ATTENTION
When opening the broad tank can come out hot steam or hot cooling liquid. Wrap up a cover rags and carefully open a tank.

NOTE
At the warm engine the cooling system is under pressure. If necessary before repair work it is necessary to dump pressure.

Record all connections of hoses collars which correspond to a serial complete set.
For Ustanovkaa of spring collars it is recommended use pincers for hose collars or pincers for spring collars.
Laying and sealing rings needs to be replaced.
The arrows put on the ends of tubes and hoses of the cooling system have to is against each other.
