The requirements for an antifreeze are enormously high, because on average, about 150 liters of coolant per minute are pumped through the cooling circuit of an average car. One third of the heat of combustion is released from the coolant to the atmosphere. The coolant passes over 100 different materials and must be compatible with all of them.
Tasks and requirements expected of modern antifreeze, such as:
- Antifreeze, i. e. reliable prevention of liquids freezing, even at extremely low temperatures
- Protection from soiling/deposits to keep the entire cooling circuit working properly in the long term
- Protection from overheating, for example if sufficient heat dissipation is no longer guaranteed due to soiling deposits
- Protection from aging and oxidation, so that the protective effect of the coolant remains intact through-out the entire duration of the respective service interval and
- Corrosion protection to reliably eliminate the risk of damage to any metallic materials in the cooling circuit, such as cast iron, cast aluminium, steel and brass.
Without proper coolant, the cooling system provides ideal conditions for corrosion thanks to its high temperatures and large volume of water. Deep rust spots/pitting can occur in the metal, potentially causing the coolant pump or the entire cooling system to fail. This can ultimately lead to extremely costly engine damage.
FUCHS recommends MAINTAIN FRICOFIN.
