Replacement of impellent oil and the oil filter

The general information

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 extorted 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.

The necessary tool

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

Necessary spare parts and account materials

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

The oil filter

On sale there are filters with replaceable paper elements. Their advantage consists that is subject to replacement only фильтроэлемент.

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

Removal of impellent oil

Impellent oil can be removed a method высасывания, through an aperture probeа or is merged from the pallet картера.

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


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

If at the fulfilled oil in a considerable quantity there is a metal shaving and deterioration products, it specifies in presence задиров, for example, in bearings of a cranked shaft and шатунных 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.

  1. 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.
  1. Lower the car on wheels.

Replacement of the oil filter

The used filters or фильтроэлементы are a special material and should be utilised in special way.

The petrol engine


  1. Disconnect the oil filter. For this purpose there are special tools, for example, a tape key or tool HAZET 2171-1. Wipe a rag the flowed out oil. On an accompanying illustration the oil filter of the 4-cylinder engine is shown.
  1. Clear by means of fuel a flange of the oil filter on the block of cylinders. Remove the rests of a sealing lining.
  2. Grease with a thin layer of pure impellent oil a rubber sealing ring on the new filter.
  3. 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 filter case there are instructions, follow them.

Engines 2.4, 3.0 l: whether After replacement of a cartridge of the oil filter check up freely pass the hoses going from an oil refrigerator to adjacent parts and, if necessary, modify position of an oil refrigerator.

The diesel engine of 1.9 l


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

The diesel engine of 2.5 l


  1. Turn away a cover of the filter (1) key for filters on 32 mm, for example, HAZET 2169-2. Replace фильтроэлемент (3), and also a sealing ring (2) on a filter cover.
  1. Screw a filter cover on the case and fix its moment 25Нм.
  2. Establish into place the top cover of the engine, address to 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 oil replacement watch that the engine at first worked only on single turns until the lamp of the 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 the control of pressure, owing to insufficient greasing can be damaged турбокомпрессор.


  1. Open a cover (1) and fill in new oil through 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 than necessary volume, to start the engine, to warm up it and in some minutes the index to check up oil level. If necessary, to add oil. Surpluses of oil should be sucked away, since consolidations of the engine and каталитический the converter otherwise can be damaged.

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