Overheating
Definition:
When the temperature of the coolant exceeds the normal operating temperature range of the engine, it is said to be overheating. A number of things can cause this to happen. Idling for long periods of time in traffic during hot weather can cause overheating because the water pump doesn't turn fast enough to circulate sufficient coolant through the system. A defective thermostat can stick shut and prevent the coolant from circulating to the radiator. A leak that allows the coolant level to drop can result in overheating. A defective or inoperative cooling fan can cause the engine to overheat. As can a slipping or broken fan belt. If an engine overheats, turning on the heater can sometimes help increase cooling capacity enough to cool it down. In most cases, though, the engine should be shut off and allowed to cool. Running it hot can damage the engine. NEVER open the radiator cap on a hot engine. Steam and coolant can spray out under considerable force and burn you! Add coolant to the coolant reservoir, or wait until the engine has cooled to open and cap to add coolant directly to the radiator.
