Check of levels of liquids

Below procedures of check of level the liquids made through each 400 km of run or weekly are described. The description of other checks of levels of liquid can be found further in the Sections devoted to specific procedures of service. Irrespective of check intervals according to the schedule do not allow, that liquid followed under the car, such leaks indicate malfunction which it is necessary to eliminate immediately.

Liquids are the integral component of systems of greasing, cooling, brake and systems of washing of a windscreen. In view of a gradual expense and/or pollution of liquids in the course of normal operation of the car, it is necessary to replace them periodically. Familiarize with the Section “Types and volumes of applied greasings and liquids” in Specifications before starting a liquid dolivaniye in any of the listed components.

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

The card of viscosity of applied impellent oils

1 — cars with the diesel engine: BMW 525 tds

2 — cars with the petrol engine: BMW 520i, 528i, 535i, 540i

3 — cars with the diesel or petrol engine: special grades of BMW oil

Visual control of leakages of oil

At engine pollution by oil and the raised consumption of oil check places of its possible leaks.

CHECK

a) Open a cover of a jellied mouth and check laying.
b) Case ventilation: For example, ventilating hoses from a karterny part of the block of cylinders to the case of camshafts and from the case of camshafts to the air collector case.
c) Laying of a cover of a head of cylinders.
d) Laying of a head of cylinders.
e) Laying of the oil filter: The oil filter around a flange.
f) Sealing ring of a drain stopper.
g) Sensor of pressure of oil.
h) Consolidation of the pallet of a case.
i) Forward and back epiploons of distributive and cranked shaft.

In the presence of a leakage oil is distributed, as a rule, on a big surface of the engine that complicates definition of a place of leak. Search of a place of leakage of oil is necessary for making as follows:

PERFORMANCE ORDER

1. Wash out the engine. Spray the engine an autocleaner and after a while spray water. Previously cover the generator polyethylene.
2. Strew joints and consolidations at the engine with lime or a talc powder.
3. Check oil level. If necessary add.
4. Pass on the car. Thus oil gets warm and becomes more fluid. For this purpose it is necessary to pass on the car about 30 km with rather high speed.
5. After that stop the car and survey it a lamp. The found leaks eliminate.

Check of level of impellent oil

Shchup for measurement of level of oil

The cover of a jellied mouth of oil is located in a cover of a head of cylinders - each time before opening it, be convinced that a surface round a mouth the pure

Oil level in the engine should be checked each 1000 km of run. If necessary oil is necessary for adding.

The consumption of oil should not exceed 1 l on 1000 km of run. The bigger expense indicates wear of maslootrazhatelny caps.

PERFORMANCE ORDER CHECK REMOVAL INSTALLATION

1. At measurement of level of oil the car should stand on an equal horizontal platform.
2. After a stop of the engine wait for not less than 3 mines that oil merged in the case pallet.
3. Take out the index of level of oil and wipe it a pure rag.
4. Insert the level index into place against the stop and again take out. Level of oil should lie between two marks, it is desirable at level or is close from top of them - if it not so, add oil to the top label
5. Lifting of level of oil from the minimum label on щупе to maximum needs one liter of oil. Do not allow level falling below the minimum label since oil starvation can lead to engine damage. On the other hand, engine overflow by oil (the dolivaniye is higher than the maximum mark) can be at the bottom of a zamaslivaniye of spark plugs, leakages of oil or failure of epiploons.
6. Oil is filled in through a mouth on a cover of a head of cylinders. Watch that oil of the corresponding grade was added, for this purpose address to Specifications.

Check of level of oil is important preventive procedure. Continuous falling of level of oil indicates or existence of its leaks through the damaged epiploons or weakened connections, or on its burning out (internal leaks through worn-out piston rings or via directing plugs of valves). Besides, it is necessary to pay attention and to a condition of the oil. If oil has dairy color or in its structure it is possible to notice water drops, it indicates possible violation of tightness of laying of a head of cylinders or crack existence 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 щупа carry out on it big and index hand fingers. If will be thus found stuck on щуп particles of dirt or metal particles, oil it is necessary to replace (address to the Section Replacement of impellent oil and the oil filter)

Do not pour oil above the top label. It will lead to increase in a consumption of oil and can cause damages of the engine and the catalytic converter.

On models 520i, 523i, 528i the broad tank (the cooler tank) fastens to a radiator - make sure that level of liquid remains on or about “MAX” label.

On models 525tds the broad tank (the cooler tank) is located in a lateral part of an impellent compartment - uncover and add a cooler.

Engine cooler

Do not allow antifreeze hit on your skin or on the painted surfaces of the car. If it nevertheless occurred, immediately wash away 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 spilled 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.

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

Check of level of a cooler in the tank should be made regularly. Add 40 %/60 %-nuyu an antifreeze mix on a basis этиленгликоля from not containing lime pure water.

Do not uncover a jellied mouth of a broad tank or a radiator cover for check of level of a cooler before complete cooling of the engine! Level in the tank fluctuates depending on engine temperature. When the engine cold, level of a cooler should be higher than "LOW" label on the tank. In process of engine heating level should come nearer to “FULL” label. If it not so, let's to the engine cool down and then uncover the tank.

Banish the car and again measure cooler level. If to the necessary level it is required to add only small amount of a cooler, for this purpose it is possible to use pure water. However frequent additions of water will dilute antifreeze. To provide a normal ratio of antifreeze and water, always add to the necessary level a demanded mix.

If level of a cooler falls regularly, in system leak existence is possible. Examine a radiator, hoses, a cover of a mouth, a stopper plum and the water pump (address to the Section Replacement of liquid of system of cooling. Check of frost resistance of a cooler. Visual check of system of cooling) If any leaks it is not revealed, make check of tightness of a cover of a broad tank and a radiator in dealer office of the BMW service.

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 unscrew it to the first emphasis. If thus from under a cover steam or a cooler starts to escape, let's to the engine cool down a little more, and only then uncover.

It is necessary to check a cooler condition also. It should be rather pure. If liquid has brown or rusty color, it it is necessary to merge, wash out system and to fill it with a new mix. Even if the cooler looks normally, inhibitors of corrosion entering into its structure lose over time the efficiency therefore it is necessary to replace it through certain periods.

Check tightness if liquid level quickly goes down, address to the Section Check of system of cooling.

Brake liquid and coupling liquid

Brake liquid can harm your eyes and damage the painted surfaces of the car therefore be extremely careful at the treatment of her. Do not use brake liquid which long time stood opened or to which is more than one has some. Brake liquid has property to absorb moisture from air that can lead to dangerous loss of efficiency of brake system. Use only the recommended type of brake liquid. Mixing of various types of liquid (such as and DOT 5) can lead DOT 3 or 4 to refusal of brake system.

The tank of brake liquid/liquid of a hydraulic actuator of coupling is in an impellent compartment. It has two chambers, everyone on the contour of braking. The carving stopper has a ventilating opening. It is necessary to watch that it did not get littered.

The tank transparent that allows to watch liquid level in it. Decrease in level below a mark of MIN is signaled the driver by fire of a control lamp. Nevertheless, it is recommended to supervise from time to time the tank visually.

CHECK OF LEVEL OF BRAKE LIQUID

1. Remove a box of the microfilter of air of salon from the driver, address to the Section Replacement of the filter of air of salon.
2. Liquid level at the closed stopper should not be higher than a mark of MAX and marks of a label of "MIN" in the translucent tank are not lower - uncover and add liquid. For check of a control lamp press the contact specified by an arrow.
3. Fill in in system only brake liquid given in Specifications.
4. Owing to wear of a disk brake probably insignificant fall of level of brake liquid. It is considered normal.
5. If liquid level considerably goes down during a short period, it is a sign of leaks.
6. In this case it is necessary to reveal places of leakages of liquid urgently. It is best of all for making on HUNDRED.

Check of operability of a control lamp

PERFORMANCE ORDER

1. Include ignition. Release the parking brake.
2. Press a finger contact in a stopper of the tank, the shooter illustrations.
3. The assistant thus should watch, whether the control lamp in the dashboard block lights up. If the lamp does not light up, check an electric chain.
4. Establish into place a box of the microfilter of air of salon (The section Replacement of the filter of air of salon)

Liquid of a washer of a windscreen

Liquid for washing of a windscreen is in the plastic tank on the right in an impellent compartment.

The provision of a ball in a tube corresponds to liquid level in the tank. 0-empty, I - full

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

The tank glass - and faroomyvatel is located in the right part of an impellent compartment

The tank of a washer of intensive purification of glasses is located in the right part of an impellent compartment. Fill in a nonfreezing concentrate without diluting water.

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