The coolant discharges the heat generated by the combustion engine to the radiator, thereby ensuring that the motor runs at its ideal operating temperature. The coolant also protects the motor against internal corrosion and lubricates vital components like the water pump. The coolant protects the engine block against freezing in the winter.
It is crucially important for the coolant to contain sufficient antifreeze to protect the engine and the radiator even in extreme winter temperatures. The inadequate cooling caused by insufficient antifreeze can cause grave damage such as cracks in the radiator and/or the engine block or damage.
- Ensure that you check the level and the coolant freezing point before the winter sets in
- Replace the coolant after 5000 hours of operation – after excessively long use, the coolant acquires aggressive properties that can cause corrosion and can corrode internal water hoses.
