Check of system of cooling under pressure Tightness of system and safety valve work in a radiator cover can be checked up by means of the special tool, for example, HAZET 4800/9.
1 Check up level of a cooling liquid. 2 Check up, whether dry all joinings of hoses. If necessary wipe them.
4 the Created pressure can fall during 2 mines no more, than to 0.1 bar. If pressure falls further, reveal a leak place in system. At a raising of pressure the liquid follows through a leak place. Condense a leak place. 5 If pressure falls without liquid loss, the leak place can be in the engine, for example, the defective sealing lining of a head of cylinders or a crack in the case can be such place. 6 If pressure keeps, though in the course of car movement loss of a cooling liquid takes place, start the engine and allow to it to work on single turns. The manual pump create pressure nearby 1 bar and check up visually a radiator. Localise негерметичность and condense. 7 Stop the engine. Slowly turn away a connecting element, having removed pressure in cooling system. Check of the valve of a stopper
9 Create the manual pump of the tool pressure. The stopper should be tight. The safety valve in a stopper should open only at pressure 1.0 bar (Models 320d: 1.4 bar). Otherwise replace a stopper. 10 Create in a stopper vacuum. At vacuum 0.1 bar the vacuum valve in a radiator stopper should open. 11 In the presence of damages of a rubber ring to a stopper replace it. Screw a stopper. |
