the sensor is faulty. Located half way down the side of the radiator.
Low coolant in coolant recovery tank or radiator or defective sensor
Sounds like the low coolant warning light Check the coolant level
If you are talking about the low coolant light then it is just low of coolant. Add coolant to the recovery tank. If you are talking about the coolant temperature light, then the engine is overheating. You may need to have the cooling system serviced. Drain the coolant and flush the system. Install a new thermostat, and add a 50/50 mix of antifreeze and distilled water.
Either your coolant is actually low or you have a coolant sensor bad.
Believe it or not. ADD COOLANT>
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
The check gage light comes on if the engine coolant temperature is too high , the oil pressure is too low , or the gas gauge is at or near empty
This is usually due to a faulty sensor in the coolant bottle. It could also be a bad connection. I had same thing happen to me on trip from Missouri to Wisconsin at night time. Stopped to check and nothing low It was connection at sensor Squeezed it with plyers and havent had problem again for over 5 years now

Defective sensor? Usually in coolant recovery trank
