Overheat
One of the original idiot lights, at least in red, this is the Temperature Warning lights or symbols. The text symbol Hot Coolant Temp (temperature) spells it out plainly. In red, it indicates quite simply that the engine temperature is too high. If you see this light, your vehicle should be stopped and the engine turned off as quickly as possible. Turning on the heater to the highest setting will remove some of the heat as well.
- But first, is one of these truly your symbol?? If yes, then read on below!
- Otherwise return to our main Picture Symbols page and scan again!
Contact your dealer or authorized service center as soon as possible. But, what’s the deal with the second one below? Blue?
In blue, the symbol, which resembles a thermometer placed in water, indicates that the coolant temperature is below what is needed for optimum performance. If the light blinks red then blue, an electrical malfunction in the cooling system is indicated.
Again, contact your dealer or authorized repair center soon.
Finally, shown in yellow/amber, the symbol of the thermometer alone speaks to fuel having entered the engine oil. Run the engine until warm to allow the fuel to evaporate. Also, avoid running at a high rpm as well.
Note that this unlit symbol may appear inside the temperature gauge and have no function other than to describe the gauge it is sitting in.
