2012 Mitsubishi Eclipse Owners Manual - Engine overheating



Engine overheating

If the engine coolant temperature gauge indicator moves to the “H” (hot) position (red zone), the engine may be overheated. If this happens:

1. Stop the vehicle in a safe place. Turn on the hazard warn- ing flashers.

2. With the engine still running, carefully raise the engine hood to vent the engine compartment.

3. Check that the cooling fan is running. If the fan is not turning, stop the engine immediately and contact an authorized Mitsubishi Motors dealer or a repair facility of your choice for assistance.

4. If you see steam or spray coming from under the hood, turn off the engine.

5. If you do not see steam or spray coming from under the hood, leave the engine on until the temperature indicator on the instrument panel moves below the red zone. When it is in the middle of the normal zone, you can start driving again. If the indicator stays in the red zone, turn off the engine.

WARNING! ● To avoid personal injury, keep hands, hair, jewelry

and clothes away from the cooling fan. The cooling fan can start at any time.

WARNING! ● Before raising the engine hood, check to see if there

is steam or spray coming from under the hood. Steam or spray coming from an overheated engine could seriously scald you. Do not open the hood until there is no steam or spray.

For emergencies

6. When you do not see any more steam or spray, open the hood. Look for obvious leaks, such as a split radiator hose. Be careful as components will be hot. Any leak source must be repaired.

7. If there is no obvious leak source, check the coolant level in the reserve tank. If there is none, or if it is too low, slowly add coolant.

8. If the reserve tank needs coolant, you will probably also need to add coolant to the radiator. Do not loosen or remove the radiator cap until the engine has cooled down.

9. Start the engine, and slowly add coolant, up to the bottom of the filler neck. Use plain water if you have to (and replace it with the right coolant as soon as possible).

10. Replace the radiator cap and tighten it fully. Check the temperature indicator. You can drive when the indicator returns to the normal zone.

11. Have your vehicle checked by your authorized Mitsubishi Motors dealer or a repair facility of your choice.

WARNING! ● Removing the radiator cap could scald you with

escaping hot water or steam. When checking the radiator level, cover the cap with a cloth before try- ing to remove it. Turn it slowly counterclockwise, without pressing down, to the first notch. The pres- sure in the system will then be let out. When the pressure is COMPLETELY LET OUT, press down and keep turning the cap counterclockwise until it will come off.
