Why does the coolant light go on when the tank is full?
Your problem also be a faulty coolant level module. Check the wiring to be sure nothing is loose or corroded. These are some of the possible causes of a coolant light going on when the tank is full. You’ll want to take your vehicle to a qualified repair location to diagnose and repair your problem if you can not easily diagnose it yourself.
What happens if your coolant sensor goes bad?
A bad coolant sensor may cause a decrease in fuel efficiency or it may also cause the vehicle to fail your emissions inspection. It is likely that the problem may be a loose, corroded, or faulty connection and not a problem with the sensor itself.
When to replace a car coolant light sensor?
If your car is older, the sensor has deteriorated with time and may be failing but not entirely failed. It is not a bad idea to keep an eye on your sensor’s readings. Replacing a sensor that is starting to show extreme signs of age and wear can prevent future problems.
What does a crack in the coolant light mean?
Your coolant light might be signs of a more major engine problem. When you get a crack in the block or the intake gasket you will leak coolant and oil, usually slowly at first. You may not notice the difference at first, thinking that your tank is full. A repair to a cracked engine block or head gasket is an expensive repair.

What causes a car coolant sensor to fail?
Sensor Problems. Your sensor may fail or it may simply give a bad reading. A bad coolant sensor may cause a decrease in fuel efficiency or it may also cause the vehicle to fail your emissions inspection. It is likely that the problem may be a loose, corroded, or faulty connection and not a problem with the sensor itself.

When does the coolant light come on on a Saturn Ion?
On the Saturn Ion, as with many other General Motors cars, there is a multifunction coolant light on the dashboard. This light comes on to inform the driver of overheating or low coolant level. When the coolant temperature sensor notices a higher-than-normal temperature — between 180 and 210 degrees Fahrenheit — it turns this light on.
When does the coolant light come on for a low temp?
This coolant light also comes on for a low coolant level. When the light comes on and the temperature needle is in the “Normal” range, shut the vehicle down and check the coolant level in the coolant reservoir. It should be between the “Min” and “Max” lines.
What to do when your coolant level is low?
This coolant light also comes on for a low coolant level. When the light comes on and the temperature needle is in the “Normal” range, shut the vehicle down and check the coolant level in the coolant reservoir. It should be between the “Min” and “Max” lines. Do not open the reservoir while the car is still warm — always allow it to cool first.
When does the coolant temperature sensor turn on?
When the coolant temperature sensor notices a higher-than-normal temperature — between 180 and 210 degrees Fahrenheit — it turns this light on. Once this light comes on, check the temperature gauge and shut the vehicle down if the needle is near the “H.”
