Regular replacement of the coolant protects against frost, corrosion and overheating
Schwäbisch Hall, October 2010. Thermal management expert Behr Hella Service recommends the regular replacement of radiator antifreeze as it not only protects against frost, but also against corrosion and overheating. Coolants are subject to a certain degree of wear, which is why vehicle manufacturers stipulate that they must be replaced at specific intervals. The coolant should be replaced every three years unless "long life" coolant is used. The ratio of water to antifreeze should be in the range of 60:40 to 50:50, which provides frost protection from -25°C to -40°C. The freezing point does not sink any lower at a ratio of 40:60 or more. Undiluted antifreeze freezes at -13°C already and also no longer discharges sufficient heat from the engine at temperatures above 0°C. Both Behr Hella Service and Hella online provide further tips and detailed information about this and other topics in the Technical Information section in the Hella Aftermarket Club.
