1.5.15.1. Check of level of cooling liquid

GENERAL INFORMATION

Level of cooling liquid is necessary for checking from time to time, and also to do it before distant trips.


Prevention

Not to burn, never open a cowl if you hear or see that steam or cooling liquid leave an impellent compartment. Wait, it will not be audible yet or it is visible pair or cooling liquid and only after that carefully open a cowl.


As the broad tank of system of cooling is executed from transparent plastic, there is no need to open a cover for check of level of cooling liquid.

At the cold engine, level of cooling liquid in a transparent broad tank should be up to standard of MIN mark (it is specified by an arrow).

At the warmed-up engine, level of cooling liquid should rise a little above this mark.


On a broad tank the electronic device of check of level of cooling liquid is also established.

If level of cooling liquid falls below MIN mark, the alarm bulb of system of cooling will light up.

Reduction of level of cooling liquid

Reduction of level of cooling liquid can testify to leak existence in cooling system. In this case, the system of cooling should be checked. It is insufficiently simple to add cooling liquid.

In tight system leakage of liquid can occur only if the temperature of liquid rose above a boiling point as a result of an overheat.
