No liability can be accepted by the authors or publishers for loss, damage or injury caused by any errors in. or omiSSIons from, the information g ven. Acknowledgements Thanks are due to Champion Spark Plug who supplied spark plug Information. Certain Illustra Ions are the copynght 0 Crtroen Cars Ltd, and are used with their permiSSion. Thanks are also due to Sykes-Plckavant. who provided many of he workshop tools. and all those at Sparkford who assisted In the producuon of IS manual The Citroen IV< was Introduced In the UK In July 1987 (having being launched in France he previous September), the imtial versions being three-door Hatchbacks. The five-door version was introduced in April 1988. All engines are denved from the well-proven TU series engines which have appeared in many Peugeot and Citroen vehIcles. The engine IS of four-cylinder overhead camshaft design. mounted transversely. With the transmission mounted on the left-hand Side. All models have a four- or five-speed manual ransmisslon In early 1989. a 1.4 litre (1360 ccl Diesel engine was added to the range. In September 1991. the ·second-generatlon" AX was introduced, with revised interior and extenor styling. A 1527 cc DIesel engine was introduced In July 1994 - however, at the time of Writing, only limited technical information was available for this engine. All models have fUlly-independent front and rear suspension. The rear suspension incorporates torsion bars and trading arms. A Wide range of standard and optional equipment IS available Within he IV< range 0 SUit most tastes. Including central locking and electric Windows. An anti-Ioc bra Ing system and air conditioning system are available as options on certain models. ProVided that regular seMclng IS earned out In accordance With the manufacturer's recommendations. the Citroen IV< should prove reliable and very economical. The engine compartment IS well-designed. and most of he items reqUiring frequent attention are easily accessible About this manual The aim of thiS manual IS to help you get he best value from your vehicle. It can do so In several ways It can help you deCide what work must be done (even should you choose to get It done by a garage). It will also provIde Information on routine maintenance and servIcing. and give a logical course of action and diagnosis when random faults occur. However. it IS hoped that you will use he manual by tackling the work yourself. On simpler Jobs It may even be qUicker than booking he car Into a garage and gOing here tWice. to leave and collect It. Perhaps most Important. a 10 of money can be saved by avoiding the costs a garage must charge to cover Its labour and overheads. The manual has draWIngs and descnptlons to show the function of the various components so that their layout can be understood. Tasks are described and photographed In a clear step-by-step sequence. References to the "left" or "rlgh of he vehicle are in the sense of a person In the driving seat, facing orwards.

0·6 Spare Part s are Spare parts are available Irom many sources; for example, Citroen garages, other garages and accessory shops, and motor lactors, Our advice regarding spare part sources IS as follows. Officially-appointed Citroen garages - This IS the bes source for parts which are peculiar to your car, and are not generally available (eg compie e cyllnder heads, Internal gearbox components, badges, Interaor tram etc). It IS also the only place at which you should buy pans If the vehicle IS stili under warranty To be sure of obtaining the correct parts, it Will be necessary to give the storeman your car's vehicle Identification number, and if possible, take he old parts along for positive Identification. Many parts are available under a factory exchange scheme· any parts returned should always be clean It obviously makes good sense 0 go straight to the specialists on your car for this type 01 part, as they are best equipped 0 supply you. Other garages and accessory shops - These are often very good places to buy matenals and components needed lor the maintenance of your car (eg 011 filters, spark plugs/glow plugs. bulbs, dnvebelts. oils and greases. touch-up pain, Iller paste, etc) They also sell general acceSSOries, usually have convenient opening hours, charge lower prices, and can often be ound no far rom home. Motor factors - Good factors Will stock all the more Important components which wear out comparatively qUickly (eg e haust systems, brake pads, seals and hydraulic parts, clutch components, bearing shells, pistons, valves etc). Motor factors will often provide new or reconditioned components on a part-exchange basIs· hiS can save a conSiderable amount of money. Vehicle identification numbers Modifications are a continuing and un publiCised process in vehicle manufacture, QUIte apart rom malor model changes Spare parts lists are compiled upon a numeracal baSIS, he indiVidual vehicle identlflcalion numbers being essential 0 correct identification of the component concerned When ordering spare parts, always give as much Informa Ion as pOSSible. Quote th car model. year of manufacture. body and engine numbers, as appropriate (see illustrations) The Vehicle IdentificatIOn Number (VIN) plate IS located on the nght-hand front wheel arch/wing valance on models manufactured up to June 1988 - on models manufactured from June 1988 onwards It IS on the Ie -hand Side or attached to the crossmember at he front of the engine compartment. The plate can be Viewed once the bonnet IS open. The plate carnes the VIN and vehIcle weight Informalion. The chaSSIS number IS stamped In a he body. along the lOP Inner edge 01 the right· hand wing. and can be viewed With the bonne open (see illustration). On some models. the chaSSIS number may also be etched Into the Windscreen and Window glass. The engme number IS situated on the Ie - hand end of the front face of the cylinder block On models With an aluminium cylinder block. the number IS stamped on a plate which IS riveted to the block (see Illustration) on models With a cast-Iron cylinder block. the number is stamped on a machined surface on the cylinder block. at the flywheel end. The first part of the engine number gIves the engine code - eg "H1A The pamt code IS stamped onto the rlght- hand ron suspensIon urrel.

Rear view mirrors must be secure, Intact, and capable 01 being adJusted

Steering and suspension o Have your assistant tum the steering wheel from Side to Side slightly, up to the point where the steering gear Just beginS to transmrt this movement to the roadwheels. Check for excessive free play between the steenng wheel and the steenng gear. Indicating wear or insecunty of the steering column joints, he column-to-steerlng gear coupling, or the steering gear itself. _ Have your assistant turn the steering wheel more vigorously In each direction, so that the roadwheels Just begin to turn As thiS IS done, examine all the steering JOints, linkages, fittings and attachments. Renew any componen that shows signs of wear or damage On vehicles With power steering, check the security and condition of he steering pump, dnvebelt and hoses. Check hat the vehicle IS standing level. and a apprOXimately the correc ride height. Shock absorbers C Depress each corner of the vehicle in turn then release it. The vehicle should nse and then settle In Its norma! position. If the vehicle continues to rise and fall. the shock absorber is defective. A shock absorber which has seized will also cause the vehicle to fail. '= Inspec both front brake flexible hoses for cracks or deterroratlon of the rubber. Turn the steering from lock to lock, and ensure hat the hoses do not contact the wheel, tyre, or any part of the steering or suspension mechanism. With the brake pedal firmly depressed. check the hoses for bulges or leaks under pressure. :I The flUid reservoir must be secure and the tkJld level must be between he upper (A) and lower (B) markings.

Look for corroSion, chafing or insecurr y of the pipes, and for signs a bUlging under pressure, chafmg, splits or deterioration of the flexible hoses J Look for Signs of flUid leaks at the brake calipers or on the brake backplates Repair or renew leaking components. Slowly spin each wheel, while your assistant depresses and releases the footbrake. Ensure thaI each brake IS operating and does not bind when the pedal IS released. Carry out all the above checks at the a her tront wheel and then at both rear wheels. II excess free play is suspected at a component pivot pOint, thiS can be confirmed by uSing a large screwdnver or Similar tool and levering between the mounting and the component attachment ThiS will confirm whether the wear IS 10 the PiVOt bush, Its retaining bolt, or 10 the mountrng itself (the bolt holes can often become elongated). Front and rear suspension and wheel bearings 'j Starting at the fron right-hand side, grasp the roadwheel at he 3 o'clock and 9 o'clock positions and shake i vigorously. Check lor Iree play or Insecunty at the wheel beanngs, suspension balfjornts. or suspension mount- Ings, pivotS and attachments. cJ Now grasp the wheel at the 12 o'clock and 6 o'clock poslt:JOns and repeat the prevIous inspection. Spin the wheel, and check for roughness or tightness of the front wheel bearing Springs and shock absorbers - Examine the suspension struts (when applicable) or senous lIU1d leakage, corrosion. or damage 0 the casing Also check the secull1y of the mounting pornts If COil spnngs are fitted, check that he spnng ends locate In their seats. and that the sprmg is not corroded, cracked or broken If leaT spnngs are filled. check thaI all leaves are ,n act. hat the axle is securely attached a each spring and that there IS no deterroratlon ot the spring eye mountings, bushes and shackles, Exhaust system Start the englOe.

Diesel models ::: The only emission test applicable to Diesel engll1es IS the measunng of e haust smoke denSity The test Involves accelerating the engtne several Imes to I s maximum unloaded speed Note: It IS of the utmost importance thaI the engine timing belt is In good condition before the lest IS earned out .., ExcesSive smoke can be caused by a dirty alt cleaner elemenl Otherwise, profesSional adVice may be needed to Ind the cause. HC emissions ~ With the CO emiSSions within limits, HC emiSSions must be no more han 1200 ppm (parts per million). If he vehicle falls thiS tes1 at Idle, It can be re-tested at around 2000 rpm If the HC level IS then 1200 ppm or less, thiS counts as a pass :::::; ExcesSive HC emissions can be caused by 011 betng burn • but they are more likely 0 be due to unbumt fuel. CO emissions (mixture) ...J At the time or wntlng, the maximum CO level at Idle is 3.5% for vehicles first used after August 1986 and 4 5% for older vehicles. From January 1996 a much tlgh er limit (around 0.5%1 applies 0 catalyst-eqUipped vehicles firs used from August 1992. If the CO level canna be reduced far enough to pass the est (and the fuel and ignition systems are otherwise in good condition) then he carbure or IS badly worn, or there IS some problem In the fuel Il1Jectlon system or catalytic converter (as applicable). for smoke emissions from the exhaust ailplpe If the Idle speed IS obViously much 00 high. or I dense blue or clearly-vIsible black smoke comes from the tailpipe for more han 5 seconds, the vehicle Will fail. As a rule of thumb, blue smoke Signifies 011 being burnt (engine wear) while black smoke signifies unburnt fuel (dirty air cleaner element. or other carburettor or fuel system fault). o An exhaust gas analyser capable of measuring carbon monoxide (CO) and hydrocarbons (HC) is now needed. If such an Instrument cannot be hired or borrowed, a local garage may agree to perform the check or a small fee. Petrol models '--.J Have he engine a normal operating temperature. and make sure hat It is in good tune (ignition system In good order, air flI er elemen clean. etc).

Connect one jump lead between the positive (+) terminals of the two batteries. Connect the other jump lead first to the negative (-) terminal of the booster battery, and then to a good earthing point on the vehicle to be started, such as a bolt or bracket on the engine block, at least 45 cm (18 in) from the battery if possible (see illustration). Make sure that the jump leads will not come into contact with the fan, drivebelts or other moving parts of the engine. Start the engine using the booster battery, and run it at idle speed. Switch on the lights, rear window demister and heater blower motor, then disconnect the jump leads in the reverse order of connection. Turn off the lights, etc. ~ """" 18in MIN DISCHARGED BATTERY Jump start lead connections for negative- earth vehicles - connect leads in order shown Radio/cassette unit anti-theft system - precaution On later models, the radio/cassette unit fitted as standard equipment by Citroen is equipped with a built-in security code, to deter thieves. If the power source to the unit is cut, the anti-theft system will activate. Even if the power source is immediately reconnected, the radio/cassette unit will not function until the correct security code has been entered. Therefore, if you do not know the correct security code for the radio/cassette unit, do not disconnect the battery negative terminal of the battery, or remove the radio/cassette unit from the vehicle. To enter the correct security code, follow the instructions provided with the radio/cassette player handbook. If an incorrect code is entered, the unit will become locked, and cannot be operated.
