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.

Bolts and nuts should be assembled in a clean and very lightly oiled condition and faces and threads should always be inspected to make sure that they are free from damage burrs or scoring. DO NOT degrease bolts or nuts.

All joint washers, gaskets, tabs and lock washers, split pins and "O" rings must be replaced on assembly. Seals will, in the majority of cases, also need to be replaced, if the shaft and seal have been separated. Always lubricate the lip of the seal before assembly and take care that the seal lip is facing the correct direction.

References to the left-hand and right-hand sides are always to be taken as if the observer is at the rear of the vehicle, facing forwards, unless otherwise stated.

Always make sure that the vehicle is adequately supported, and on firm ground, before commencing any work on the underside of the car. A small jack or a make shift prop can be highly dangerous and proper axle stands are an essential requirement for your own safety.

Dirt, grease and mineral oil will rapidly destroy the seals of the hydraulic system and even the smallest amounts must be prevented from entering the system or coming into contact with the components. Use clean brake fluid or one of the proprietary cleaners to wash the hydraulic system parts. An acceptable alternative cleaner is methylated spirit, but if this is used, it should not be allowed to remain in contact with the rubber parts for longer than necessary. It is also important that all traces of the fluid should be removed from the system before final assembly.

Always use genuine manufacturer's spares and replacements for the best results.

Since the manufacturer uses metric units when building the cars it is recommended that, these are used for all precise units. Inch conversions are given in most cases but these are not necessarily precise conversions, being rounded off for the unimportant values.

Removal and installation instructions, in this Workshop Manual, cover the steps to take away or put back the unit or part in question. Other instructions, usually headed "Servicing", will cover the dismantling and repair of the unit once it has been stripped from the vehicle it is pointed out that the major instructions cover a complete overhaul of all parts but, obviously, this will not always be necessary and should not be carried out needlessly.

There are a number of variations in unit parts on the range of vehicles covered in this Workshop Manual. We strongly recommend that you take care to identify the precise model, and the year of manufacture, before obtaining any spares or replacement parts.

0.5. Jacking up the Vehicle

To prevent damage to the underside of the vehicle, apply a jack or chassis stands only to the points specified below:


Fig. 0.1 – Jacking up the front end of the vehicle. The L.H. view shows where the jack is placed underneath the front crossmember. The R.H. view shows the jacking up of the rear of the vehicle. The jack is placed underneath the centre piece of the rear axle

The front end of the vehicle should be lifted up by placing a jack underneath the transverse crossmember of the front suspension as shown in Fig. 0.1, taking care not to damage the undercover for the engine compartment. To lift the rear end of the vehicle, place the jack underneath the rear axle centre piece, as shown in Fig. 0.1 on the R.H. side. Make sure the jack is sufficient to take the weight of the vehicle. The vehicle can also be jacked up on one side. In this case place the jack underneath the hard rubber inserts near the wheels, as shown in Fig. 0.2 on one side of the vehicle. Never place a jack underneath the oil sump or the gearbox to lift the vehicle.


Fig. 0.2 – Jacking up one side of the vehicle. Place the jack (2) underneath the side of the body as shown. Chassis stands are placed at the position shown.


Fig. 0.3 – Three-legged chassis stands are the safest method to support the vehicle when work has to be carried out on the underside of

Chassis stands should only be placed on the L.H. and R.H. sides under the side of the body without damage to the paintwork. Use chassis stands of the construction shown in Fig. 0.3, should be used, but again make sure that they are strong enough to carry the weight of the vehicle. Make sure the vehicle cannot slip off the stands.

Before lifting the front of the vehicle engage first or reverse gear when a manual transmission is fitted or place the gear selector lever into the "P" (park) position when an automatic transmission is fitted. Use suitable chocks and secure the front wheels when the rear end of the vehicle is jacked up.

Always make sure that the ground on which the vehicle is to be jacked up is solid enough to carry the weight of the vehicle.

Note: It is always difficult to raise a vehicle first on one side and then on the other. Take care that the vehicle cannot tip-over when the first side is lifted. Ask a helper to support the vehicle from the other side. Never work underneath the vehicle without adequate support.

0.6. Recommended Tools


Fig. 0.4 – A double open-ended spanner in the upper view and an open-ended/ring spanner in the lower view. Always make sure that the spanner size is suitable for the nut or bolt to be removed and tightened.

To carry out some of the operations described in the manual you will need some of the tools listed below:

As basic equipment in your tool box you will need a set of open-ended spanners (wrenches) to reach most of the nuts and bolts. A set of ring spanners is also of advantage. To keep the costs as low as possible we recommend a set of combined spanners, open-ended on one side and a ring spanner on the other side. Fig. 0.4 shows a view of the spanners in question. Sockets are also a useful addition to your tool set.


Fig. 0.5 – A graduated disc is used to “angletighten” nuts and bolts. “Torx” head bolts are shown on the R.H. side.

A set of cross-head screwdrivers, pliers and hammers or mallets may also be essential. You will find that many bolts now have a "Torx" head. In case you have never seen a "Torx" head bolt, refer to Fig. 0.5. A socket set with special t "Torx" head inserts is used to slacken and tighten these screws. The size of the bolts are specified by the letter "T" before the across-flat size.

Circlip pliers may also be needed for certain operations. Two types of circlip pliers are available, one type for external circlips, one type for internal circlips. The ends of the pliers can either be straight or angled. Fig. 0.6 shows a view of the circlip pliers. Apart from the circlip pliers you may also need the pliers shown in Fig. 0.7, i.e. side cutters, combination pliers and water pump pliers.

Every part of the vehicle is tightened to a certain torque value and you will therefore need a torque wrench, which can be adjusted to a certain torque setting. In this connection we will also mention a graduated disc, shown in Fig. 0.7, as many parts of the vehicle must be angle-tightened after having been tightened to a specific torque. As some of the angles are not straight forward (for example 30 or 60 degrees), you will either have to estimate the angle or use the disc.

Finally you may consider the tool equipment shown in Fig. 0.8, shown on the next page, which will be necessary from time to time, mainly if you intend to carry out most maintenance and repair jobs yourself.


Fig. 0.6 – Circlip pliers are shown in the upper view. The type shown is suitable for outside circlips. The lower view shows a pair ofpointed pliers.

0.7. Before you start

Before you carry out any operations on your vehicle it may be of advantage to read the following notes to prevent injuries and damage to the vehicle:

• Never carry out operations underneath the vehicle when the front or rear is only supported on the jack. Always place chassis stands in position (refer to next section). If no chassis stands are available and if the wheels are removed place one wheel on top of the other one and place them under the side of the vehicle where you are working. If the jack fails the vehicle will drop onto the two wheels, preventing injury.

• Never slacken or tighten the axle shaft nuts or wheel bolts when the vehicle in resting on chassis stands.

• Never open the cooling system when the engine is hot. Sometimes it may, however, be necessary. In this case place a thick rag around the cap and open it very slowly until all steam has been released.

• Never allow brake fluid or anti-freeze to come in contact with painted areas.

• Never inhale brake shoe or brake pad dust. If compressed air is available, blow off the dust whilst turning the head away. A mask should be worn for reasons of safety.

• Remove oil or grease patches from the floor before you or other people slip on it.

• Do not work on the vehicle wearing a shirt with long sleeves. Rings and watches should be removed before carrying out any work.

• If possible never work by yourself. If unavoidable ask a friend or a member of the family to have a quick look to check that's everything is OK.

• Never hurry up your work. Many wheel bolts have been left untightened to get the vehicle quickly back on the road.

• Never smoke near the vehicle or allow persons with a cigarette near you. A fire extinguisher should be handy, just in case.

• Never place a hand lamp directly onto the engine to obtain a better view. Even though that the metal cage will avoid direct heat it is far better if you attach such a lamp to the open engine bonnet.

• Never drain the engine oil when the engine is hot. Drained engine oil must be disposed of in accordance with local regulation.
