How to prevent engine overheating in hot weather?

Engine failure can lead to serious trouble. An efficient engine, even in summer, should not operate at temperatures above 95 degrees Celsius. What to do and how to prevent its loss?

The hot summer painfully checks the condition of the cooling system in our car. Even Kajetan Kajetanovic will be surprised by the unexpected release of steam from under the hood of the car.

Engine overheated

The main symptom of an overheated engine is that the fluid temperature gauge tilts towards the red area. However, not all indicators are color-coded, so how do you know about this issue?

• Interruption of the interior heating system,
• Distinct smell of coolant in the cabin,
• Swollen cooling hoses
• Steam comes out from under the hood.

Engine overheating is harmful, but will not cause you to stop driving.

Coolant boils

The boiling point of the coolant, depending on various factors, is approximately 100 - 130 degrees Celsius. The sudden drop in pressure after the system is opened will make the cooking process more intense, hence the steam escaping from the machine. It is worth knowing that at the stage when the liquid bursts the cooling system and pours out of it, the temperature indicator usually stops working - paradoxically, but usually shows a “cold engine”.

What could be the reasons for engine overheating?

There can be many reasons for engine overheating. The correct diagnosis must be made by a mechanic. Here are the most common breakdowns:

• The heat pump drive belt is slipped or broken,
• leakage of coolant due to a leak,
• The coolant temperature sensor is broken
• The viscous coupling of the fan is damaged,
• The coolant pump is broken
• The cylinder head gasket is worn.

What to do if the coolant boils while driving?

When the coolant needle approaches the boundary field, it is time to take the appropriate action. Pull over to the side of the road as soon as possible and then turn off the power unit. There are 4 steps ahead to help save your engine.

1. Turn on the heating and blowdown in the passenger compartment at full power, this will help cool the engine.

2. Stop for an hour to cool the engine. You can open the hood, but be aware that hot steam may come out from under the hood.

3. Check the engine coolant level. It is important to ensure that the liquid level is above the minimum.

4. Add water! Remember that this cannot be cold water, it must be at least room temperature. Of course, it is better to add coolant, but one must take into account the fact that when the system leaks, everything will flow out at once.

Never underestimate the symptoms of engine overheating and keep driving at all costs. If you do this, you can destroy the power unit and it will just jam.

If you observe an unstable coolant temperature, you should consider replacing the water pump. It is not worth saving on this element, because its price ranges from 20 to 300 zlotys, and its serious damage can lead to a breakage of the timing belt and you will pay much more!

Therefore, it is worth equipping yourself with a water temperature sensor, whose task is to monitor the temperature of the engine and coolant. Moreover, data transmission to the engine control unit. Thanks to this, it is possible to prevent the engine from overheating in time.
