NL Why you should keep an eye on the cooling water
Imagine you are driving relaxed on the highway, the engine is purring contentedly and everything seems to be in perfect order. Suddenly your eyes fall on the temperature display - and it climbs rapidly into the red zone. This is a worrying sign that you should not ignore. At such moments, this often means one thing: your engine is losing cooling water.
Without sufficient coolant, the engine can no longer be cooled sufficiently, which inevitably leads to overheating. This puts the cooling system under enormous pressure and the rising heat can have serious consequences. Overheating is no small problem - it can lead to serious damage to the engine, in the worst case even to a total loss. Quick action is crucial here, because every minute in the red zone brings the engine closer to an irreparable state.
What are the typical triggers?
The cooling water is "vital" for the smooth operation of our vehicles. It ensures that the engine does not overheat by dissipating excess heat. However, if your car Cooling water lossthis may indicate various problems in the cooling system that you should definitely rectify in order to avoid serious damage to the engine.
- Cracked or porous radiator hosesOver time, the hoses of the cooling system can become brittle and develop small cracks through which cooling water slowly escapes.
- Faulty water pumpThe water pump circulates the coolant in the system. If it no longer works properly, this can lead to a loss of coolant.
- Cracks in the expansion tankA damaged expansion tank or a defective cap can cause cooling water to escape.
- Defective cylinder head gasketA common and serious reason for the loss of cooling water is a leaking cylinder head gasket, through which the cooling water enters the combustion chamber and is burnt there.

Cooling water loss without leakage - a creeping problem
Ein Kühlwasserverlust ohne sichtbaren Austritt gehört zu den tückischsten Problemen, denen Autofahrer im Alltag begegnen. Oft bleibt der Verlust so lange unbemerkt, bis der Schaden fortgeschritten ist. Es gibt keine offensichtlichen Lecks und erst wenn die Anzeige für den Kühlmittelstand aufleuchtet oder der Motor überhitzt, wird das Problem deutlich. Eine häufige Ursache dafür ist eine defekte Zylinderkopfdichtung, die Kühlwasser in den Brennraum gelangen lässt, wo es verdampft oder verbrannt wird. Dieser schleichende Prozess führt dazu, dass der Motor nicht mehr ausreichend gekühlt wird und schnell überhitzt. Wenn die Temperaturanzeige gefährlich ansteigt, ist schnelles Handeln gefragt: Halte sofort an und stelle den Motor ab, um schwerwiegende Schäden bis hin zum Totalschaden zu verhindern.
Signs of a defective cylinder head gasket
One Defective cylinder head gasket is undoubtedly one of the most serious problems with a combustion engine. If you notice any of the following signs, you should act immediately and have your vehicle checked in a workshop to avoid expensive engine damage.
Weißer Rauch aus dem Auspuff: Beim Starten des Motors oder beim Gasgeben entweicht plötzlich dichter, weißer Rauch aus dem Auspuff. Was auf den ersten Blick harmlos wirkt, hat eine ernsthafte Ursache – Kühlwasser hat seinen Weg in den Brennraum gefunden und wird dort zusammen mit dem Kraftstoff verbrannt. Dieses ungewöhnliche Schauspiel aus der Auspuffanlage ist ein klarer Hinweis, dass im Motor etwas ganz und gar nicht stimmt.
Bubble formation in the cooling water: If you notice bubbles or foam when opening the coolant expansion tank, this indicates combustion gases in the cooling system. These can enter the system through a leaking cylinder head gasket.
Difficulties starting the engine: If the engine is difficult to start or runs unevenly, this could also indicate a leaking cylinder head gasket. Cooling water in the combustion chamber impairs compression and ensures that the engine does not run smoothly.
Overpressure in the cooling system: Eine defekte Zylinderkopfdichtung kann auch dazu führen, dass Verbrennungsdruck in das Kühlsystem gelangt. Dies führt zu einem erhöhten Druck, der die Kühlwasserschläuche aufbläht und das Kühlsystem beschädigen kann.
How to rectify the loss of cooling water
The good news is that coolant loss does not always have to be a case for the workshop!
If there is a lack of coolant, you should top it up regularly to prevent the engine from overheating. It is important to use the right mixture of water and antifreeze, as this combination provides optimum protection for the engine.
If the coolant is lost without escaping, i.e. if coolant keeps disappearing to the outside without any recognizable leaks, this indicates a leaking cylinder head gasket. As long as the engine starts and 60 minutes in standby mode runs without overheating, you can solve the problem Simple, fast and cost-effective with Steel Seal® fix. Thanks to its unique, fiber-free formula, Steel Seal® works quickly and effectively. holds permanently.
If the engine can no longer be started and made to run at all due to a water hammer (too much cooling water in the combustion chamber can no longer be compressed), the engine must be replaced. Replacing the cylinder head gasket unavoidable and that should be a motor Specialized car mechanic take over.
Our tips for preventing cooling water loss
To ensure that the cooling system works perfectly for a long time, there are a few important to-do's that you should carry out regularly.
First of all, regular maintenance is essential. Have the cooling system checked at every inspection to detect potential problems at an early stage and prevent major damage. Another important point is to change the coolant regularly. Over time, old coolant loses its protective effect, which can cause corrosion in the system. You should therefore replace the coolant every two to three years. You should also look out for warning signals at an early stage: If your vehicle overheats or unusual noises are heard from the engine compartment, do not hesitate to have the cooling system checked immediately.
