The low coolant message on your 2004 Saturn Ion indicates that the engine coolant level is below the minimum required threshold. This could be due to a leak, evaporation, or insufficient coolant added during maintenance. It's essential to address this warning promptly, as low coolant levels can lead to engine overheating and potential damage. Check the coolant reservoir and refill it if necessary, and investigate any possible leaks.
Low engine coolant
The light you are describing indicates low coolant level in the coolant reservoir.
The oil life message means your car hasn't registered the fact that you've had your oil changed.
If your 2004 Saturn has a window that won't roll up, this could be due to something blocking the window. It could also mean that your electrical system is damaged.
Engine coolant temp low, thermostat failed.
I believe you have lost your engine coolant
Engine coolant Sensor is bad. I have the same error on my 2005.
First check the coolant level, a coolant leak would cause a heater to stop working- assuming you mean the blower is blowing but it isn't hot. A stuck thermostat will also cause you problems with your heat.
If you mean coolant temperature sensor.... ITs on the driver side, behind the alternator. Must remove the alternator!
it could be an electrical issue such as ignition module or sensor
It is the same as a low collant message. The fluid level in the expansion tank is low. the tank is under the hood and located next to the fender on MB's. As a note, never service when the engine is hot.
