Check of levels of liquids, the control of leaks

Procedures of check of levels of the liquids, made each 1000 km of run, monthly and before each distant trip are more low described. The description of other checks of levels of a liquid can be found further in the Sections devoted to specific procedures of service. Irrespective of check intervals under the schedule do not suppose, that the liquid followed under the car, such leaks specify in malfunction which should be eliminated immediately.

Liquids are the integral component of systems of greasing, cooling, brake and systems of washing of a windscreen. In view of the gradual expense and-or pollution of liquids in the course of normal operation of the car, it is necessary to replace them periodically. Familiarise with Section «Types and volumes of applied greasings and liquids» in Specifications before to start to доливанию liquids in any of listed a component.

At any check of level of a liquid the car should stand on an equal surface.

The visual control of leaks


  1. Remove 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.
  2. Remove the bottom 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.
  3. Visually check up on presence негерметичности, attritions, cracks and damages following pipelines, hoses and joinings:
    • Топливопроводы;
    • Hoses of system of cooling and heating;
    • Brake pipelines and hoses;
    • Hydraulic lines of the amplifier of a wheel;
    • Conditioner lines.

Impellent oil


  1. At the greasy engine and the big expense of oil check up places of leaks. Following places are for this purpose checked:
    • Open a cover of a jellied mouth and check up a lining on presence of cracks or damages.
    • Ventilation картера: For example, a ventilating hose from a cover of a head of cylinders to a hose всасывания air.
    • Lining of a cover of a head of cylinders.
    • Lining of a head of cylinders.
    • Stopper of removal of oil (round ring).
    • Lining of the oil filter: прилегание the filter to a flange.
    • Pallet lining картера.
    • Forward and back epiploons of a cranked shaft.
  2. As at presence негерметичности oil extends on the big surface of the engine, places of leaks at once to define difficult. For detection of leaks operate as follows:
  3. Wash out the engine as follows: the generator close a plastic package. Spray the engine a usual cold cleaner and through short time wash out water on a car wash.
  4. Places of interface and epiploons on the engine strew outside известью or talc.
  5. Check up oil level, if necessary add.
  6. Make a trial trip. As oil in the hot engine reduces the viscosity and faster acts in places of leaks, it is necessary to execute a trial trip on distance about 30 km on a high-speed line.
  7. In summary investigate the engine by means of a lamp and localise places of leaks, having eliminated malfunctions.

Check of level of oil probeом

Check of level of oil is the important preventive procedure. Constant falling of level of oil specifies or in presence of its leaks through the damaged epiploons or ослабшие connections, or on its burning out (internal leaks through the worn out piston rings or through directing plugs of valves). Besides, it is necessary to pay attention and to a condition of the oil. If oil has dairy colour or in its structure it is possible to notice water drops, it specifies in possible infringement of tightness of a lining of a head of cylinders or crack presence in a head or the block of cylinders. In this case the engine should be repaired immediately. Each time at measurement of level of oil before edge rubbing probeа spend on it big and index hand fingers. If will be thus found out stuck on probe particles of a dirt or metal particles, oil it is necessary to replace (address to Section Replacement of impellent oil and the oil filter).


  1. Pass on the car to warm up the engine, and stop the car on an equal platform.
  1. After a stop of the engine wait not less than 3 mines that oil has flown down in the pallet.
  1. Take out the index of level of oil of the engine and wipe its pure rag.
  1. Then insert the index into an aperture against the stop and again take out it.
  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 different variants of execution of indexes of level are shown. If oil is in a range () to add it does not follow.

Surpluses of oil (above a range) are necessary for sucking away, since linings or epiploons of the engine and каталитический the converter otherwise can be damaged.

  1. At the raised loadings on the engine, for example, at long movement on a motorway in the summer, towage of the trailer or movement in mountain district oil level should lie in the top part of a range ().
  2. Filling of system with oil is made through a stopper of a cover of a head of cylinders. Apply a demanded grade of oil, do not use an additive, address to section System of greasing of the engine.

The expense of impellent oil

Max. 0.8 l/1000 of km, depending on style of driving.

The expense of oil the engine can be defined only after passage of a long distance. During the period обкатки it can exceed the resulted value. Frequent movement with high turns of the engine conducts to increase in the expense of oil.

Cooling liquid of the engine

Do not suppose antifreeze hit on your skin or on the painted surfaces of the car. If it nevertheless has occurred, immediately смойте antifreeze a plentiful quantity of water. Antifreeze is extremely toxic in a case hit in an organism. Never leave it without supervision in the open container or spilt on a floor; or animals its sweet smell can involve children and they can drink it.

All cars considered in the given Management, are equipped by system of cooling with superfluous pressure of compensatory type. The white plastic broad tank is located in an impellent compartment and connected by a hose to a radiator. In process of a warming up of the engine in the course of its work the extending liquid fills a tank. At cooling of the engine the liquid automatically arrives back in cooling system that provides maintenance of constant level.

Check of level of a liquid in the tank should be made regularly, at strictly horizontal position of the car and the switched off engine.

Level of a cooling liquid at the cold engine (temperature nearby + 20°С) should be between marks MAX and MIN on a broad tank. At the warm engine liquid level can be a little above mark MAX.

Do not uncover a jellied mouth of a broad tank or a cover of a radiator for check of level of a liquid before full cooling of the engine!

Banish the car and again measure liquid level. If to the necessary level it is required to add only a small amount it is possible to use pure water. However frequent additions of water will dilute antifreeze. To provide a normal parity (40 %/60 %) antifreeze and water, always add to the necessary level a demanded mix of the antifreeze specified in Specifications, on a basis этиленгликоля and waters.

Great volume of a cold cooling liquid fill in only at the cold engine to avoid engine damages.

If liquid level falls regularly in system leak presence is possible. Examine a radiator, hoses, a cover of a jellied mouth, drain stoppers and the water pump (address to Section Check of a condition and replacement of hoses of an impellent compartment, localisation of leaks). If leaks it is not revealed, make check of tightness of a cover of a broad tank and a radiator in conditions HUNDRED.

If you need to uncover, wait, while the engine completely will cool down, then wrap up a piece of thick rags round a cover and turn away it to the first emphasis. If thus from under a cover steam or a liquid starts to be pulled out, allow to the engine to cool down a little more, and only then uncover.

It is necessary to check a liquid condition also. It should be concerning pure. If the liquid has brown or rusty colour, it it is necessary to merge, wash out system and to fill with its new mix. Even if the liquid looks normally, entering into its structure ингибиторы corrosion in due course lose the efficiency, therefore it is necessary to replace it through certain time intervals.

For check of frost resistance of a cooling liquid it is necessary to use ареометр (address to an illustration and Specifications).

Brake liquid

The brake liquid can harm your eyes and damage the painted surfaces of the car, therefore be extremely cautious at the reference with it. Do not use a brake liquid which long time stood opened, or which more than one year. The brake liquid has property to absorb a moisture from air that can lead to dangerous loss of efficiency of brake system. Use only the recommended type of a brake liquid. Mixing of various types of a liquid can lead to refusal of brake system.

The tank of a brake liquid is behind at the left in an impellent compartment. It has two chambers, everyone for the brake contour.

Level of a brake liquid is checked visually, on labels on the plastic tank established on the main cylinder. At the closed cover level of a brake liquid should be between marks MAX and MIN.Если level below admissible, at first wipe top of the tank and a cover pure rags to prevent dirt hit in system after cover removal. Add to the necessary level the recommended liquid, but do not pour.

While the tank cover is removed, check up a liquid and the tank of the main cylinder on presence of pollution. If at it there are particles of a rust, a dirt or a water drop, a liquid from system it is necessary to merge and fill in the new.

After addition of the tank to the necessary level make sure that the cover is established exactly, in order to avoid leaks of a liquid and-or dirt hit.

Liquid level in the main cylinder will fall slightly as a result of wear process of frictional overlays brake колодок. There is no necessity to add it until level remains near a label «MIN»; it will rise after replacement of overlays. Very low level can specify in deterioration brake колодок. Check up them on deterioration presence (address to Section of Check of brake system. Adjustment of a lay brake).

If level of a brake liquid constantly falls, immediately check up all system on presence of leaks. Survey brake lines, hoses and штуцерные connections, together with supports, wheel cylinders and the main cylinder (address to Sections of Check of brake system. Adjustment of a lay brake, Check of a condition and replacement of hoses of an impellent compartment, localisation of leaks).

If at check of level of a liquid the tank appears is empty or nearly so is empty, the brake system should be checked up on presence of leaks and is pumped over (address to the Head Brake system).

Liquid ГУР

The tank of hydraulic system of the amplifier of a steering is in a back part of an impellent compartment. Address to Section Check of level of a liquid of system of hydrostrengthening of a wheel.

Liquid of a washer of a windscreen

The concentrate стекломоющего means is easily combustible.

At the reference with a concentrate стекломоющего means application of fire, an open flame and smoking are forbidden.

Open a cover and check up visually liquid level.

If necessary add a mix from a concentrate for a sink of glasses and potable water.

Capacity of the tank is resulted in Specifications.

In areas with a temperate climate it is possible to fill system with usual water, but it is recommended to add in water means for washing of glasses. The tank should be filled no more, than on two third that there was a free space on a case of expansion of water at freezing. In areas with cold environmental conditions it is necessary to use special antifreeze for the windscreen washing, reducing a freezing point of a liquid which can be got in any shop of automobile accessories. Usually it is on sale in the concentrated or ready kind. If you have got the concentrated antifreeze, mix it with water according to the instruction of the manufacturer on packing.

For models with warmed jets, as a rule, sufficient frost resistance of a mix to-10°S.

Do not use antifreeze of system of cooling - it will damage the painted surfaces of the car.

Check up adjustment of jets, address to Section Removal and jet installation стеклоомывателя a windscreen.
