Over heating causes brutal and disastrous engine failure. Some engines are more susceptible to overheating. The engines are capable of working within the temperature range of 195 to 220 degree F. A uniform temperature is required for the proper functioning and performance of the engine.

Engine over heating occurs mainly when the gasoline engine starts to ignite. The car engine will start losing power under load as the mixture of heat and pressure exceeds the octane rating of the fuel. If the ignition problem still continues then this might damage the engine’s rings, pistons or rod bearings. It can also cause pre-ignition.

The causes of overheating can be anything that diminishes the cooling system's capability to absorb, transport and disperse heat. Some of the reasons can be coolant leaks, poor heat inside the engine, defective thermostat, inadequate airflow through the radiator, slipping fan clutch, inoperative electric cooling fan, a collapsed lower radiator hose, an eroded or loose water pump impeller, or even a defective radiator cap.

Tips to make the engine cool:

• Turn off the air conditioner because it makes the engine work a little harder. But it’s recommended to turn the heater on, as the heat will escape from the engine.
• Turn over the climate controls to vent. Switch on the heater as well as the fan. The heater works by using extra heat from the engine to heat the incoming air. So turning the heater on full-blast pulls as much heat as possible off the engine and blows it into the cabin of the car.
