2.8.2. Replacement of cooling liquid of the engine

Stop the engine and let's it cool down.

Even in this case at removal of a cover it is necessary to show care. Wrap up thick fabric around a cover and slowly turn it counterclockwise to the first limiter. Depart from a radiator for the period of dumping of pressure.

When you are sure that pressure decreased, press on a cover, having wrapped up it fabric, turn and remove it.

ATTENTION Cooling liquid of the engine damages a paint and varnish covering. If cooling liquid of the engine got on the painted surface, immediately wash away it.

Fig. 2.305. Broad tank of the cooling system

Uncover a broad tank of the cooling system (fig. 2.305).

Remove the lower cover.

Fig. 2.306. Drain stopper of a radiator of the cooling system

Turn off a drain stopper of a radiator and merge cooling liquid of the engine in a container (fig. 2.306).

Wash out the cooling system water under pressure, before decolouration of water at the exit.

Let's water flow down completely from system.

Tighten a drain stopper of a radiator.

Inhaling moment: 1,2–1,5 N · m.

Choose concentration of antifreeze according to the provided table 2.34.

Add cooling liquid in a broad tank of the cooling system to a maximum tag.

Establish a cooling system cover.

ATTENTION If the arrow of the index of temperature of cooling liquid came into a red zone, stop the engine and wait until it cools down to prevent an overheat. After that reveal a faulty element and repair or replace it.

Start the engine and leave it to idle until the arrow of the index of temperature is is in the center of a scale, and the frequency of rotation of the engine will be less than 1500 ^min.-1.

After the engine gets warm, execute the following, controlling temperature of cooling liquid of the engine the thermometer.

Let's the engine work for 2500 ^min.-1 within 5 min.

Let's the engine work for 3000 ^min.-1 during 5 with, and then leave it to idle.

Again let's work to the engine for 3000 ^min.-1 during 5 about two times.

Stop the engine and let's it cool down.

Check the level of cooling liquid.

If level low, add cooling liquid in a broad tank of the cooling system to a maximum tag.

Be convinced of lack of leak of cooling liquid.

In the presence of leak, define a defective part and repair or replace it.
