b47c026d b47c026d Check of tightness of system of cooling


Squeezing and bending, check hoses with cooling liquid on lack of porous places, replace become rigid hoses.

Hoses cannot be put on too shortly connecting branch pipes.

Check rigid landing of collars for rubber hoses, if necessary replace collars.

Check consolidation of a locking cover of a radiator or a compensatory tank on absence of damages.


Too low level of cooling liquid can be caused by the also incorrectly twirled locking cover of a radiator (there is no tightness).

Accurate leakage of cooling liquid and / or availability of oil in cooling liquid, and also at the hot engine indicate white clouds of exhaust gases the damaged laying of a head of the block of cylinders.


It is sometimes difficult to find a leak place. In this case we recommend to apply test by pressure in a repair truck (the special device is required). Thus it is also possible to check a safety valve of a locking cover of a radiator.
