Causes of overheating of the engine of a car can bother every owner. It can be caused by increased air temperature, in the summer time, constant stay in traffic jams on the roads. And as a result – a spoiled holiday or a serious car breakdown. If the engine overheated, you didn’t notice it, and there was an accident, turn the machine in for recycling:

Inexperienced drivers or those who have encountered such a breakdown for the first time will find it difficult to determine the causes of this problem. But there are some indicators that allow self-diagnosis of real problems in the vehicle. 

It should be noted that the engine overheating is not such a harmless problem and may cause such a breakdown that serious engine repairs are inevitably required, and it may happen so that the engine can not be restored.

It is necessary to watch closely the reading of a temperature sensor of a cooling liquid. It will show if there are problems, the arrow will crawl into the red zone. It is necessary to observe carefully the data of the alarm lamp, if necessary to stop immediately and try to diagnose the causes of the alarm.

It is possible to detect overheating of the engine by the sound of the engine or detonation, at the moment of pressing the gas pedal.

A sign of steam in the underhood space is the obvious overheating of the engine. At that a car stop will be just necessary to cool the engine down a little.

Causes of engine overheating

It is necessary to remember that any type of failure does not tolerate a negligent attitude because the consequences may be very different and even very disappointing, and for the car and its owner. Having correctly diagnosed the reason, which caused overheating initially, it is possible to avoid consequently a repetition of this breakdown. The most common causes of engine overheating include:

Desaline leakage – this means that the cooling system is leaky, that is, there is a coolant leak somewhere. This may be caused by cracked hoses, it may have become critical wear and tear on the seals on the pump, perhaps the thermostat has leaked and so on.

Dirty radiator, it is necessary to clean it regularly from different garbage, leaves, scale from water. All this can be done in the service station Autodoctor in Odessa.

The thermostat malfunction. To check for proper operation, it is necessary to warm up the engine and touch the cooling system hose (carefully), or the radiator. If these elements remain at ambient temperature, it is necessary to change the thermostat.

Failure of the cooling system pump also becomes a serious problem if the coolant circulates poorly in the system.

The radiator fan failure also reduces the efficiency of the cooling system and in hot weather can cause overheating.

If overheating occurs, the driver should know what to do and what not to do.
