Repair Sharan/Sharan Volkswagen>> Cooling system>> Cooling liquid>> Replacement of cooling liquid
Replacement of cooling liquid carry out in the following order:
- put a control lever of heating of salon on the dashboard in the situation "Heiss" (hot);
- unscrew a cover of a broad tank. If the engine hot, it is necessary to wait some time before opening a cover of a broad tank;
- put under the engine capacity for liquid plum.
Engine of 2,0 l

Fig. 182. Part of details of system of cooling of the 2,0-liter engine: 1 — a radiator; 2 — a radiator casing; 3 — the top hose of cooling liquid; 4 — a bolt, 10 N · m; 5 — a basic bar; 6 — the bottom hose of cooling liquid; 7 — an adjusting ring of the fan; 8 — the fan of system of cooling; 9 — a shtekerny block of the temperature switch, black color; 10 — the temperature switch, 35 N · m




Fig. 183. Plums of cooling liquid from system of cooling of the 2,0-liter engine: 1 — a hose of cooling liquid; 2 — a connecting element; 3 — a collar; 4 — a thermostat flange




Disconnect the bottom hose 6 (see fig. 182 ) cooling liquid from a radiator or unscrew the socket of a branch pipe of cooling liquid (fig. 183) and merge cooling liquid.

Note
If cooling liquid in a good condition, i.e. it recently filled in, it can be used repeatedly.

Note
Hoses in places of their connections fasten by means of clips similar to collars which are recommended to be removed by means of special nippers at number 798-5.

VR6 engine

Fig. 181. Part of details of system of cooling of the VR6 engine: 1 — a rubber support; 2 — the top hose of a radiator from the thermostat case; 3 — a radiator; 4 — a radiator casing; 5 — a bolt, 10 N · m; 6 — a rubber washer; 7 — a basic foot; 8 — a shtekerny block of the right fan (black); 9 — a collar for a shtekerny block of the right fan; 10 — the right fan; 11 — a fan casing; 12 — an inlet hose; 13 — a hose under pressure; 14 — the air pump of a high pressure; 15 — a collar for a hose; 16 — a bolt, 25 N · m; 17 — the left fan; 18 — a shtekerny block for the left fan (black); 19 — the bottom hose of a radiator (from the thermostat); 20 — a shtekerny block of the temperature switch (black); 21 — the temperature switch for the fan





Turn out a stopper of a drain opening or disconnect from a radiator the bottom hose 19 (see fig. 181 ) cooling liquid and merge cooling liquid in in advance prepared capacity;
- on the 2,0-liter engine attach to a radiator the bottom hose of cooling liquid or tighten a branch pipe of cooling liquid with new laying;
- on the VR6 engine wrap a stopper of a drain opening with a new sealing washer and tighten it the moment of 10 N · m. If the bottom hose of cooling liquid was disconnected from a radiator, again establish it;

Fig. 184. Broad tank of system of cooling. Level of cooling liquid in a broad tank should be between labels "Move" and «Мin» (it is shown by an arrow)





- fill in cooling liquid in a broad tank to a label "Move" (fig. 184) and wrap a cover of a broad tank;
- start the engine and let's to it work, the fan (the 2,0-liter engine) or fans (VR6 engine) will not turn on yet;
- muffle the engine and let's to it cool down;

Prevention
The electrofan (or electrofans) can independently turn on, even several times, and at the switched-off ignition because of heating in a motor compartment of the car.

- check level of cooling liquid in a broad tank. It should be established between labels "Move" and «Мin» on a broad tank. If level is lower, add cooling liquid. If the engine hot, level of cooling liquid can be a little higher than a label "Move".

Note
In the absence of special cooling liquid application pure "soft" is allowed (for example, rain) waters, however its application raises freezing temperature, strengthens corrosion and scaling.

Prevention
Availability of water in a broad tank at negative temperatures is not allowed.
