If Your Engine Overheats
In any of the following situations, you can reduce the potential for overheating your engine by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, put transmission in NEUTRAL, but do not increase engine idle speed.
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum heat, the mode control to floor and the blower control to high. This allows the heater core to act as a supplement to the radiator and aids in removing heat from the engine cooling system.
