KÜHLERSCHUTZ D-40 Super provides excellent protection against frost, rust and overheating for all modern engines, especially heavy-duty aluminum engines. It effectively prevents corrosion and deposits in the cooling system with its important components such as cooling channels in the cylinder head, engine block, radiator and water pump. As the special application benefits of KÜHLERSCHUTZ D-40 Super are only achieved when KÜHLERSCHUTZ D-40 Super is used alone, mixing it with other coolants is not recommended. KÜHLERSCHUTZ D-40 Super should be mixed with water (clean, not too hard water should be used to prepare the coolant) and used in a concentration of 35 to 55% by volume before filling into the cooling circuit.
