Next to the electrical system, the cooling system in the car is most susceptible to problems.
Anti-freeze agents with their corrosion inhibitors reliably protect all metals found in the cooling system against corrosion and deposits. This increases the functional reliability and the service life of the cooling system components such as the radiator, heat-exchanger, water pump, cylinder head and engine.
Aluminium engines place higher requirements on corrosion protection. All automotive manufacturers research continually and intensively into further development, in co-operation with the manufacturers of anti-freeze agents. The approval conditions of the automotive manufacturers for common anti-freeze agents must also be observed.
