Few people know that overheating can occur due to a leaking plug in the expansion vessel. This happens after a visit to the service, where the masters changed the antifreeze. At the same time, the cork was quickly screwed and not along the thread. But the boiling point of the coolant in the cooling systems of modern machines is kept at a fairly high level (up to 120 degrees). If the system is leaking, there is no pressure. And if there is no pressure, the liquid will boil much earlier, causing the engine to overheat.
This can also happen due to a leaking radiator cap. But here is an important nuance. Overheating can be caused not only by a poorly screwed cork, but also by a completely new one that has been incorrectly selected. This happens if the opening pressure of the valve in the plug deviates from the standard. This indicator is usually stamped on the case, so you should pay close attention to it.
Problems with the thermostat will also lead to problems. If it sticks in the closed position, the antifreeze will not go into the radiator because the engine will boil quickly. Usually, the operation of the assembly is checked on a cold engine. After starting, we take the upper radiator hose. If it is cold, and the engine is already quite warm, the thermostat is stuck.
Interestingly, conventional motor oil can also lead to overheating. More precisely, it is a low level. This is especially true of modern engines, which, even new ones, are known for their “oil consumption”. If the driver forgot to look under the hood, drove on the highway for a long time, and then began to steer along the mountain serpentine, then this problem will arise. After all, oil not only lubricates, but also cools the engine. Therefore, the level must be constantly monitored. Especially if there is a mountainous area ahead and the car is fully loaded with all kinds of things that are needed, for example on vacation.
Finally, problems with the heat exchanger can lead to boiling. This is well known to GM car owners. The design of the “American” is such that oil can seep into antifreeze or vice versa. Thus, a liquid is formed in the cooling system, which slowly “fries” the engine.
