Replacement of cooling liquid - general comments

See also Section Check of Functioning of the Cooling System and Frost Resistance of Cooling Liquid, replacement of liquid in the Head Routine maintenance

Do not allow hit of antifreeze on open parts of the body and the painted surfaces of the car.

Immediately wash away casual splashes a plentiful amount of water.

Remember that antifreeze is extremely toxic liquid and its hit in an organism even in small amounts is fraught with the most serious consequences, up to a lethal outcome.

Never leave antifreeze stored in leaky closed container, immediately collect the cooling liquid spilled on a floor.

Remember that the sweetish smell of antifreeze can draw to itself attention of children and animals.

About ways utilization of the fulfilled cooling liquid consult with local authorities, - in many regions of the world special points on different reception of working off are equipped.

Do not merge old cooling liquid in the sewerage and on the earth at all!

The merged cooling liquid should not be applied again. Cooling liquid is poisonous and should not merge with household waste.


The sensor switch of level of cooling liquid is located on day of a broad tank in the right part of a motive compartment

Cooling liquid has to be replaced at repair of the cooling system at which liquid merges. In case at repair the head of cylinders, the block of cylinders, sealing laying of a head of cylinders, a radiator, the heat exchanger or the engine are replaced, then cooling liquid has to be replaced with new. In the course of circulation anticorrosive additives are besieged on new details from light metal and by that form a durable anticorrosive layer. In the used cooling liquid of anticorrosive additive, as a rule, it is already not enough to form a sufficient protective layer on new details.
The description of procedures of replacement of liquid is provided in the Head Routine maintenance.
