A typical situation: when opening the hood, the driver notices that bubbles have formed in the expansion tank. But the antifreeze was replaced quite recently. Yes, and filled
If bubbles appear in the antifreeze, be wary as these are the first signs of serious problems that could lead to the engine overheating.
First you need to understand where they come from. If the fluid change was performed correctly, there should be no air bubbles in the system. The cause must therefore be sought elsewhere. Note the antifreeze temperature. If the arrow on the instrument panel starts to climb up gradually, the new “slurry” is boiling. And it can cook due to the fact that something is frying it. This is done by gases entering the cooling system, for example via a perforated cylinder head gasket (cylinder head). But not everything is so clear here.
The danger of such a process is that it is rather slow. Usually, after a breakthrough, gases accumulate in the inner radiator of the heater. Thus, the circulation of antifreeze is disrupted and air bubbles are formed. The heater begins to malfunction, that is, the interior does not heat up, while the engine should not overheat. So the driver does not have to worry. It continues to drive, especially if the problem started in the summer, when the interior does not need to be heated.
Over time, it gets worse and small bubbles appear in the expansion tank. And they can appear in different ways. They can be seen when the engine has not yet warmed up, or vice versa, when the engine has reached operating temperature.
As long as the expansion tank cap works and can handle the pressure rise, nothing bad will happen. But there are more and more gases. As a result, the antifreeze will still boil and the engine will overheat.
You can prevent nuisance the old-fashioned way. We unscrew the cap from the expansion tank and put a ball on its neck. Then we start the engine. For starters, it should idle, and then you can press the right pedal. If the ball begins to fill with exhaust gases during operation, it means that the cylinder head gasket is broken.
There is another way. Car stores sell a special fluorescent compound, which is added to antifreeze before pouring it into the system. And after a short run, leaks are found using an ultraviolet lamp. Finally, the technicians get to work, because replacing the gasket is a time-consuming and expensive affair.
