febi outlines antifreeze range

To keep vehicles running smoothly, there are several different fluids used to grease components and provide lubrication. febi’s range of antifreeze is said to be matched to VMs’ specific requirements. PMF finds out more.

Internal combustion engines rely on coolant, which is pumped around the engine block and cylinder head, to prevent overheating and thermal distortion caused by the heat created in the combustion process. As the coolant is pumped through the engine casing, it absorbs heat, which is then circulated through a radiator to be cooled before returning. This cycle is repeated. Coolant is also circulated through the heater matrix and is used to increase the temperature within the vehicle interior as required. A perfectly functioning cooling system is a prerequisite for the optimum performance of an engine. The primary factor in ensuring this is using the correct coolant.

Coolant for water-cooled combustion engines prevents freezing at sub-zero temperatures. It helps to prevent corrosion within the cooling system, which, in turn, increases the service life of engine components. It also ensures that the moving parts within this system, such as the water pump, are lubricated.

Automotive coolants are a mixture of water and antifreeze concentrate. The recommended mix ratio is 1:1, which corresponds to a frost protection of -36°. The maximum possible protection can reach down to -52°, which is achieved by mixing at a ratio of 2:1 (concentrate:water). Pure antifreeze reduces the efficiency of cooling – compared to a 1:1 mixture – by about 50%. However, antifreeze concentrates also contribute to an increase in the boiling point, which, in summer, protects the engine against overheating. In a 1:1 mixture, the boiling point of the coolant is about 107°.

It is advisable that technicians regularly check the cooling system for the correct level and the correct mix ratio of cooling water and antifreeze.

Using high quality liquids promotes the longevity of moving parts such as water pumps, thermostats or heating valves. febi claims that its antifreeze is a state-of-the-art, long-term antifreeze concentrate based on mono ethylene glycol, with cutting-edge OAT (Organic Additive Technology).

The company also claims that its radiator coolant has been expertly matched to the specific requirements of VMs, whilst offering reliable protection against freezing, corrosion and cavitation damage.
