Replacement of impellent oil and oil filter

General information

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

Frequent replacement of impellent oil is the main preventive procedure of the service, to the available amateur mechanic. Eventually oil is subject to a razzhizheniye and pollution that conducts to premature wear of the engine.

Impellent oil can be extorted by means of a special probe (is available at filling stations) through a tube щупа 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 pollution.

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

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

Necessary tool

    Viewing hole or the hydrolift with supports (if oil is not sucked away). Head for an otvorachivaniye of a drain stopper. The special tool for a filter otvorachivaniye (a key for the filter, a tape key or the HAZET 2171-1 tool). Capacity for collecting oil (if oil is not sucked away) by capacity not less than 6 l.

Necessary spare parts and expendables

    Only if oil is not sucked away: an aluminum or copper sealing ring for a drain stopper (are sometimes delivered together with the oil filter). Oil filter. Necessary amount of the impellent oil resolved by the manufacturer, address to Specifications.

Oil filter

On sale there are filters with replaceable paper elements. Advantage them is that the filtroelement is subject to replacement only.

The oil filter consists of the case (1), a cover (2) and a filtroelement (3). The case of the oil filter fastens bolts on the block of cylinders instead of the former oil boss. Depending on the manufacturer on the case of the filter there can be a drain stopper (4). Filtroelementa of various manufacturers are interchangeable irrespective of the applied boss.

Removal of impellent oil

Impellent oil can be removed with a vysasyvaniye method, through an opening щупа or is merged from the case pallet.

For an otsasyvaniye the corresponding pump is required. Thus it is necessary to watch that the hose corresponded to an opening and had sufficient length.


    Diesel engine: Unscrew a cover on the filter case so that oil could merge from the filter case in the pallet. Suck away or merge oil. For this purpose lift and establish the car horizontally on supports or put the car over a viewing hole. Remove the bottom cover of an impellent compartment, address to the Section Removal and installation of the top cover of the engine / the bottom protection of an impellent compartment/stretcher. Put under a drain stopper capacity for the fulfilled oil. Watch that at a reversing of a drain stopper hot oil did not get on hands. Therefore at an otvorachivaniye of a stopper hold a hand horizontally.
    Turn out a drain stopper (1) of the pallet of a case (2) and completely merge the fulfilled oil.

If at the fulfilled oil in a large number there is a metal shaving and wear products, it indicates existence задиров, for example, in bearings of a cranked shaft and shatunny bearings. To exclude undesirable consequences of repair, it is necessary to clear oil channels and hoses carefully. Besides, it is necessary to clear an oil cooler if it is available.

    In summary wrap a drain stopper with a new sealing ring. Do not exceed the admissible moment of an inhaling, otherwise it can lead to loss of tightness and damages.
    Lower the car on wheels.

Replacement of the oil filter

The used filters or filtroelement are a special material and should be utilized in a special way.

Petrol engine


    Disconnect the oil filter. For this purpose there are special tools, for example, a tape key or the HAZET 2171-1 tool. Wipe a rag the flowed-out oil. On an accompanying illustration the oil filter of the 4-cylinder engine is shown.
    Clear by means of fuel a flange of the oil filter on the block of cylinders. Remove the remains of sealing laying. Grease with a thin layer of pure impellent oil a rubber sealing ring on the new filter. Fix by hand the new oil filter. When consolidation will lie down to the block of cylinders, turn the filter on 1/2 turns. If on the case of the filter there are instructions, follow of.

L engines 2.4, 3.0: Whether after replacement of the boss of the oil filter check freely pass the hoses going from the oil refrigerator to adjacent parts and, if necessary, modify position of the oil refrigerator.

Diesel engine of 1.9 l


    Unscrew by means of a key for filters, for example, HAZET 2169 or VW/AUDI-3417 a cover.
    Replace sealing rings and a filtroelement. Tighten a cover a key for filters the moment 25Нм.

Diesel engine of 2.5 l


    Unscrew a cover of the filter (1) key for filters on 32 mm, for example, HAZET 2169-2. Replace a filtroelement (3), and also a sealing ring (2) on a filter cover.
    Screw a filter cover on the case and fix it the moment 25Нм. Establish into place the top cover of the engine, address to the Section Removal and installation of the top cover of the engine / the bottom protection of an impellent compartment/stretcher.

System filling with impellent oil

At the diesel engine at the first start after replacement of oil watch that the engine at first worked only at single turns until the lamp of control of pressure of oil will go out. Only after that pressure of oil reaches the full value and it is possible to give gas to the engine. If gas to give at a burning lamp of control of pressure, owing to insufficient greasing the turbokompressor can be damaged.


    Open a cover (1) and fill in new oil via the jellied union of a cover of a head of cylinders.

It is recommended to pour in at first oils on 0.5 l less necessary volume, to start the engine, to warm up it and in some minutes the index to check oil level. If necessary, to add oil. Surpluses of oil should be sucked away, since consolidations of the engine and the catalytic converter otherwise can be damaged.

    Level of oil is in norm if lies in a range (In). If level of oil lies in a range (C), oil is necessary for adding to range level (In). On an accompanying illustration various executions of indexes of the level applied in engines of the AUDI A4 car are shown. If oil is in a range (And), to add it does not follow.
    Pass on the car and check tightness of a drain stopper and the oil filter, if necessary, carefully tighten a stopper.
    Through 3 mines after an engine stop once again check oil level, if necessary, modify.
    Establish the bottom cover of an impellent compartment, address to the Section Removal and installation of the top cover of the engine / the bottom protection of an impellent compartment/stretcher.
