Repair and car operation

Change of impellent oil and the oil filter (each 4800 km (3000 miles) run or times in 3 months)

Regular and frequent changes of impellent oil and the oil filter are the most important preventive procedure of routine maintenance of the car, the amateur mechanic lying in competence. Its importance is defined by a tendency of engine oils to a razzhizheniye eventually that results in premature wear of internal components of the engine.

In spite of the fact that some sources recommend to make change of the oil filter only every second change of oil, originators of this Management, being based on insignificance of cost of the new filter and relative simplicity of performance of procedure, and also in view of relevancy of brought advantage, advise to change the filter each time at change of impellent oil.

Prepare all necessary for performance of this procedure materials and tools.

Tools and materials necessary for performance of change of impellent oil and the oil filter.

1 — the Drain capacity - should be superficial, but rather wide for containment of all volume of merged oil and prevention of its passage
2 — Rubber gloves - When unscrewing a drain stopper and the oil filter oil inevitably gets on hands (gloves will help to avoid burns)
3 — the Collar - In certain cases the drain stopper with great difficulty gives in an otdavaniya and a collar in a combination to a replaceable head is urged to facilitate procedure performance
4 — the Replaceable face head - In a combination to a collar or a ratchet drive is used for an otdavaniye of a drain stopper (should correspond to it on the size - preferably use of 6 inch heads)
5 — the Key for a svinchivaniye of the oil filter - Such, tape type the key demands existence of sufficient free space round the filter
6 — the Key for a svinchivaniye of the oil filter - the Key of this type puts on on a bottom of the filter and can rotate by means of a collar or mount (under different the size filters are issued keys of various diameter)

For collecting spilled oil near at hand it is necessary to have near at hand enough of rags, old newspapers or paper towels. Access under the car will essentially be facilitated after posting of the last by means of the winch, installation on a platform or over a viewing hole, or fixings in the lifted condition by means of props.

At all do not perform any works under the car, fixed in the lifted condition only by means of a jack (ов)!

If you are going to start the independent change of oil first in the life and the filter, previously familiarize with an arrangement of all components concerning the forthcoming operation (the oil filter and a drain stopper). In the course of carrying out work the engine and sections of system of release will be warmed up to considerable temperatures therefore it is necessary to think over in advance each movement in order to avoid a touch to hot surfaces.

PERFORMANCE ORDER

Warm up the engine to normal working temperature. Time necessary for warming up of the engine is reasonable for spending for preparation for work of all necessary materials and tools. The demanded grade of oil for really taking place conditions can be picked up by means of information provided in subsection Recommended greasings and liquids at the beginning of this Chapter.
After impellent oil will appear rather heated-up (in the warmed-up condition it follows from the engine easier and better washes away all accumulated in a case шлам), поддомкратьте the car and establish it on props. Remember that safety - above all!
Place all necessary materials, rags, newspapers and tools under the car. Establish the prepared capacity under a drain opening in the case pallet. Having capacity remember that at the beginning oil will follow under a certain pressure, but in process of decrease of its quantity, the stream will gradually weaken, changing respectively the trajectory.
Trying not to touch the warmed-up surfaces of system of release, use a cap or face key for an otdavaniye of the drain stopper being in the lowest point of the pallet of a case. Depending on that, oil is how strongly warmed up, you can use or not at a finishing stage of a vyvinchivaniye of a stopper protective gloves.

The drain stopper is in the lower part of the pallet of a case of the engine and should be unscrewed by means of a replaceable face head or a cap key - do not apply to a stopper vyvinchivaniye a rozhkovy key is it is fraught with a rounding off of corners of a head of a stopper.

Let's to oil flow down completely in drain capacity. Probably, in process of weakening of a pressure of a stream it is required to move capacity a little.
After oil will stop to follow from a case wipe a drain stopper pure rags. Otherwise, the small metal sawdust which has stuck to a stopper will lead to immediate pollution of fresh oil.
Wipe a surface round a drain opening and establish into place a stopper, having strongly tightened it a key. If available there is a dinamometrichesky key, tighten a stopper with demanded effort.
Move drain capacity under the oil filter.
For a reversing of the filter use one of types of special keys (see an illustration). Use of a key of chain or tape type can lead to irreversible destruction of the filter, however it has no special value as it in any case is subject to replacement.
Completely remove the old filter. Be careful - it will be filled with oil. Merge oil from the filter in capacity.
By comparison make sure of compliance of types of old and new filters each other.
Pure rags wipe a landing surface under the filter on the engine block, having removed from it all traces of oil and stuck dirt and шлама. Having examined the removed filter, make sure that its rubber laying did not remain stuck to the engine block. If it occurred, remove laying from the block (use for simplification of procedure by a small lamp).
Grease laying of the new filter by a thin layer of pure impellent oil.
Following the instructions of the manufacturer provided on packing of the new filter, establish the last on the engine. The majority of manufacturers warn against use for a twisting of the filter of any type of keys in order to avoid damage of sealing laying owing to a tightening with excessive effort.
Take from under the car all tools, rags, newspapers, drain capacity, trying not to spill from the last oil, then lower the car on the earth.
Move in impellent and find a cover of a mouth of the gulf of oil.
In order to avoid a razbryzgivaniye, fill in oil in a mouth through a funnel.
Fill in in the engine about 4 (3,7) l of oil. Wait some minutes, let's to oil flow down in the pallet, then check its level on measuring щупу (The section of Check of levels of liquids (each 400 km (250 miles) run or weekly)). If level of oil is above a mark of ADD to (Add), start the engine, having provided circulation on it fresh oil.
Let's to the engine work within about 1 minute, then switch off it. At once glance under the car and make sure of lack of traces of leakages of oil around a drain stopper and the oil filter. In case of need tighten components.
After new oil проциркулировало on the engine also filled the filter again check its level on щупу. If necessary make having added.

During the first several trips after change of impellent oil as it is possible pay attention to existence of signs of leaks more often and regularly check oil level.

The old oil merged from the engine in its present condition to the repeated use is not subject and should be handed over in utilization. Special utilizatsionny points and car-care center workshops usually accept working off which after refinement can be used further. After the merged oil will cool down it should be poured in suitable, it is desirable tightly closed container for transportation in place of acceptance.
