Engine Overheating {CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine. Occasionally check the coolant level in the radiator. For information on how to add coolant to the radiator, see Cooling System on page 5-32. There is a coolant temperature gage and a warning light on the instrument panel that indicate an overheated engine condition. See Engine Coolant Temperature Gage on page 3-38 and Engine Coolant Temperature Warning Light on page 3-37. In addition, you will find an ENGINE OVERHEATED IDLE ENGINE and an ENGINE OVERHEATED STOP ENGINE message displayed on the vehicle's Driver Information Center (DIC). See DIC Warnings and Messages on page 3-52 for more information. Pressure Cap Notice: If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. See Engine Compartment Overview on page 5-14 for more information on location. 5-29
