The engine overheating is able to lead to significant damage to its parts operating in rigid temperature conditions. In the summer, the risk of this problem is very high. It is important for the driver to have an idea of how to find out the overheating of the car engine in advance in order to avoid destructive consequences and the need to deliver the vehicle home or to the service on the evacuation. Even short -term work in high temperatures often becomes the cause of the breakdown of the GBC and various deformations. Oil -adole caps, piston rings, piston themselves, aluminum cylinders and GBC are especially sensitive to overheating.
Signs of engine overheating
The presence of an appropriate signal on the dashboard issued by the on -board computer, or the arrow transfer to the red region of the scale.
If in an extreme situation to cool antifreeze the driver turned on the stove, and the hot air suddenly stopped coming from it, then this often indicates a boiling fluid and the formation of air traffic jams or the presence of leakage and a decrease in the level of coolant.
A characteristic voiced knock when exposed to accelerator pedal. This is a certificate of detonation that occurs during uneven combustion of the fuel -air mixture from contact with excessively hot walls of the combustion chamber.
The drop in engine power. When you press the gas pedal, an unusual “sluggish” acceleration with an increased noise coming from the engine compartment occurs.
What to do if the motor overheat?
If one of these signs is detected, you need to turn to the sidelines and allow the power unit to cool for about 15 minutes. In this case, it is recommended to raise the hood. The radiator’s electric fan at this time can be kept on.
If there is no possibility of stopping, it is necessary to turn on the heating of the cabin to full power in order to increase the area of scattering the heat released by the engine into the cooling system. At the same time, it is important to turn off the air conditioner to save the internal combustion engine from additional load. To cool the salon in such conditions, it is better to get glass.
When the motor cools down, it will be possible to open the radiator cover and add the coolant if there is a lack. If traces of oil are detected in antifreeze, often indicating a break in the gasket of the HBC or the appearance of cracks in the engine, and here it is extremely desirable to continue the way already on the evacuation. Otherwise, antifreeze enters into a lubrication system or the occurrence of a hydraulic jacket is not excluded.
The reasons for overheating
Lack of coolant. She can boil or dragging through the damage to the tubes.
Jamming the thermostat in a closed state.
Pollution of the radiator grille with oil deposits, down or dirt.
Electric fan malfunction.
Damage of the pump
Timely elimination of these reasons will help minimize the risk of a problem. If the engine worked in an overheated state for several minutes or more, you should definitely visit a service center for thorough diagnosis.
