Check your coolant first, if it's not low then replace coolant level sensor
i have found that with my 97 sable the low coolant light comes on when my oil is low. same as your car can run hot when your extremely low or out of oil
it is low or out off coolant.
Add coolant to the reservoir. If the low coolant light still stays on, replace the low coolant sensor.
If it is the low coolant light, it may mean your coolant is low. If it is not low, it may be the low coolant light sensor malfunctioning.
Reservoir light? You mean low coolant light. Low coolant level means the reservoir is low of coolant.
Low coolant level.
when u have low coolant
Coolant is low or a sensor malfunction.
Check your coolant sensor for built up sludge, or the sensor may need replacement.
when the engine is cool, check the anti-freeze level. it may be low.
When the low coolant warning light comes on and the car has enough coolant, it usually means there is a problem with the coolant level sensor system. The sensor may need to be replaced.
