What can cause damage to an engine's cooling system in winter?

The cooling system of a vehicle is crucial for maintaining the engine's temperature and preventing overheating. In winter, insufficient frost protection can lead to the coolant freezing, which can cause serious damage to the engine and cooling system.

Exchanging the coolant at least twice a year is also important because old coolant can lose its protective qualities. Regular maintenance ensures that the system operates efficiently.

According to German traffic regulations, proper maintenance and servicing of vehicles, including the cooling system, are critical for safety and performance. A failure to address these issues can have legal implications if they lead to accidents or breakdowns. It's essential to recognize that both insufficient frost protection and the need for regular coolant exchange are important considerations for winter vehicle maintenance.
