1.5.15.3. Addition of cooling liquid

GENERAL INFORMATION

Muffle the engine and let's to it cool down.


Prevention

Reduce risk of an oshparivaniye hot cooling liquid, following conforming to the rules:

 – if it is necessary for you to uncover a broad tank of cooling liquid, wait, while the engine will cool down;
 – the system of cooling is under pressure; protect the face, hands and forearms, having covered a cover with a big piece of a thick matter not to be scalded by the leaving steam or liquid;
 – accurately and slowly turn a cover on one turn to let off steam before completely uncovering.

Always add antifreeze and water in the ratio, designated on capacity the producer of antifreeze.

The increase in the content of antifreeze in cooling liquid more than for 60 % not only is not economical, but also negatively affects engine cooling.

It is necessary to use only qualitative antifreeze which is containing этиленгликоль and not containing phosphatic connections.

Use of antifreeze, excellent from recommended by Aуди firm, can cause corrosion of system of cooling that will lead to an overheat and engine damage.

A small amount of the antifreeze containing этиленгликоль and phosphatic connections, can be used only for small refueling of system of cooling if you have no antifreeze of demanded brand.

Cold antifreeze and cold water it is necessary to fill in only when the engine also cold.


After addition of cooling liquid, let's to the engine work in an idling mode within several seconds.

Once again check level of cooling liquid. Add cooling liquid if it is necessary.


Prevention

Do not overflow cooling system.

The excessive amount of cooling liquid will be merged via the reduktsionny valve in a broad tank when the engine will get warm.

Reliably twirl a cover of a broad tank after filling of cooling liquid.
