to a coolant leak or a failed coolant level sensor.
Check the engine coolant... Is it full? yes coolant level is full
YOU WANT TO BE CAREFULL WHEN DRIVING W/ A COOLANT LIGHT ON THE BEST THING TO DO IS TO CHECK THE LEVEL OF COOLANT AND ADD IF NES. AND OF COARSE KEEP A GOOD EYE ON YOUR TEMP GAUGE..DO NOT OVERHEAT...
Just had the same problem on my Grand Am. It was the water pump.
Your check engine light will not come on because your coolant needs to be changed. The only way to be totally sure why it is on you should get it checked with a computer at a dealer or service station. The check engine light may come on if it is over heating because there is no coolant in it but not if it just has to be changed.
On the side of the radiator, by the filler neck? This is the only low coolant sensor I know of. *Ditto here; There is only one for temp and another for coolant level. Each sets off a different warning light on the dash.
yes
Fill your coolant reservoir and the light should turn off. Do it soon or your engine may over heat.
Low coolant or a defective sensor
The coolant level switch on a 95 Achieva has a sticking problem. If you tap the coolant tank near the sensor the light will go out
Low coolant would be because the coolant is low or the sensor has failed, Check engine light would be because the computer has detected a problem and set a code.
bad sensor
loosing coolant without leaking under the car, so it is burning coolant, mine is staying on and so is engine light and it is also a 99 grand am gt and just happened today :( now we to put upper gaskets in.
