Replacement of motive oil and oil filter

The long contact of skin with the fulfilled motive oil is quite dangerous. Use protective cream and put on gloves during this procedure. Replace the clothes which became impregnated with oil immediately.

Frequent replacement of motive oil is the main preventive procedure of service, to the available amateur mechanic. Eventually oil is subject to fluidifying and pollution that leads to premature wear of the engine.


Motive oil can be sucked away by means of the special probe (is available at gas stations) through a tube of the probe of measurement 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 household waste or otherwise. It can cause environmental pollution.

Expediently when replacing oil to fix on the engine a label with brand of oil and its viscosity.

Use of oils of various types adversely affects operation of the engine. It is not recommended to mix various brands of oils also. Motive oils of the same type and brand, but various viscosity in necessary cases, in particular in off-season, can mix up.

It will be necessary for work for you:

- The tool for exhaustion of oil and capacity for collecting oil if oil is exhausted.
- If oil merges: A viewing hole or the hydraulic garage elevator with supports, and also a head for an otvorachivaniye of a stopper of a drain opening.
- Petrol engine: The HAZET 2169 tool for an otvorachivaniye of a cover of an oil filter.
- Capacity for collecting oil not less than 7 l.
Necessary operational materials / spare parts:
- Depending on the engine from 4.0 to 6.5 l of motive oil. It is necessary to apply only the oil resolved by BMW, address Specifications.
- The filtering element of an oil filter.
- Only if oil is not sucked away: Aluminum laying for a stopper of a drain opening. The carving of a stopper has the outer diameter of 12 mm, laying has the A12 x 15.5 size and is sometimes delivered complete with an oil filter.
- A sealing ring for the case of an oil filter and depending on execution one or two sealing rings for the central bolt. The same version of the engine can have two various executions of the filter. It is necessary to pay attention to it upon purchase of spare parts.

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

Removal of motive oil


Motive oil can or be removed through an opening of the shchupovy index of level, or to merge from the case pallet. Exhaustion requires the special pump. At the same time it is necessary to watch that the hose corresponded to the directing tube of the index of level. Devices for exhaustion can be available at gas stations. However at the same time, as a rule, it is necessary to buy oil at the same station.

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

Lifting operation and installations of the car on supports is connected with danger! Therefore before carrying out operation study Poddomkrachivaniye's Section and towage


2 Install the car on supports.

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


4 Substitute under the case pallet

You watch that at an otvorachivaniye of a stopper of a drain opening hot oil did not get on hands.


5 Turn off a stopper of a drain opening sideways of the pallet of a case and completely merge oil.

If at the fulfilled oil in a large number there is a metal shaving and products of wear, it indicates existence in the engine of places of zadir, for example, in conrod and radical bearings. To avoid it, after carrying out 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 an oil filter, execution with the central bolt

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


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

Observe the instructions given on the filter.


10 Clear a cover of an oil filter.

11 Replace rubber rings (arrows with illustrations) on the central bolt and on a cover. Oil new rings motive.


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

Replacement of an oil filter, execution with a carving cover

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

15 Wait until oil flows out from the filter case. After that take out the filtering element-1-. Wipe the dripping oil a rag


16 Insert the new filtering element into the case.

Observe the instructions given on the filter.


17 Replace rubber rings (with illustrations 6.15) on the central bolt and a cover. Oil new sealing rings motive.
18 Put directly from above a cover of an oil filter with an oil pipeline and press it. At the same time the oil pipeline enters the corresponding opening at the filter bottom.
19 Tighten a cover the moment of 25 N • m.

Filling of system with oil


20 Screw a stopper of a drain opening with a new sealing ring and tighten densely, but so that not to press. The inhaling moment for M12 carving (a key "17") makes 25 N • m, for M22 carving – 60 N • m.
21 Fill in new oil through a jellied branch pipe of a cover of a head of cylinders. The volume of the filled-in oil is specified in Specifications.

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


22 Start the engine and let's it work on single turns until the control lamp goes out. Stop the engine.
23 Having waited for 5 min., check the level of oil and if necessary add oil. The difference between marks of level of Min and Max oil corresponds to the volume of 1 l.
24 Close the gate in a cover of a motive compartment under the pallet of a case and turn the crosswise screw-driver a locking element on 1/4 turns, having fixed, thus, the gate.
25 Pass on the car and check tightness of a drain stopper and an oil filter. If necessary carefully tighten.
