Repair Sharan/Sharan Volkswagen>> System of greasing of the engine>> Oil replacement in the engine
Engine oil moves to all rubbing details of the engine at its work owing to what capacity losses on a friction between details decrease and wear of rubbing surfaces decreases. Besides, oil, passing between rubbing details of the engine, cools them and carries away wear products. At long operation of the engine oil gradually becomes soiled particles of metal, a deposit and a dust getting into a case, is diluted, therefore it is necessary to replace it.
In the operation manual it is possible to learn, when it is necessary to make replacement of engine oil. The basic rule is that oil should be changed not less than time in six months. Thus it is necessary to change also the oil filter, but is not more rare than once a year.
Replacement of engine oil carry out in the following order:
- warm up the engine;

Fig. 179. Installation of forward wheels of the car on special supports

- establish the car on a platform, the lift, a viewing ditch, or forward wheels on special supports (fig. 179) ;
- muffle the engine and tighten the parking brake;

At work under the car never leave the lifted car only on an automobile jack, make secure false support, etc.

At all do not rest a jack for car lifting against the case pallet, a transmission, an auxiliary frame or a back axis.

- remove a guard of protection of a case of the engine;
- substitute capacity for collecting the fulfilled oil under a drain stopper;

An arrangement of an oil radiator, the oil filter, maslomerny щупа, etc. elements on lateral face of the 2,0-liter engine: 1 — a cover of a maslonalivny mouth; 2 — a sealing ring; 3 — maslomerny щуп; 4 — a directing tube maslomerny щупа; 5 — an O-shaped sealing ring; 6 — the switch of pressure of oil on 25 kPas; 7 — the switch of pressure of oil on 180 kPas; 8 — a cap or the temperature switch; 9 — a bolt, 25 N · m; 10 — the basis of the oil filter; 11 — laying; 12 — an O-shaped sealing ring; 13 — an oil radiator; 14 — a nut, 25 N · m; 15 — the oil filter

- turn out a screw drain stopper in the pallet of a case and merge fulfilled oil in capacity;

Completely to merge old oil, it is necessary to wait some time. Having opened a cover of a jellied mouth 1 (fig. 180) or having pulled out maslomerny щуп 3, it is possible to accelerate process plum of old oil.

Hot engine oil can lead to burns. It is recommended to merge old oil while it still warm, but do not do it, when the engine hot.

To utilize old engine oil follows according to environmental protection rules.

- carefully clear a stopper of a drain opening and check a condition of a sealing ring;

- after old oil completely merged, wrap a stopper of a drain opening and tighten it the moment of 30 N · m;
- carry out the express analysis of the merged engine oil:
- if between big and index fingers, at a friction, feel existence of kernels or metal particles in the merged oil that most likely bearings are damaged;
- drops of water or yellowish color in oil indicate a leakage of laying of a head of the block of cylinders;
- too dark color of oil testifies that it was necessary to replace oil;
- fill in corresponding to requirements of the producer new engine oil to demanded level according to indications maslomerny щупа. To fill in oil follows slowly, periodically checking its level, however thus it is necessary to wait always some time that oil could flow down in an oil case;
- wrap a cover of a jellied mouth and start the engine for some minutes. It will distribute oil in the engine (the filter will be filled);
- stop the engine and wait some time that oil could flow down in an oil case;
- check shchupy oil level. Probably, it is necessary to add a little oil because of filling of the oil filter with it.
