Check of tightness of the cooling system

Squeezing and bending, check hoses with cooling liquid for lack of porous places, replace the hoses which became rigid.

Hoses cannot be put on too shortly connecting branch pipes.

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

Check consolidation of a locking cover of a radiator or a compensation tank for absence of damage.


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

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


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