Engine Coolant Temperature Gage - Saturn 2004 Ion Owner's Manual

Engine Coolant Temperature Gage

If the engine coolant temperature reaches 253° (123°C)
the CHK GAGE message will appear and a chime
will sound to alert you to the engine coolant
temperature gage. See Message Center on page 3-41.
This gage on the left
measures the temperature
of the vehicle's engine
coolant. If the pointer
moves into the shaded
area, your engine is
too hot!
If you have been operating your vehicle under normal
driving conditions, you should pull off the road and
stop your vehicle, be sure the air conditioning is off,
let the engine idle for a few minutes, then turn off
the engine.
If your engine control system detects a failure in the
engine coolant temperature circuit, the malfunction
indicator lamp (service engine soon) light will come on.
The coolant gage may read all the way hot or cold.
The engine cooling fan will be turned on to protect the
engine and transmission. See Malfunction Indicator
Lamp on page 3-36 for more information.
