Check of levels of liquids

Procedures of check of level the liquids made through each 400 km of run or weekly 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.



1 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 the listed components.

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

Impellent oil

2 Check of level of impellent oil is made by means of measuring probeа, the engine located on one side (address to the illustrations of the impellent compartment resulted in the given Chapter, for definition of its site). Щуп passes through a metal tube downwards, reaching a pallet bottom картера the engine.
3 Measurement of level of impellent oil is made before start of the engine or not less than through 15 mines after its deenergizing.

If to start measurement of level of impellent oil right after engine deenergizings, the oil part remains in the top part of the engine that will essentially be reflected in accuracy of indications probeа.

4 Take probe and dry wipe its edge pure rags or a paper towel. Enter probe up to the end back and again take it. The height of the site of an edge moistened with oil will correspond to oil level in the engine. This level should be between two labels on probeе.

5 For lifting of level of oil from the minimum label on probeе to maximum one litre of oil is required. Do not suppose falling of level below the minimum label since oil starvation can lead to engine damage. On the other hand, overflow of the engine by oil (доливание above the maximum mark) can be at the bottom замасливания of spark plugs, leaks of oil or failure of epiploons.

6 to add oils, unscrew a cover of the mouth located on a cover of a head of cylinders. After доливания some oil wait some minutes that oil level was stabilised, then pull out probe and again check up level. If it is required, add still oils. Close a cover of a mouth and tighten her hand.

7 Check of level of oil is the important preventive procedure. The engine should not consume more than 0.7 l of oil on 1.000 km of run. 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).

Engine cooler

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. Agree with local authorities about destruction of the used antifreeze.

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

9 Check of level of a cooler should be made regularly. Turn away a stopper on a broad tank. Liquid level normal if on the cold engine (temperature of a cooling liquid +20С) the upper edge of a red float is at one height with edge a branch pipe for filling. If liquid level lies more low, it is necessary to add a liquid. To add cooling liquid follows only on the cold engine to exclude its damage.

Do not uncover a jellied mouth of a broad tank or a cover of a radiator for check of level of a cooler before full cooling of the engine! Level in the tank fluctuates depending on engine temperature.

10 Banish the car and again measure cooler level. If to the necessary level it is required to add only a cooler small amount for this purpose it is possible to use pure water. However frequent additions of water will dilute antifreeze. To provide a normal parity of antifreeze and water, always add to the necessary level a demanded mix.
11 If cooler level falls regularly in system leak presence is possible. Examine a radiator, hoses, a cover of a mouth, a stopper plum and the water pump. If any leaks it is not revealed, make check of tightness of a cover of a broad tank and a radiator on HUNDRED BMW.
12 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 cooler starts to be pulled out, allow to the engine to cool down a little more, and only then uncover.
13 It is necessary to check a cooler condition also. It should be rather 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 cooler 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.

14 For check of frost resistance of a cooling liquid it is necessary to use ареометр (address also to Section Check of functioning of system of cooling and frost resistance of a cooling liquid). Type cooling liquid by means of a pear and read the float instrument. For maintenance of frost resistance to temperature-35S the volume parity of water and antifreeze makes 1: 1. If necessary add antifreeze according to Specifications.

15 Close a stopper of a broad tank and having made a trial trip again check up concentration of antifreeze.

Unduly high concentration of antifreeze conducts to decrease in effect of protective action and cooling properties of a liquid. It is shown at concentration of antifreeze about 60 %.

Brake liquid and coupling liquid

Fall of level of a brake liquid below mark MIN is displayed to the driver on a control panel. Nevertheless, it is recommended to examine the tank regularly.

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 (such as DOT 3 or 4 and DOT 5) can lead to refusal of brake system.

16 Main cylinder of brake system is established in a back left corner of an impellent compartment.

17 Level of a liquid is checked visually, on labels on the plastic tank established on the main cylinder. Liquid level should be between labels “MAX” and “MIN”. If 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.
18 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.
19 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.
20 Level of a liquid 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 Greasing of loops and locks of doors).
21 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 Section of Check of brake system).

22 If at check of level of a liquid the tank will appear is empty or nearly so is empty, the brake system or coupling system should be checked up on presence of leaks and is pumped over).

Liquid of a washer of a windscreen

23 Liquid for windscreen washing is in the plastic tank on the right side of an impellent compartment. Capacity of the tank is specified in Specifications.
24 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 with solvent of wax preservatives. 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 system of washing of the windscreen, 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.

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