What may be the result of too little coolant in the engine?

When there is too little coolant in the engine, it can lead to serious issues. The first consequence is engine damage; without adequate coolant, the engine can overheat, which may cause significant internal harm, such as warping of engine components or even complete failure. This is critical because German traffic regulations prioritize vehicle safety and maintenance.

Additionally, overheating can lead to a breakdown, which poses a danger to road safety and can result in penalties if a vehicle is deemed unroadworthy. Although the increase of fuel consumption is a valid concern, it is not directly linked to the immediate and serious consequences of low coolant levels. Focusing on the most pressing issues related to engine performance and safety is essential under German regulations. Ensuring proper coolant levels is part of regular vehicle maintenance, which is mandated for safe operation on public roads.
