Engine cooling system: principle of operation and main components
Your car's engine runs best at high temperatures. When the engine is cold, components wear out easily, more pollutants are emitted, and the engine becomes less efficient. Thus, another important task of the cooling system is to warm up the engine as quickly as possible, and then maintain a constant engine temperature. The main function of the cooling system is to maintain the optimum operating temperature of the engine. If the cooling system, or any part of it, fails, the engine will overheat, which can lead to many serious problems. Have you ever imagined what would happen if your engine cooling system didn't work properly? Overheating can cause head gaskets to explode and even crack cylinder blocks if the problem is severe enough. And all this heat must be fought. If heat is not removed from...

How does the car heating system work?
The sun is setting and the air smells cool. You pause to raise your jacket collar, then quickly walk to the car door and get into the driver's seat. As soon as you start the car, in just a few seconds, the fingers you hold in front of the air vent will begin to feel warm. The tension in the almost trembling muscles begins to relax as you switch to the engine and drive home. Your car's heating system combines the functions of another system to keep you warm. It is closely related to the engine cooling system and consists of the same parts. Several components work to transfer heat to your car's interior. These include: antifreeze heater core heating, ventilation and air conditioning (HVAC) control dust fan thermostat water pump…

Flushing the radiator and cooling system is a simple procedure that you can do at home with a little patience and some basic knowledge. However, it should be noted that if…
Why repairing the cooling system on a European car can be difficult
Repairing the cooling system, for example in the event of a leak, can create various obstacles. Many repairs may involve finding the system's heatsink. Most people think that the cooling systems on all vehicles can be easy to maintain. On the other hand, cooling systems can be tricky to repair when working with a European car. Cooling systems are designed to keep the engine running at operating temperature for optimal performance. In addition, the cooling systems also help heat the cabin for climate control, as well as defrosting foggy windows. The cooling systems on some vehicles can be very complex. On European vehicles, most cooling systems are difficult to work with because the system is hidden or in hard-to-reach places. Many European cars have remote reservoirs...
How does a car cooling system work?
Have you ever thought about the fact that thousands of explosions occur in your engine? If you are like most people, this thought never crosses your mind. Every time a spark plug ignites, the air/fuel mixture in that cylinder explodes. This happens hundreds of times per cylinder per minute. Can you imagine how much heat it releases? These explosions are relatively small, but in large numbers they produce intense heat. Consider an ambient temperature of 70 degrees. If the engine is "cold" at 70 degrees, how long after starting will the entire engine warm up to operating temperature? It only takes a few minutes at idle. How to get rid of excess heat generated during combustion? There are two types of cars used...

You may be driving down the road or sitting at a traffic light when you first notice your car's temperature gauge starting to rise. If you let it run long enough, you may notice steam coming out from under the hood, indicating that the engine is overheating. Problems with the cooling system can begin at any time and always occur at the most inopportune moment. If you feel like your car has a problem with its cooling system, knowing what to look for can…
How to check the cooling system
You can check the cooling system in various ways, and their choice depends on the reason for which it began to work worse. So, when white smoke appears from the exhaust, you need to look for an antifreeze leak, when the system is aired, you need to check the circulation of the coolant and its tightness. it is also worth inspecting the places of possible physical leakage of antifreeze, check the radiator cap and expansion tank, as well as the correct operation of the coolant sensor. Often, after checking the internal combustion engine cooling system, car owners flush it using special or improvised means. In some cases, replacing antifreeze or antifreeze helps, because over time these process fluids lose their properties, or they were initially incorrectly selected, for example, by a previous car owner. Signs of a breakdown in the cooling system There are a number of ...
Cooling fan constantly running
The situation when the cooling fan is constantly running can be caused by several reasons: failure of the coolant temperature sensor or its wiring, breakdown of the fan start relay, damage to the wires of the drive motor, “glitches” of the ICE electronic control unit (ECU) and some others. in order to understand how the cooling fan should work correctly, you need to know what temperature is programmed in the control unit to turn it on. Or look at the data on the fan switch located in the radiator. Usually it is within + 87 ... + 95 ° C. In the article, we will consider in detail all the main reasons why the internal combustion engine radiator cooling fan works not only when the coolant temperature reaches 100 degrees, but always with the ignition off. Reasons for turning on the fan Conditions for…
How to flush the engine cooling system
Usually, drivers are given the problem of flushing the internal combustion engine cooling radiator in the summer. It is in the heat that the internal combustion engine overheats most often due to insufficient cooling, due to contamination of the cooling radiator. The structure of the system is such that clogging and insufficient heat dissipation occurs not only due to external factors such as dirt, debris and everything else that the car encounters on our roads, but also due to internal factors - decomposition products of antifreeze, rust, scale inside the system. In order to flush the internal combustion engine cooling system, several methods can be used. Which one to choose depends on the degree of contamination. The main thing is to avoid banal errors of flushing the system. Cleaning with distilled water This method is suitable for new cars that do not have obvious ...
How you can remove an airlock from the cooling system
The presence of air in the cooling system is fraught with problems for both the internal combustion engine and other vehicle components. namely, overheating may occur or the stove will heat poorly. Therefore, it is useful for any motorist to know how to expel an air lock from the cooling system. This procedure is quite trivial, so even a beginner and inexperienced motorist will be able to do it. In view of their importance, we will describe three methods for removing air. But first, let's talk about how to understand that air traffic jams are taking place and about the reasons for their appearance. Symptoms of airing How to understand that an air lock has appeared in the cooling system? When this phenomenon occurs, several typical symptoms appear. Among them: Problems in the operation of the thermostat. More specifically, if after starting the internal combustion engine the cooling fan turns on ...
How to flush the engine cooling system?
The question of how to flush the internal combustion engine cooling system is of interest to car owners who are faced with the problems of cleaning the cooling jacket. There are both folk cleaning products (citric acid, whey, Coca-Cola and others), as well as modern technological formulations. Let's take a closer look at those and other options. Means for cleaning the cooling system from oil, rust and deposits How often to flush Before we move on to the nominal description of certain means, I would like to remind you how important it is to regularly flush the car's cooling system. The fact is that, depending on the coolant used, rust, oil deposits, antifreeze decomposition products, and scale accumulate on the walls of the tubes that make up the radiator. All this leads to difficulty in the circulation of coolant and ...
