Compensation of engine oil and fat filter

The long contact of skin with the working engine oil is quite dangerous. Use protective cream and put on gloves during this procedure. You replace the clothes impregnated with oil not staying.

Regular and frequent compensation of engine oil is a preventive main procedure of service which is available on hand to the mechanic's fan. During time rasschischeniju oil and pollution is subordinated that leads to early sale of the motor.


It is possible to extort engine oil by means of the special probe (существуемо on gas stations) thanks to the listener of schtschupa of measurement of level of oil. Then are necessary to fill, as a rule, system oil.

Do not pour out thoroughly working oil together with the budgetary garbage or otherwise. It can cause environmental pollution.

It is expedient to strengthen at compensation of oil the adherent with brand of oil and its viscosity on the motor.

The Pig of Various Types appendix affects operation of the motor adversely. Also not recommended to mix various Pig brands. Engine oils the same type and brands, but various viscosity in necessary cases, can mix up including in time between seasons.

Necessary tool:

  • smotrowaja a hole or the hydro-elevator with regiments (if oil not otsassywajetsja).
  • The head for drain stopper otworatschiwanija.
  • The special tool for filter otworatschiwanija (keys to the filter, a key of a tape or the HAZET 2172 tool).
  • Power for oil duty (if oil not otsassywajetsja) is not less power than 6 l.

    • Necessary spare parts and materials of the edition:

  • Only if oil not otsassywajetsja: aluminum or copper uplotnitelnoje a ring for a drain stopper (are sometimes delivered together with the fat filter).
  • Fat filter.
  • Necessary amount of engine oil. Use oil which is allowed the producer, address specifications.

    • Removal of engine oil

    Engine oil can also be on removal from the wyssassywanija method, by means of the probe, opening of schtschupa.


    You heat the motor up to the working temperature (temperature of oil of +60 °C).

    Lift the car horizontally.

    Replace under kartera peel power for duty of thoroughly working oil.

    Pull out (2) stoppers of a drain (1) from kartera peel and completely you pull together oil.

    If there are at thoroughly working oil in a large number a metal chip and products of sale, it designates on existence of sadirow, for example, in camps of a bent shaft and schatunnych of the camp. For an exception of damages after the made repairs it is necessary to clean fat channels and hoses carefully. It is in addition necessary if существуемо to replace the fat heater.


    Then with in a new way uplotnitelnym from a ring it is necessary to screw up a drain stopper. It is not necessary to pass it is necessary the train moments specified in specifications, otherwise it can lead to violation of density and damages.

    Lower the car on wheels.

    Compensation of the fat filter

    Prevent below the fat filter. For otworatschiwanija of the fat filter there is a special tool, for example, of HAZET 2172 (2). It is possible to pierce also the filter (1) along with it from the screw-driver, - you are prepared for duty of the spilled oil.


    You clean a flange of the fat filter from fuel. Remove the possible remains of transferring from a flange.

    You grease new transferring of the fat filter with a thin layer of engine oil.

    You firmly tighten the new fat filter only from effort of a hand., After transferring of priljaschet to a flange, dowernite of filters on a change floor. If draw the attention of the remark which are given in a filter body.

    You tighten a stopper of a waste opening with a new ring of ukasyannym in specifications of the moment.

    Gas station of engine oil

    At the first start of a turbodiesel after compensation of oil it is necessary to follow that the motor worked at not aggravated changes at first until the control lamp of pressure of oil does not lose force. Only it is possible to increase gas after achievement of necessary pressure of oil. If gas at the burning control lamp is given, the turbocompressor can be damaged owing to insufficient amount of oil.


    Gas station of oil will be specially, saliwnuju equipped with a cover a neck in a cover of the head of the cylinders (made watch office check of levels of liquids, control of a vytecheniye).

    At compensation of oil you use new oil such type and whenever possible the same brand. For the purpose of minimization of rasbrysgiwanija you use a funnel. At each compensation of oil you strengthen a sign on the motor, on volume you designate brand and viscosity of the filled-in oil.

    The oil 0.5 l smaller recommended to fill in at first. Heat the motor and several minutes, by means of the list, check oil level if dolejte is necessary. You delete excess of oil, the condensation of the motor and the catalytic reformer can be damaged differently.


    Dolejte oil to sign MAX on an edge measuring schtschupa (watch office check of levels of liquids, control of a vytecheniye). If the level of oil is higher, oil has to extort abundance.

    After test drive you check density of disembarkation of a stopper of a drain and the fat filter, it is necessary carefully dolejte oil if.

    In 3 minutes you check oil level again after a motor break if it is necessary you delete dolejte or oil.
