THE GENERAL DATA

The cooling system a round code is filled by a mix consisting of water, antifreeze and anticorrosive means. This mix prevents occurrence of the damages connected with freezing and коррозийным by influence, formation of limy adjournment and, besides, slightly raises temperature of boiling of a cooling liquid. Thanks to a carving cover on a compensatory tank, at the heated-up engine in a cooling contour superfluous pressure nearby 1,4 bar which too promotes rise in temperature of boiling of a cooling liquid is created. The raised temperature of boiling of a cooling liquid is required for normal functioning of system of cooling of the engine. At too low temperature of boiling of a liquid it can lead thermal подпору because of what circulation of a cooling liquid is broken and engine cooling decreases. Therefore the system of cooling within a year necessarily should be is filled by a mix of cooling concentrates.
The prevention

Apply only cooling concentrates resolved for car Mercedes.


As after a while the anticorrosive component in a cooling liquid loses the effective influence it is necessary to replace cooling liquid every 3 year.
The prevention

If the antifreeze maintenance in a cooling liquid exceeds 55 % (corresponds to protection to–45 C) protection against a frost decreases and heat removal by cooling system worsens.
