With the onset of summer heat, drivers of all stripes have one more headache. Machines began to overheat. Along the roads, it is increasingly possible to meet a motorist near the hood of his car, from the bowels of which thick steam is pouring out. And, as you know, engine overheating does not lead to anything good. Especially if the car owner missed precious time and, as it is called, missed the moment, informs Ukr.Media.

Heat, traffic jams and delayed problems in the engine cooling system are ideal conditions for antifreeze to boil. It's no secret that this can lead to harmful consequences for the engine, which will require serious cash infusions to eliminate them. Let's omit the fact that it is necessary to monitor the car. And let's go straight to what to do if the car owner didn't keep up and his car “boiled”.

Antifreeze boils for several reasons. For example, the thermostat can jam or an air jam has formed in the system. And the low level of coolant may be to blame for everything. A faulty fan, a clogged radiator, or a failed coolant temperature sensor can also cause the engine temperature to creep up. In general, be that as it may, modern cars know how to recognize overheating, and immediately inform the driver about it with the help of a control lamp or a sound signal. What to do if this happened to you?

Overheating of the engine is dangerous because it simply starts to run at temperatures critical for the metal. At the same time, leaks are formed in the head of the cylinder block, where they should not be. And if you miss the moment, the engine can jam altogether. Therefore, when standing in a traffic jam, be sure to look at the instrument panel in the area of ​​the engine temperature scale. If she gets to the red zone, your quick actions will prevent the situation from developing in a bad way. If the needle of the device is in the red zone, then you should immediately turn on the heater to the maximum. It will be hot, but it will allow excess heat to be removed from the underhood space into the cabin. The temperature will start to drop — and this is your chance to get out of traffic in any free direction to find a technical center.

​If you miss the moment and the antifreeze has already boiled, you need to quickly pull over to the side of the road and turn off the engine, leaving the ignition on to start the interior heater — so the excess heat will be removed from the engine faster.

A here you should not run and open the hood and the expansion tank cover at once. It will be better if they remain closed for a while. Otherwise, you may be injured by hot steam. In addition, breathing ethylene glycol vapors is far from useful.

After 10-15 minutes, it is quite possible to open the hood and look into the underhood space. Some malfunctions of the cooling system will be visible to the naked eye. For example, a pipe burst or disconnected. If nothing is found, then you should add antifreeze to the required level and follow the search for a service station, where professionals will understand your problems. At the same time, it is necessary to open the lid of the expansion tank through a rag and very slowly in order to release excess pressure in the system. Also, when moving, you should carefully monitor the temperature. And at the slightest movement towards the red zone of the sensor, stop and let the engine cool down.
