3.6. Replacement of impellent oil and oil filter

Impellent oil is among cancerogenic substances and at long contact can cause a skin cancer — use protective gloves!
Utilization of the merged impellent oil should be made according to requirements of the local legislation for environmental protection!

Oil replacement

The tool kit, necessary for replacement of impellent oil and the oil filter

1 — the Drain capacity should be superficial and rather wide to minimize probability of a prolivaniye of oil on the earth
2 — Rubber gloves will help to protect hands from burns at inevitable hit of oil on them during a reversing of a drain stopper of the pallet of a case
3 — the Collar — sometimes the drain stopper appears tightened rather hardly that demands considerable effort at its reversing

4 — the Replaceable face head is applied together with a collar or the equipped ratchet a drive at a reversing of a drain stopper, should correspond to the last on the size
5 — the Tape key allows to turn out the polnopotochny oil filter in the conditions of the access limited to it
6 — the Special cap key is put on an end face of the filter and can then rotate by means of a collar or a ratchet drive, should answer the filter case on the size

Regular and rather frequent performance of replacement of impellent oil is one of the main procedures of preventive maintenance of the car, lying within qualification of the average amateur mechanic. Eventually impellent oil is subject to aging that is shown in its gradual razzhizheniye and the pollution, conducting to premature wear of internal components of the engine. In spite of the fact that separate sources recommend to make replacement of the oil filter only at every second change of impellent oil, originators of the real Management consider that in view of relative insignificance of cost of a replaceable component and importance of influence of its condition on serviceability of functioning engine / efficiency of its return, it is meaningful to change the filter each time at oil replacement.

The scheme of an institution of props for car fixing in the lifted situation

Removal of impellent oil



  1. Make sure available near at hand all materials and the tools necessary for performance of replacement of oil and the oil filter (see the illustration Tool kit, necessary for replacement of impellent oil and the oil filter). Prepare also enough of rags and old newspapers for collecting traces of the spilled oil.
  2. For the purpose of providing a free access to the pallet of a case and to the oil filter tire out the car on a platform / a viewing hole, or поддомкратьте it and establish on props (see an illustration the Scheme of an institution of props for car fixing in the lifted situation).

At all do not carry out any works under the car which has been propped up only under a bumper or withheld in lifted situation only by a jack!

  1. Be appropriated for the car and familiarize with an arrangement of a drain stopper of the pallet of a case and the oil filter. Remember that the power unit and components of system of production of the fulfilled gases during the whole time of performance of procedure will remain rather hot — think over the scheme of safe manipulations with hands to avoid casual contact to the warmed-up surfaces.
  2. Make sure of horizontal position of position of the car on props / lift. Warm up the engine to normal working temperature — hot oil possesses bigger fluidity and better washes away шлам and a precipitation. Use the compelled idle time to spread out in a convenient order all necessary tools and materials. Muffle the engine and uncover a jellied mouth of impellent oil (see an illustration Removal of impellent oil).
  3. Make sure of reliability of fixing of the car in the lifted situation.
  4. Being careful, be appropriated for the car and establish drain capacity under the case pallet, with that calculation that during the first moment the stream will follow through an opening with a decent pressure. Trying not to touch the warmed-up surfaces of the power unit and components of system of release, turn out a drain stopper from the lower part of the pallet of a case (see an illustration Removal of impellent oil) — depending on oil temperature, at a final stage of a reversing of a stopper it is possible to use rubber gloves, or to refuse them.
  5. Allow oil to flow down freely in capacity, as appropriate correcting situation of the last in process of weakening of a pressure of a stream. Check the merged oil on presence at it metal sawdust.
  6. After oil will stop to follow from an engine case, carefully wipe a drain stopper pure rags — to it can подлипнуть small metal sawdust which will immediately lead to pollution of fresh oil.
  7. Wipe a pallet surface round a drain opening, screw a stopper on a place and tighten with demanded effort (29 — 39 Nanometers).
  8. Move drain capacity under the oil filter.

Replacement of the oil filter


  1. Move drain capacity under the oil filter.
  1. By means of one of types of special keys weaken the filter (see the illustration Tool kit, necessary for replacement of impellent oil and the oil filter). In the course of a reversing the case of the filter can appear is damaged that has no special value in case of its unequivocal replacement (the old filter for a reversing can be pierced simply a big screw-driver — prepare for collecting spilled oil). Manually finally turn out the filter from the block — remember that in it any amount of oil which should be let out in drain capacity continues to remain. Make sure that rubber sealing laying acted in film together with the filter if is not present, accurately separate it from a surface of the block of the engine.
  1. Pure rags carefully wipe a landing surface of the filter on the block. Once again make sure that old laying did not remain on the engine, in case of need use a scraper.
  2. Make sure that the new filter corresponds on a standard size removed from the car. Grease rubber sealing laying of the new filter by a thin layer of pure impellent oil. Screw the new filter in the engine, adhering specified by an arrow on its case of the direction of rotation. In order to avoid damage of laying do not apply to a tightening of the oil filter any keys. After the filter will nestle laying on a block surface, hold on it on 3/4 turns.
  3. Take from under the car all tools and materials — try not to overturn drain capacity. Lower the car on the earth.
  4. Fill in fresh oil in a reception mouth of the engine. For the purpose of minimization of losses use a funnel. Wait some minutes, having allowed oil to flow down in the pallet, then check its level on measuring щупу (see. Check of levels of liquids). If level is above the bottom mark in an edge щупа, start the engine, having provided circulation of fresh oil.
  5. Let's to the engine work within about a minute, again muffle it and at once glance under the car, checking, whether there are no leaks through a drain stopper and the polnopotochny filter. In case of need tighten a component allowing leak a little.
  6. During oil circulation on the engine, there is a filling of the new oil filter. Now it is necessary to check again level of oil and in case of need to add still its some quantity, having finished level to the top mark in an edge щупа (check make some minutes later after engine switching off — oil should manage to flow down completely in the case pallet).
  7. During the first several trips after change of impellent oil try as it is possible to check its level more often.
  8. The fulfilled oil merged from the engine is not subject to the secondary use and should be handed over on special place of acceptance. At all do not merge working off on the earth or in the sewerage — pour it in tightly closed container and at the first possibility hand over.
