Mercedes S-Class W-220

1. At the greasy engine and a big consumption of oil check places of leaks. The following places are for this purpose checked:

· Open a cover of a jellied mouth and check consolidation on existence of cracks or damages.
· Case ventilation: For example, a ventilating hose from a cover of a head of cylinders to a hose of absorption of air.
· Laying of a cover of a head of cylinders.
· Laying of a head of cylinders.
· Stopper of removal of oil (a round ring).
· Laying of the oil filter: a filter prileganiye to a flange.
· Laying of the pallet of a case.
· Forward and back epiploons of a cranked shaft.

At oil level above a mark of "max" there is a danger of damage of the engine or the catalyst.
If on the multipurpose display at the working engine there is an indication of level of impellent oil — address to the Section Precautionary and control lamps, and also messages of the multiinformation display on the registered malfunctions of the previous Chapter.

Precautionary indication of level of impellent oil — address to the Section the Multipurpose steering wheel, the multiinformation display.

1. Take щуп and dry wipe its edge pure rags or a paper towel. Enter щуп 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 labels on щупе.
2. Lifting of level of oil from the minimum label on щупе to maximum needs amount of oil specified in Specifications. 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.

3. To add oils, unscrew a cover of a mouth 2 on an illustration. After a dolivaniye of oil wait some minutes that level of oil was stabilized, then pull out щуп and again check level. If it is required, add still oils. Close a cover of a mouth and tighten her hand.

4. 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).

2. Check of level of a cooler in the tank should be made regularly, at strictly horizontal position of the car and the switched-off engine.
In a cold condition of cooling liquid its level should reach a mark-1-in a broad tank.
In a hot condition of cooling liquid level should be higher approximately on 1 cm.
Add 40 %/60 %-nuyu an antifreeze mix on a basis этиленгликоля with water. It is necessary to apply the structure specified in Specifications.

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 engines cold, level of a cooler should be higher than "MIN" label on the tank. In process of engine heating level should come nearer to «MAX» label. If it not so, let's to the engine cool down and then uncover the tank.

3. 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.
4. If level of a cooler falls regularly, in system leak existence is possible. Examine a radiator, hoses, a cover of a jellied mouth, drain jams and the water pump (address to the Section Check of functioning of system of cooling and frost resistance of cooling liquid. Liquid replacement). If leaks it is not revealed, make tightness check.
5. 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.

6. 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 intervals 7. For check of frost resistance of cooling liquid it is necessary to use the areometer.

1. The main cylinder of brake system is established in a back left corner of an impellent compartment.
2. Level of brake liquid is checked visually, on labels on the plastic tank established on the main cylinder. Level of liquid should be between «MAX» and «MIN» labels. If level is lower 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.
3. While the tank cover is removed, check liquid and the tank of the main cylinder on existence of pollution. If at it there are particles of a rust, dirt or a water drop, liquid from system it is necessary to merge and fill in the new.
4. After tank addition to the necessary level make sure that the cover is established exactly, in order to avoid leakages of liquid and/or dirt hit.
5. Liquid level in the main cylinder will fall slightly as a result of wear process of frictional overlays of brake shoes. There is no need to add it until level remains near «MIN» label; it will rise after replacement of slips. Very low level can indicate wear of brake shoes. Check them on wear existence (address to the Section Check of brake system).
6. If level of brake liquid constantly falls, immediately check all system on existence of leaks. Survey brake lines, hoses and shtutserny connections, together with supports, wheel cylinders and the main cylinder (address to Sections Check of brake system, Check of a condition and replacement of hoses of an impellent compartment, localization of leaks).
7. If at check of level of liquid the tank appears is empty or nearly is empty, the brake system should be checked on existence of leaks and is pumped over (address to Head Brake system).

2. 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 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 the windscreen washing, 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.

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