Mercedes E Class Petrol Workshop Manual W210 & W211 Series (eBook)

0. INTRODUCTION

Our Owners Manuals are based on easy-to-follow step-by-step instructions and advice, which enables you to carry out many, jobs yourself. Moreover, now you have the means to avoid those frustrating delays and inconveniences which so often result from not knowing the right approach to carrying out repairs which are often of a comparatively simple nature.

Whilst special tools are required to carry out certain operations, we show you in this manual the essential design and construction of such equipment, whenever possible, to enable you in many cases to improvise or use alternative tools. Experience shows that it is advantageous to use only genuine parts since these give you the assurance of a first class job. You will find that many parts are identical in the various models covered, but our advice is to find out before purchasing new parts – Always buy your spare parts from an officially appointed dealer.

Two four-cylinder engines are fitted, available in two different capacities. In the category "Four-cylinder Engines" with 16 valves you will find two engines within the model years in question: All engines, however, belong to the engine type "111" or "271", depending on the model series, as described above.

The V6 six-cylinder engine with 18 valves is fitted to models E240, E280 and E320. Most engines belong to the series "112", but "272" engines are fitted to model series W211. A V6 engine with 24 valves is fitted to models E350 (engine type "272"). Finally there is the V8 engine in the model range. Engine type "113" us used for both capacities.

The advantages of a multi-valve technology

One of the basic problems of a four stroke engine is the filling of the cylinders during the induction stroke with the necessary amount of the fuel/air mixture. The problem is made worse with increasing engine speed, as the opening period of the valves is shortened. Technicians refer to filling loss. To compensate the valve diameters are selected as large as possible so that more fuel/air mixture can enter, but the disadvantage is, of course, the larger diameter of the compression chamber.

This is the main reason for the introduction of the multi-valve technology. Four valve heads make up a larger opening area than two large valve heads and the size of the compression chamber can remain the same.

The advantages of the four valves can therefore be given as follows:

• Four valves enable larger opening diameters for inlet and exhaust gases. This helps the engine performance and the fuel consumption. This is one of the reasons that an engine with four valves per cylinder has a better consumption than a engine with two valves.

• Engines with four valves per cylinder have smaller valves and thereby less weight to be moved. A quicker response of the valve gear is therefore possible. One more advantage of this construction is that valve springs with a lower pressure are necessary to close the valves.

• Smaller valves are able to cool down quicker during the closing period.

• Engines with four valves per cylinder are also enable to obtain a higher compression ratio.

• The spark plugs can be centred in the compression chamber to provide the best possible igniting of the fuel/air mixture.

The vehicles covered in this manual are fitted with a six-speed manual transmission or an automatic transmission with five or seven speeds or a 4-Matic transmission.

The W210 and W211 series have a double wishbone front suspension with coil springs and telescopic shock absorbers and a stabiliser bar.

The so-called multi-link independent rear suspension comprises the rear axle carrier, provided with double-row angular ball bearings. The wheel carriers are guided by 5 specially located links, referred to as camber strut, pulling strut, pushing strut, track rod and spring links, the latter being the actual suspension arms. The hydraulic shock absorbers are fitted between the spring links and the body. A torsion bar is fitted to the spring links and the frame floor by means of a connecting link. The well-known level control system in other Mercedes Benz models is either fitted as standard or as an optional extra throughout the range.

Disc brakes on all four wheels, with dual-line brake system and brake servo is fitted. The handbrake acts on the rear wheels.

The rack and pinion steering with servo-assistance, introduced during the introduction of series W210 has been retained for series W211.

0.1. Vehicle Identification

The type identification plate is located at the R.H. side on the upper face of the radiator frame and contains the vehicle type, chassis number, permissible maximum weight and the permissible axle load on front and rear axle. The paint code is located in the plate opposite.

The chassis number can also be found in the engine compartment bulkhead. The first six numbers refer to the vehicle type, the 7th number refers to the steering and the 8th number to the transmission. The following six numbers are the actual serial number.

The engine number is stamped into the cylinder block on the side of the starter motor, immediately below the intake tube.

The code numbers and letters must always be quoted when parts are ordered. Copy the numbers on a piece of paper and take it to your parts supplier. You will save yourself and your parts department delays and will prevent you from ordering the wrong parts.

0.2. General Servicing Notes

The servicing and overhaul instructions in this Workshop Manual are laid out in an easy-to-follow step-by-step fashion and no difficulty should be encountered, lf the text and diagrams are followed carefully and methodically. The "Technical Data" sections form an important part of the repair procedures and should always be referred to during work on the vehicle.

In order that we can include as much data as possible, you will find that we do not generally repeat in the text the values already given under the technical data headings. Again, to make the best use of the space available, we do not repeat at each operation the more obvious steps necessary – we feel it to be far more helpful to concentrate on the difficult or awkward procedures in greater detail. However, we summarise below a few of the more important procedures and draw your attention to various points of general interest that apply to all operations.

Always use the torque settings given in the various main sections of the manual. These are grouped together in separate sub-sections for convenient reference.
