Mercedes S-Class W-140

1. Carefully check heater hoses, and also heater hoses which have smaller diameter. Check cooling system hoses on all length, compensation of any bursting, swelled up or worn-out hose generating. Cracks need to be found if it is easier to squeeze a hand hose. If collars which hold hoses on cooling system components address. Hoses can or pierce these collars cut that will lead to a vytecheniye of the cooled liquid.
2. Be convinced from reliability of strengthening of all schlangowych of associations. Vytecheniye is shown to the cooled liquid in the form of white or rusty color of deposits in the field of Kapselung violation usually. If by your car collars like a wire are used, then it has to replace sense with collars like screws.
3. By means of compressed air or a soft brush you clean a forward part of the heater (and also the air conditioner condenser there where is available it). Remove all insects, leaves and other minor objects which got to edge of the heater, - you are very careful not to damage edge about them not to cut fingers.
4. If the level of the cooled liquid constantly falls, and you did not find a vytecheniye, it is necessary to make it is necessary check of the cooling system of pressure in the conditions of 100 Mercedes Benz.

1. Prior to the beginning of a winter season by all means owe concentration of means against a cold injury in the cooled liquid, especially check if in system clear water in the enterprise it was filled in, - you use areometrom with award of the academic degree on frost resistance.
2. Heat the motor a little in such a way that the top hose of the heater was heated. At measurement of concentration of means against a cold injury temperature of liquid has to form along with these +20 °C.
3. Carefully prevent a stopper of the expanding container.

1. For removal of the cooled liquid you place a peel under the heater and you prevent a stopper of a waste opening of the heater.
2. It is impossible to delete completely old liquid from system it (without full discussion of the motor) therefore all volumes which are specified in specifications are caused. In practice you can fill in in system along with 2/3 ordered liquid payment.
3. After gas station of system of fresh means against a cold injury you place on the label expanding a container with the indication of concentration, means brand against a cold injury and date of compensation. Any following addition of system (to systematic compensation) has to be carried out only by the specified liquid.

1. If you think that there are air traffic jams in system, try to squeeze in turn, first of all, all available hoses of ochladitelnogo of a path. You define them at once, the hose liquid or air is stuffed. As a rule, all air traffic jams vanish after the first (after compensation of liquid) start of the motor.
2. At the working heated motor will accept the heater and its fan. Warm air has to work in salon in enough. If temperature of the served air low, the reason, perhaps, an air stopper.
3. Consequences of emergence of air traffic jams in system it can be very serious (not simply immersion of overall performance of the heater). The big stopper can stop the address of liquid within the motor. To be convinced of lack of traffic jams within the motor, concern the top hose of the heater at the working motor - it has to be hot. If the hose cold testifies, it about existence of an air stopper in the motor or to the wrong thermostat.
4. If you could not escape air traffic jams, allow to the motor completely to cool down, accept a cover of the expanding container, try to squeeze system hoses. Even if it would not help, pull together everything the cooled liquid in a pure container and again you correct system of the same liquid, to recommendations, вышеупомянуто the following.
