Replacement of impellent oil and the oil filter

Long contact of a skin to the fulfilled impellent oil is dangerous enough. Use a protective cream and put on gloves during carrying out of this procedure. The clothes which have become impregnated with oil replace immediately.

Frequent replacement of impellent oil is the main preventive procedure of service accessible to the mechanic-fan. Eventually oil is subject разжижению and to pollution that conducts to premature deterioration of the engine.


Impellent oil can be sucked away by means of a special probe (is available on filling stations) through a tube probeа measurements of level of oil. After that it is necessary to fill system with oil, as a rule.

Do not pour out the fulfilled oil together with a household waste or otherwise. It can cause environmental contamination.

Expediently at oil replacement to fix on the engine a label with mark of oil and its viscosity.

Application of oils of various types adversely affects engine work. It is not recommended to mix various marks of oils also. Impellent oils of the same type and mark, but various viscosity in necessary cases, in particular in inter-season period, can mix up.

It will be necessary for work for you:

- The tool for высасывания oils and capacity for oil gathering if oil is exhausted.
- If oil merges: the Viewing hole or the hydraulic garage lift with supports, and also a head for отворачивания stoppers of a drain aperture.
- The petrol engine: Tool HAZET 2169 for отворачивания covers of the oil filter.
- Capacity for gathering of oil in volume not less than 7 l.
Necessary operational materials/spare parts:
- Depending on the engine from 4.0 to 6.5 l of impellent oil. It is necessary to apply only the oil resolved by firm BMW, address to Specifications.
- Filtering element of the oil filter.
- Only if oil is not sucked away: the Aluminium lining for a stopper of a drain aperture. The stopper carving has external diameter of 12 mm, the lining has the size А12 x 15.5 and is sometimes delivered complete with the oil filter.
- Sealing ring for the case of the oil filter and depending on execution one or two sealing rings for the central bolt. The same variant of the engine can have two various executions of the filter. It is necessary to pay attention to it at purchase of spare parts.

Protect environment, at all do not pour out the fulfilled oil and do not delete it together with a household waste.

Removal of impellent oil


Impellent oil can or be removed through an aperture probeового the level index, or to merge from the pallet картера. For высасывания the special pump is required. Thus it is necessary to watch that the hose corresponded to a directing tube of the index of level. Devices for высасывания can be available on filling stations. However thus, as a rule, it is necessary to buy oil at the same station.

1 Warm up oil to working temperature. For this purpose pass on the car so that the index of temperature of a cooling liquid showed normal working temperature.

Operation of lifting and car installation on supports is connected with danger! Therefore before operation carrying out familiarise with Razdelom Poddomkrachivanie and towage


2 Establish the car on supports.

3 Open a crosswise screw-driver a cover under the pallet картера.


4 Substitute under the pallet картера

Watch that at отворачивании stoppers of a drain aperture hot oil has not got on hands.


5 Turn away a stopper of a drain aperture sideways the pallet картера and completely merge oil.

If at the fulfilled oil in a considerable quantity there is a metal shaving and deterioration products, it specifies in presence in the engine of places задиров, for example, in шатунных and radical bearings. To avoid it, after carrying out of repair of the engine it is necessary to clear oil channels and hoses carefully. It is in addition necessary to replace an oil radiator if it is available.


Replacement of the oil filter, execution with the central bolt

6 Turn out the central bolt-1 in the centre of a cover of the oil filter.


7 Uncover the filter-2 with the central bolt-1.
8 Wait, while will flow down oil from the filter case. After that take out filtering element-3. Wipe a rag flowing down oil.
9 Insert into the filter case a new filtering element.

Observe the instructions resulted on the filter.


10 Clear a cover of the oil filter.

11 Replace rubber rings (arrows with illustrations) on the central bolt and on a cover. New rings grease with impellent oil.


12 Insert directly from above a cover of the oil filter and press it.
13 Tighten the central bolt the moment 25 Н•м.

Replacement of the oil filter, execution with a carving cover

14 Turn away a carving cover a head on 36 mm. At the petrol engine the cover turns away special tool HAZET 2169.

15 Wait, while oil will flow out from the filter case. After that take out filtering element-1. Dripping oil wipe a rag


16 Insert into the case a new filtering element.

Observe the instructions resulted on the filter.


17 Replace rubber rings (with illustrations 6.15) on the central bolt and a cover. Grease new sealing rings with impellent oil.
18 Put directly from above a cover of the oil filter with маслопроводом and press it. Thus маслопровод enters into a corresponding aperture at the filter bottom.
19 Tighten a cover the moment 25 Н•м.

Filling of system with oil


20 Screw a stopper of a drain aperture with a new sealing ring and tighten densely but so that not to press. The moment of an inhaling for carving М12 (“17”) makes a key 25 Н•м, for carving М22 – 60 Н•м.
21 Fill in new oil through a jellied branch pipe of a cover of a head of cylinders. The volume of filled in oil is resulted in Specifications.

It is recommended to fill in at first on 1/2 l of oil less the than demanded volume. Excessive oil should be sucked away, consolidations of the engine and каталитический the converter otherwise can be damaged.


22 Start the engine and allow to it to work on single turns until the control lamp will go out. Stop the engine.
23 Having waited for 5 mines, check up level of oil and if necessary add oil. The difference between marks of level of oil Min and Max corresponds to volume of 1 l.
24 Close заслонку in a cover of an impellent compartment under the pallet картера and turn a crosswise screw-driver запорный an element on 1/4 turns, having fixed, thus, заслонку.
25 Pass on the car and check up tightness of a drain stopper and the oil filter. If necessary cautiously tighten.
