Engine cooling system

Antifreeze - a means of protection against freezing

Do not suppose antifreeze hit on open sites of a body and the painted surfaces of the vehicle. Casual splashes immediately wash off with plenty of water. Remember that antifreeze is highly toxic liquid and its hit in an organism even in small amounts is fraught with the most serious consequences, including death. Never leave antifreeze stored in leaky closed container, immediately collect spilled on the floor coolant. Remember that the sweetish smell of antifreeze can draw the attention of children and pets. About disposal of used coolant, consult with the local authorities - in many parts of the world special points on any reception of working off. In no case do not drain the old coolant down the drain and to the ground!

Recently developed non-toxic antifreeze grade, however, they must be disposed of in an organized manner.

Coolant

In order to prevent clogging of the radiator corrosion products of aluminum components in the mixture to fill the radiator is recommended that a special antifreeze / corrosion inhibitor (KFM) with distilled water. Mercedes-Benz company approved for KFM ?�TYPE 30".

The cooling system is filled year-round with a mixture of water, antifreeze and anti-corrosion agents. This prevents rust and corrosion, deposition of salts and, moreover, raises the boiling point of the coolant. In the cooling system due to expansion upon heating fluid is pressurized, which also leads to an increase in the boiling point of the coolant. Pressure limited located in the lid of the expansion tank valve, which opens at a pressure of 1.4 ÷ 1.6 atm. Additional efficiency of the cooling system is achieved by increasing the boiling point of the coolant. The excess of the boiling point leads to the formation of vapor lock, disrupts the normal circulation of the liquid in the cooling path.

Taking this into account, for refilling the cooling system should be at any time of year only use a mixture of the desired composition (see. Specifications).
