Check of tightness of system of cooling

Tightness of system of cooling and operation of the reduktsionny valve in a cover of a radiator can be checked by means of the special device. Such device can be got in the specialized centers.

 PERFORMANCE ORDER

    To uncover a radiator and to check a branch pipe and a cover on existence of a rust and lime deposits, if necessary to remove them.

To uncover only if the radiator is cooled at least to temperature of hands, differently there is a danger to be scalded by hot cooling liquid. For safety to lay round a branch pipe a rag.


    To screw instead of a radiator cover a connecting element of the verifying device.
    To create in system pressure pumping. Pressure should be about 1,1 Bar. The created pressure should remain to constants of 2 minutes. If pressure falls, to find not tight places in cooling system. To reduce pressure and slowly to unscrew a connecting element.

Check of the reduktsionny valve

 PERFORMANCE ORDER

    The Reduktsionny valve is in a radiator cover. Into its task enters to open cooling system at emergence of superfluous pressure and to return flowing liquid in a broad tank.
    For check to screw a radiator cover on the verifying device.
    To create pressure. To load the valve with pressure 0,7 - 1,0 Bar. In 10 seconds to check, whether pressure decreased. If pressure decreased, it is necessary to replace a cover.

Check of the valve of the lowered pressure

 PERFORMANCE ORDER

    The valve of the lowered pressure also is in a radiator cover. After cooling of cooling liquid in system he allows liquid to follow from a tank.
    To take out the valve of the lowered pressure, and to check, whether completely it is closed at an otpuskaniye. If it is closed not completely or laying is damaged, it is necessary to replace a cover.
    To screw a cover on a radiator, in case of damage to replace rubber laying.
