Puddles on the garage floor or drive, or obvious wetness under the bonnet or underneath the car, suggest a leak that needs Investigating. It can sometimes be difficult to decide where the leak is coming from, especially if the engine bay is very dirty already. Leaking oil or fluid can also be blown rearwards by the passage of air under the car, giving a false impression of where the problem lies.
A
Warning: Most automotive oils and fluids aro poisonous. Wash them off skin, and change out of contaminated clothing, without delay.
Identifying leaks
The smell of 0 fluid leaking from the car may provide a clue to what's leaking. Some fluids are distinctively coloured. It may help to clean the car carefully and to park It over some clean paper overnight as an aid to locating the source of the leak. Remember that some leaks may only occur while the engine is running.
Sump oil
Engine oil may leak from the drain plug...
Antifreeze
Leaking antifreeze often leaves a crystalline oeposit like this.
Oil from filter
A leak occurring at a wheel Is almost certainly brake fluid.
Gearbox oil
Gearbox oil can leak from the seals at the inboard ends of the drivoshafts.
Power steering fluid
Power steering fluid may leak from the pipe connectors on the steering rack.
When ail else falls, you may llnd yourself having to get a tow home - or of course you may be helping somebody else. Long-distance recovery should only be done by a garage or breakdown service. For shorter distances. OIY towing using another car is easy enough, but observe the following points: • Use a proper tow-rope - they are not expensive. The vehicle being towed must display an ON TOW sign in its rear window. • Always turn the Ignition key to the ON position when the vehicle is being towed, so that the steering lock is released, and that the direction indicator and brake lights will work. • Only attach the tow-rope to the towing eyes provided.
• Before being towed, release the handbrake and select neutral on the transmission. • Note that greater-then-usual pedal pressure will be required to operate the brakes, since the vacuum servo unit is only operational with the engine running. • On models with power steering, greater-than-usual steering effort will also be required. • The driver of the car being towed must keep the tow-rope taut at all times to avoid snatching. • Make sure that both drivers know the route before setting off. • Only dnve at moderate speeds and keep the distance towed to a minimum. Drive smoothly and allow plenty of time for slowing down at junctions.
Towing
• On models with automatic transmission, special precautions apply(see Chapter 7B. Section 1). If In doubt, do not tow, or transmission damage may result. • The front towing eye is supplied as part of the tool kit stored in the luggage compart-ment. To fit the eye pnse out the plastic cover from the front or rear bumper using a screwdriver, then screw the eye onto the threaded pin as tightly as possible.

Warning: To prevent damage to the catalytic converter, e vehicle must not be push'started, or started by towing, when the engine is at operating temperature. Use jump leads (see Jump starting).

Choosing your engine oil
Engines need oil. not only to lubricate moving parts and minimise wear, but also to maximise power output and to Improve fuel economy. By introducing a simplified and improved range of engine oils. Duckhams has taken away the confusion and made it easier for you lo choose the right oil for your engine.
HOW ENGINE OIL WORKS
• Beating friction Without oil. the moving surfaces inside your engine will rub together, heat up and melt, quickly causing the engine to seize. Engine oil creates a film which separates these moving parts, preventing wear and heat build-up.
• Cooling hot-spots Temperatures Inside the engine can exceed 1000°
C.
The engine oil circulates and acts as a coolant, transferring heat from the hot-spots to the sump.
• Cleaning the engine internally Good quality engine oils clean the Inside of your engine, collecting and dispersing combustion deposits and controlling them until they are trapped by the oil niter or flushed out at oil change.
OIL CARE - FOLLOW THE CODE To handle and dispose of used engine oil safety, always: • Avoid skin contact with used engine oil. Repeated or prolonged contact can be harmful. • Dispose of used oil and empty packs In a responsible manner In an authorised disposal site. tti Call 0800 663366 to find qIqq f £ the one nearest to you. Never tip oil down drains or onto the ground.
DUCKHAMS ENGINE OILS For the driver who demands a premium quality oil for complete reassurance, we recommend synthetic formula Duckhama QXR Premium Engine Oils. For the driver who requires a straight-forward quality engine oil, we recommend Duckhams Hypergrade Engine Ote.

21 Engine management system check

A


Warning: Voltages produced by an electronic ignition system are considerably higher than those produced by conventional ignition systems. Extreme care must be taken when working on the system with the Ignition switched on. Persons with surgically-Implanted cardiac pacemaker devices should keep well clear of the ignition circuits, components and test oquipment. 1 The ignition system components should be checked for damage or deterioration as follows.
General component check 2 The spark plug (HT) leads should be checked whenever new spark plugs are fitted. 3 Pull the leads from the plugs by gripping
the end
fitting, not the lead, otherwise the lead connection may be fractured.
Ensure that the leads are i numbered before removing i them, to avoid confusion when refitting
4 Check Inside the end fitting for signs of corrosion, which will look like a white crusty powder. Push the end fitting back onto the spark plug, ensuring that it is a tight fit on the plug. if not, remove the lead again and use pliers to carefully crimp the metal connector inside the end fitting until it fits securely on the
end
of the spark plug. 5 Using a clean rag, wipe Ihe emlre length of the lead to remove any built-up dirt and grease. Once the lead is clean, check for bums, cracks and other damage. Do not bend the lead excessively, nor pull the lead lengthways - the conductor inside might break. 6 Disconnect the other end of the lead from the ignition coll. Again, pull only on the end fitting. Check for corrosion and a tight fit in the
same
manner as the spark plug end. Refit the bad securely on completion. 7 Check the remaining leads one at a time, in
ihe same
way. 8 if new spark plug (HT) leads are required, purchase a set for your specific car and engine. 9 Even with the ignition system In first-class condition, some engines may still occasionally experience poor starting attributable to damp ignition components. To disperse moisture, a water-dispersant aerosol should be liberally
Ignition timing -
check
and adjustment 10 Check the ignition timing as described In Chapter 58.
1 This check is part of the manufacturer's maintenance schedule, and Involves testing Ihe engine management system using special dedicated test equipment. Such testing will allow the test equipment to read any fault codes stored in the electronic control unit memory. 2 Unless a fault is suspected, this test te not essential, although it should be noted that it is recommended by the manufacturers. 3 If access to suitable test equipment is not possible, make a thorough check of all ignition, fuel and emission control system components, hoses, and wiring, for security and obvious signs of damage. Further details of the fuet system, emission control system and ignition system can be .found In the relevant parts of Chapters 4 and 5.
22 Hinge and lock lubrication %
1
1 Lubricate the hinges of the bonnet, doors and tailgate with a light general-purpose oil. Similarly, lubricate ail latches, locks and lock strikers. At the same time, check the security and operation of all the locks, adjusting them If necessary (see Chapter 11). 2 Lightly lubricate the bonnet release mechanism and cable with a suitable grease.
23 Headlight beam adjustment % & ^
1 Accurate adjustment of the headlight beam is only possible using optical beem-setting equipment, and this work should therefore be carried out by a Fiat dealer or service station with the necessary facilities. In an emergency, however, the following procedure will provide an acceptable light pattern. 2 Position the car on a level surface with tyres correctly inflated, approximately 10 metres in front of. and at right-angles to, a wall or garage door, 3 Draw a horizontal line on the wall or door at headlamp centre height. Draw a vertical line corresponding to the centre line of the car, then measure off a point either side of this, on the horizontal line, corresponding with the headlamp centres. 4 Switch on the main beam and check that the areas of maximum illumination coincide with the headlamp centre marfcs on Ihe wall, if not. turn the adjustment screw located on the upper inside edge of the headlight unit to adjust the beam laterally, and the adjustment screw located on the upper outside edge of the headlight unit to adjust the beam
vertically. On models with electric headlight adjustment, make sure that it is set at its basic setting before making the adjustment.
24 Road test
Instruments and electrical equipment 1 Check the operation of all Instruments and electrical equipment. 2 Make sure that all instruments read correctly, and switch on all electrical equipment in turn, to check that it functions properly.
Steering and suspension 3 Check for any abnormalities in the steering, suspension, handling or road feel. 4 Drive the vehicle, and check that there are no unusual vibrations or noises. 5 Check that the steering feels positive, with no excessive sloppiness, or roughness, and check for any suspension noises when cornering and driving over bumps.
Drivetrain 6 Check the performance of the engine, clutch (where applicable), transmission and driveshafts. 7 Listen for any unusual noises from the engine, clutch and gearbox/transmission. 8 Make sure that the engine runs smoothly when Idling, and that there Is no hesitation when accelerating. 9 Check that, where applicable, the clutch action Is smooth and progressive, that the drive is taken up smoothly, and that the pedal travel is not excessive. Also listen for any noises when the clutch pedal is depressed. 10 On manual gearbox models, check that all gears can be engaged smoothly without noise, and that the gear lever action is not abnormally vsgue or notchy. 11 On automatic transmission models, check that all Ihe gear positions can be selected with the vehicle at rest, if any problems are found, they should be referred to a Flat dealer. 12 Listen for a metallic clicking sound from the front of the vehicle, as the vehicle is driven slowly in a circle with the steering on full-lock. Carry out this check in both directions. If a clicking noise is heard, this Indicates wear in a drtveshaft joint, In which case renew the joint if necessary.
Check the braking system 13 Make sure that the vehicle does not pull to one side when braking, and that the wheels do not lock prematurely when braking hard. 14 Check that there is no vibration through the steering when braking. 15 Check that the handbrake operates correctly without excessive movement of the lever, and that It holds the vehicle stationary on a slope.

The transmission is contained In a cast-aluminium alloy casing bolted to the engine's left-hand end, and consists of the gearbox end final drive differential, Drive Is transmitted from the crankshaft via the clutch to the Input shaft, which has a spiined extension to accept the clutch friction
plate, and rotates in roller bearings at its right-hand end and ball bearings at its left-hand end (on 6-speed versions the left-hand extension rotates In a roller bearing). From the input shaft, drive is transmitted to tho output shaft, which rotates In roller bearings at Its right-hand end. and ball bearings at its left* hand end (on 6-speed versions the left-hand extension rotates in ball bearings). From the output shaft, the drive is transmitted to the differential crownwheel, which rotates with the differential case and gears in taper roller bearings, thus driving the sun gears and
driveshafts. The rotation of the differential gears on their shaft allows the inner roadwheel to rotate at a slower speed than the outer roadwheel when the car is cornering. The Input and output shaftB are arranged side by side, parallel to the crankshaft and driveshafts, so that their gear pinion teeth are In constant mesh. In the neutral position, the relevant input shaft and output shaft gear pinions rotate freely, so that drive cannot be transmitted to the output shaft and crownwheel.

1 General information
Power is transmitted from the differential to
Ihe
roadwheels by the driveshafts. via inboard and outboard constant velocity (CV) joints (we illustrations). An intermediate drive shaft, with its own support bearing is fitted between the gearbox output and right-hand drive shafts on turbo desei models (see Illustration overleaf). This layout has the effect of equalising driveshaft angles at sll suspension positions and reduces tfveshaft flexing, which improves directional stability, particularly under acceleration. The outer Rzeppa type CV joints allow smooth transmission of drive to the wheels at all steering and suspension angles. Drive Is transmitted by means of a number of radially static steel balls that run In grooves between
the two halves of the joint. The type of inboard CV joint fitted is model dependant. Those fitted to all except the turbo diesel models are of the plunge-cup type; drive is transmitted across the joint by means of three rollers, mounted on the driveshaft in a tripod arrangement, that are radially static but are free to slide in the grooved plunge cup.
The inboard CV joints fitted to turbo diesel models are of the Rzeppa type, similar to those at the outboard end of the driveshaft. On the right-hand driveshafl, the joint is bolted directly to the end of the intermediate driveshaft flange. On the left-hand driveshaft, the joint is bolted to the transmission output shaft flange.
