3.5. Replacement of engine oil and the oil filter

To greasing of details of the engine apply engine oil.
Besides greasing of pistons, bearings and other mobile details, it helps герметизировать cylinders from a high pressure, selects heat from hot sites, distributes it in the oil pallet and reduces corrosion.
After certain time engine oil becomes soiled owing to hit of a deposit, acids and extraneous impurity, its viscosity decreases, as a result oil loses ability to maintain a high pressure and temperature. Oil is necessary for changing every six months, this time interval has been changed for cars of release from the beginning of 1996 In magazine of procedural works on maintenance service the information on when it is necessary to change oil contains. Thus it is not necessary to replace the oil filter.
At plum of engine oil the car establish on reliable support. Is better to establish forward wheels of the car on basic platforms, as is shown in fig. 97.

To include a lay brake. In no event it is impossible to raise the car only one automobile jack if it is necessary to work under the car. Old oil is better to merge, when it warm. To put under a drain aperture low capacity and carefully to clear space round a stopper. To turn away a stopper.

The prevention
It is impossible to merge the fulfilled oil in the water drain and on the earth.

At oil plum carefully to clear a stopper of a drain aperture and to check up a condition of a sealing ring. After опорожнения the oil pallet again to screw a stopper of a final aperture and to tighten its moment 30 Нм.
The merged engine oil can be checked up. If to the touch at a friction between big and a forefinger it seems granular or parts of a silvery shade, possibly are looked through, bearings are damaged. Presence of water or a yellowish shade of oil are signs негерметичности consolidations of a head of the block of cylinders. Dark brown (or black) oil is unequivocally necessary for changing.
Fresh engine oil fill in in a bulk mouth through a funnel. Sometimes it appears to define difficultly exact quantity of filled in oil, therefore to fill in it follows slowly, constantly supervising level маслоизмерительным щупом and defining the moment of filling of the oil pallet according to the instruction. It is necessary to wait some time while oil will not flow down in the oil pallet.
After necessary level of oil will be reached, it is necessary to wrap a stopper of a bulk aperture and to start up the engine. Thus oil will be distributed on the engine (the filter is filled). Again to stop the engine and to wait, while oil will merge in the pallet.
Again to check up oil level маслоизмерительным щупом. Pure oil is sometimes imperceptible on measuring щупе, therefore it is necessary to spend some gaugings not to commit an error. If necessary to add engine oil to necessary level. It is necessary to fill in only the oil recommended by manufacturer.
