GEBA COOLANT Triple protection against corrosion, superheating and frost.

ADDITIVES

As the name suggests, additives are additive substances which produce particular (special) properties.
In GEBA coolants they give coolant additional properties, such as protection against corrosion, elimination of foam forming, and many more. Also additives give GEBA coolants a special colour so that they can be easily distinguished by customers.

HARD WATER

Water hardness is a word from chemistry which refers to the concentration of ions, anions and metals melt in water. Calcium and magnesium ions, for example, are here numbered among “hardness makers”.
In electrical appliances, hard water may cause, among other things, calcification. When the radiator
protection is changed, it‘s suggested to use water not harder than 3,566 mmol/l for the diluition of
GEBA coolant.

If the available tap water is not suitable as for its hardness or cleanliness, GEBA coolants may be diluted with no problem, using distilled or demineralized water.

INHIBITORS

The name “inhibitor” refers to the latin verb which means to stop or to prevent. In fact these substances can prevent or slow down chemical reactions. For GEBA coolants the so called corrosion inhibitors are mostly important. These combine with the metals of the cooling system and form a very thin but highly protective layer on it. In this way the various components of the coolant are protected from corrosion.

CAVITATION

Cavitation cant‘be avoided in the complex cooling system and it always occurs during the functioning. It‘s caused by different pressure conditions in the cooling system during the functioning: when pressure decreases, are found some steam bubbles which deflete as soon as pressure increases again. This may cause deep impacts on the metallic surface. Cavitation may occur in the coolant channels, in the water pump, in the cylinders block, in the cylinders jacket or in the cylinder head. Without proper additives corrosion and a strong wear may fast occur.

CORROSION

If the radiator has no protection, the cooling system of a vehicle has ideal conditions for corrosion.
That‘s due to high temperatures and water used for cooling .

In a few words, corrosion means that substances interact with the surrounding environment and are so transformed. In a cooling system it means that, for exampe, oxygen is formed, which reacts with the different materials in the cooler. This may cause a well known form of corrosion: rust. So metal loses colour and becomes unstable and full of holes.

COOLANT

To dispel heat generated from fuel combustion in engines, a cooling system is required in motor cars.It usually consists of a mix of water and a concentratred agent of radiator protection. Unfortunately the wrong term “cooling water” is also largely used.

Water is excellent as a coolant thanks to its properties. It can either absorb or transport heath quite well.However, water without a protection agent of the radiator shouldn‘t be used as a coolant, because it may damage the vehicle ! At low temperatures water expands up to 10% and so it may break the radiator and the motor unit. In this case there is a high risk of damages to the engine. At high temperatures, water as coolant, wouldn‘t cool the engine enough, with a risk of superheating. Besides the corrosion risk is very high, because high temperatures in the cooling system, together with water, offer ideal conditions for rust. High quality coolants, such as GEBA coolants , assure to cool down the engine in a level way either in heat or ice conditions and protect the cooling system materials from corrosion thanks to an extremely resistant protective coat. Every 3 or 4 years the protection of the vehicle radiator should be changed.

GEBA COOLANT – TIPS FOR USE

  • A wrong filling of coolant causes damages to the cooling system!
  • Always replace coolant totally during the repairs, rinse and clean the cooling system in advance!
  • For 6 years older vehicles it‘s recommended to renew the radiator protection every  3 or 4 years!
  • The radiator protection is a year long protection!
  • Never mix coolants of different types!
  • Use clean water!
  • Always follow the instructions of vehicle manufacturer!
  • The right ratio of blending must be always respected!

GEBA COOLANT –
QUESTIONS AND ANSWERS

Corrosive molecules are generated from the breakdown of the ethylene glycol contained in the engine coolant and the gradual breakdown of the additives and inhibitors it contains. The degradation is caused by the high thermal loads in the engine‘s cooling circuit. The engine coolant must be changed regularly after three to four years.
