Keeping your car’s engine at its temperature is key, both for safety and to extend its useful life. But when the heat hits, sometimes you have to find some tricks so that the heat does not do its thing.
If you have been driving for many years, it is very likely that you already know the effects of overheating on your car engine. Something that is mainly due to the archaic cooling systems that older cars had, as well as the possibility that they would break down en route, generating that famous cloud of vapor that usually accompanies a triggered thermometer. However, despite improvements in technology, heat is still a problem for our engine. Even more so in a country like Spain where it is not uncommon for temperatures to exceed 40 degrees. Therefore, having a few tricks up your sleeve so that scorching heat does not make its own in the engine of our vehicle is not a bad idea.
Check the antifreeze
Although its name reminds us of cold, the truth is that antifreeze is suitable both to be used in conditions of cold and extreme heat. In fact, this liquid also absorbs excess heat from the vehicle’s engine and ends up liquefying, after turning into vapor, in order to reduce the temperature of the car. Therefore, in addition to looking for the best antifreeze ( In this link you can find some purchase options ), according to our needs, it is also key that the level of this vital liquid for the engine is always controlled.
This control is carried out visually on the tank located in the engine, being very important that this level is correct. It is best to fill the reservoir near the F mark, of Full, so that the engine has more fluid to cool down. It is also advisable to check the liquid frequently if you do many kilometers in summer, being advisable to do it every two weeks, more or less. This review should always be done cold, so as not to get false readings in the process.
Replace the antifreeze when necessary
Although many people do not, as with oil, it is also necessary to change all the antifreeze in our engine from time to time. This liquid has a certain shelf life, in which it gives its best result. When this useful life expires, the antifreeze begins to lose its properties and to evacuate heat worse. In general, there is no set timeframe to make this change, beyond the one offered by the refrigerant or vehicle manufacturers themselves. What is convenient is that we do not spend more than five years without changing the fluid, also proceeding to replace it when we see that it loses its original color or that it begins to show traces of other fluids or excess dirt.
Clean the radiator
The radiator is one of the key pieces in the cooling of our vehicle. This is where a good part of the heat is transmitted to the coolant but also where it cools, mainly due to exposure to ambient air during filming, as well as the effect of the fan that is included in its rear part.
A clean radiator will always do its job in a more efficient way, so removing dirt, insects and other elements that may have on its surface is another help to reduce the operating temperature of the vehicle. A process in which we can rely on air or water guns, always used gently so as not to break anything, or even a cloth or similar if the location of the radiator and the available space allow it.
Change the oil
In general, the motor oil that the manufacturer usually recommends is usually the most suitable for our vehicle. However, in very hot areas, this oil can be too fluid and affect the way the engine cools and lubricates. This is what happens with 5W30 oils, whose maximum operating temperature is around 30 degrees. In very hot environments, this oil can lose more quickly than usual, so it does not lubricate well and does not cool the heat as it should.
So if you regularly drive in very hot areas, you may be interested, after consulting the manufacturer or your trusted mechanic, to switch to a slightly denser oil, which cools better and maintains the stability of the lubricating layer better. time to shoot.
A very important aspect so that the engine does not overheat more than necessary in summer is to drive consciously. This driving mode is close to the so-called smart mode or economic driving that we were taught in driving school. A procedure in which we will always circulate in the highest gears that we can, without overusing the engine revolutions.
Let’s think that the faster the motor turns, in terms of revolutions, the greater the amount of heat generated and the greater the effort required to cool it. So it does not make sense to circulate in fourth gear at a high speed, when we can circulate in fifth gear at a much more bearable pace by the engine.
Filters matter too
We have already talked about the importance of cleaning the radiator and the cooling system, but as a final tip we also want to remember the importance of keeping the rest of the engine filters in good condition. Of these filters, the main one is the air one. A clean filter allows the air entering the engine to be free of dust and dirt, generating more efficient combustion and not overheating the engine. If we introduce dust, dirt or dirt into the engine, this will affect its operating temperature.
The same happens with the rest of the filters, such as those for oil or fuel, which must always be in good condition, to guarantee the smooth and efficient operation of the engine.
