Cooling system and engine operation
The cooling of the power unit is one of the elements due to which the car can run smoothly. Insufficient coolant levels or even small air bubbles can lead to serious malfunctions that can lead to costly repairs. That is why you should know how to quickly and efficiently bleed the cooling system, so that in case of problems, minor malfunctions can be quickly eliminated. Of course, as a novice driver, you may not even realize that the cooling system is keeping the engine running properly.. But that's not all, because you yourself will also be responsible for maintaining the correct temperature of the drive unit.
Symptoms of air in the cooling system
Taking care of your cooling system isn't just about supplying good quality coolant. This is important, but if you think that just filling it in the tank is enough, then you are greatly mistaken. Sometimes it is necessary to bleed the cooling system. Engine temperature should be between 90 and 150 degrees Celsius. When the temperature is too low or close to the upper limit, you can almost be sure that something is wrong with the cooling system. This is one of the main signs of the presence of air in the cooling system.
The good news is that you can test it out and make your own car cooling. The easiest way to do this is if the car is equipped with air vents that are located in the thermostat. Then it is enough to unscrew the plug from the tank a little and let the air escape from the system into the expansion tank. If you do not have time for this, contact a mechanic. It is very important not to neglect this step. Otherwise, you will expose your vehicle to engine damage. Piston seizure or poor lubrication may occur.
How to recognize air in the cooling system?
When it comes to air in the cooling system, the symptoms are visible to the naked eye. The signal that you will immediately notice will be the appearance of smoke. In addition, a coolant leak will be visible. Therefore, it is worth walking around the car from time to time and checking if nothing is dripping from it, but it is best to regularly look under the hood.
As for pumping the cooling system itself, it will not be a very difficult procedure. If you follow a few basic rules, the air in the cooling system will quickly stop bothering you.
How to bleed the refrigeration system yourself?
The most important thing when bleeding the cooling system is to make sure that the engine and coolant are completely cool. Remember that if the car is warming up and you open the valve, you can get badly burned. There is high pressure inside the tank. Liquid may splatter. If you're careful about how to ventilate the cooling system, don't forget to park your car for a long time with the engine off. Then the temperature will be at the optimum level.
The next step in bleeding the cooling system is to unscrew the nut and start the engine. Then look for air bubbles on the inlet surface of the heatsink. If the liquid gradually subsides, it should be topped up and monitored. You will repeat this action until the bubbles stop appearing. Remember to add the same liquid as before. In addition, it is not recommended to add plain water to the tank.
Air in the cooling system - prevention and prevention of problems
Do you want to avoid getting air into the cooling system? Don't forget to check its condition regularly! At the same time, it should be carried out regardless of whether you notice temperature drops. Most often, system control is carried out during other service activities. So if you haven’t contacted a specialist for a long time, then you should check the radiator, heater and fluid yourself. Then you will minimize the risk of failure.
The most common malfunctions and failures in the cooling system
It is not said that if you already know how to recognize the air in the cooling system and correctly perform all the actions, then there will be no problems. If you are still unable to maintain the desired temperature, then additional malfunctions may be to blame. Usually there is a coolant leak. This may be the result of a damaged radiator or hose leak. Fortunately, these are not serious failures, it is enough to install new components.
Worse, when there is no leak, but the liquid in the tank is still depleted. This could mean liquid getting into the oil, which is a serious and costly problem. Then you should immediately go to the workshop, where mechanics not only know how to get rid of air from the cooling system, but they can also identify, for example, a dirty radiator or other easily fixable malfunctions. Too low or too high engine temperature can cause serious damage. That is why it is so important to take care of the cooling system. Don't forget to air it regularly. This is a simple action that will allow you to avoid serious problems.
