Safety first! 0.5
Working on your ear can be dangerous. This page shows just some of the potential risks and hazards, with the aim of creating a safety-conscious attitude.
General hazards
Scalding • Don't remove the radiator or expansion tank cap while the engine is hot. • Engine oil, automatic transmission fluid or power steering fluid may also be dangerously hot if the engine has recently been running.
Burning • Beware of burns from the exhau3t system and from any part of the engine. Brake discs and drums can also be extremely hot immediately after use.
Crushing • When working under or near a raised vehicle. ~ always supplement the ' ' -jack with axle stands, or use ... drive-on i'j ramps. kr Never venture ™ under
a
car
vv/j/ch
Is only supported by a jack. • Take card if loosening or tightening high-torque nuts when the vehicle is on stands. Initial loosening and final tightening should be done with the wheels on the ground.
Fire • Fuel Is highly flammable; fuel vapour is explosive. • Don't (et fuel spill onto a hot engine. • Do not smoke or allow naked lights (including pilot lights) anywhere near a vehicle being worked on. Also beware of creating sparks (electrically or by use of toots). • Fuel vapour is heavier than air, so don't work on the fuel system with the vehicle over an inspection pit. • Another cause of fire is an electrical overload or short-circuit. Take care when repainng or modifying the vehicle wiring. • Keep a fire extinguisher handy, of a type suitable for use on fuel and electrical fires.
Electric shock x ^ ^ ? , • Ignition HT _ " voltage can be ^ dangerous, ~ especially to > people with heart problems or a pacemaker. Don't work on or near the f^ ignition system with fT") the engine running or ' J ' J the Ignition switched on.
• Mains voltage is also dangerous. Make sure that any mains-operated equipment is correctly earthed. Mains power points should be protected by a residual current device (RCD) circuit breaker.
Fume or gas intoxication • Exhaust fumes are poisonous: they often contain carbon monoxide, which is rapidly fatal if inhaled. Never run the engine in a confined space such as a garage with the doors shut, • Fuel vapour is also poisonous, as are the vapours from some cleaning solvents and paint thinners.
Poisonous or irritant substances • Avoid skin contact with battery acid and with any fuel, fluid or lubricant, especially antifreeze, brake hydraulic fluid and Diesel fuel. Don't syphon them by mouth. If such a substance is swallowed or gets into the eyes, seek medical advice. « Prolonged contact with used engine oil can cause skin cancer. Wear gloves or use a barrier cream If necessary. Change out of oll-soaked clothes and do not keep oily rags in your pocket. • Air conditioning refrigerant forms a poisonous gas if exposed to a naked flame {including a cigarette). It can also cause skin burns on contact.
Asbestos • Asbestos dust can cause cancer if inhaled or swallowed. Asbestos may be found In gaskets and in brake and clutch linings. When dealing with soch components It is safest to assume that they contain asbestos.
Special hazards
Hydrofluoric acid • This extremely corrosive acid is formed when cerlam types of synthetic rubber, found In some O-rings, oil seals, fuel hoses etc. are exposed to temperatures above 400;C. The rubber changes into a charred or sticky substance containing the acid. Once formed, the acid remains dangerous for years, tfit gets onto the skin, it may be necessary to amputate the limb concerned. • When dealing with a vehicle which has suffered a fire, or with components salvaged from such a vehicle, wear protective gloves and discard them after use.
The battery • Batteries contain sulphuric acid, which attacks clothing, eyes and skin. Take care when topping-up or carrying the battery. • The hydrogen gas given off by the battery is highly explosive. Never cause a spark or allow a naked light nearby. Be careful when connecting and disconnecting battery chargers or jump leads.
Air bags • Air bags can cause injury if they go off accidentally. Take care when removing the steenng wheel and/or facia. Special storage instructions may apply.
Diesel injection equipment • Diesel injection pumps supply fuel at very high pressure. Take care when working on the fuel injectors and fuel pipes.

A


Warning: Never expose the hands, face or any otfterpart of the body to injector spray; the fuel can penetrate the skin with potentially fatal results.
Remember...
DO • Do use eye protection when using power tools, and when working under the vehicle. • Do wear gloves or use barrier cream to protect your hands when necessary. • Do get someone to check periodically that all is well when working alone on the vehicle. • Do keep loose clothing and long hair well out of the way of moving mechanical parts. • Do remove rings, wrtstwatch etc. before working on the vehicle - especially the electrical system, • Do ensure that any lifting or jacking equipment has a safe working load rating adequate for the job.
DON'T • Don't attempt to lift a heavy component which may be beyond your capability - get assistance. • Don't rush to finish a job. or take unverified short cuts. • Don't use ill-fitting toots which may slip and cause injury. • Don't leave tools or parts lying around where someone can trip over them. Mop up oil and fuel spills at once. • Don't allow children or pets to play In or near a vehicle being worked on.

Roadside repairs 0.9
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.

A


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).

Weekly checks 015
Automatic transmission fluid level
Before you start: • Park the vohicle on level ground, and apply the handbrake firmly. Let the engine idle, and select P or N.
Safety First! • The need for frequent topping-up indicates a leak, which should bo Investigated immediately.

I

Open the bonnet. Withdraw the trans-mission dipstick, and wipe it with a clean non-fluffy rag. Re-Insert the dipstick fully, withdraw it again and read the fluid level. II should be between (he two level marks. There are two sets of marks. Use the COOL marks if the transmission is cold (20" to 40°C) or the HOT marks if it Is hot (60" to 809C).

2

If topping up fs necessary, add the specified fluid via the dipstick tube, using a funnel with a fine mesh filter. Take great care nol to introduce dirt into the transmission.
Screen washer fluid level
Screenwash additives not only keep the wlnscreen clean during foul weather, they also prevent the washer system freezing kn cold weather • which is when you are likely to need it most. Don't top up using plain water as the screenwash will become too diluted, and will freeze during cold weather. On no account use coolant antifreeze In the washer system • this could discolour or damage paintwork.
3H
m

I

The screen washer fluid reservoir is located on the left-hand side of the engine compartment, next to the battery. Prise off the cap and pull out the telescopic filler.

2

When topping-up the reservoir, add a screenwash additive In the quantities recommended on the bottle. Use of a funnel wilt prevent spillage.
Wiper blades

1

Check the condition of the wiper blades; if they are cracked or show any signs of deterioration, or if the glass swept area is smeared, renew them. Wiper blades should be renewed annually. Don't forget to check the tailgate wiper as well.

2

To remove a wiper blade, pull the arm fully away from the screen until It locks. Swivel the blade through 90", press the locking tab with your fingers and slide the blade out of the arm's hooked end.

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.

be checked, and the condition of the brake disc itself can be fully examined on both sides. Refer to Chapter 9 for further Information. 4 If any pad's friction material is worn to the specified thickness or less, all four psds must tie renewed as a set. Refer to Chapter 9. 5 On completion refit the roadwheels and lower the car to the ground
6 Underbody sealant check
I
1 Jack up the front and rear of the car and support It securely on axle stands (see Jacking and vehicle support). Alternatively position the car over an inspection pit. 2 Check the underbody. wheel housings and side sills for rust and/or damage to the under-body sealant. If evident, repair as necessary.
7 Hose and fluid leak check ^
I
1 Visually Inspect the engine joint laces, gaskets and seals for any signs of water or oil leaks. Pay particular attention to the areas around the camshaft cover, cylinder head, oil (liter and sump joint faces. Bear in mind that.
A leak In the cooling system will usually show up as white or rust~coloured deposits on the area adjoining the leak
over a period of time, some very slight seepage from these areas is to be expected -what you are really looking for is any indication of a serious leak (see Haynes Hint). Should a leak be found, renew the offending gasket or oil seal by refemng to the appropriate Chapters in this manual. 2 Also check the security and condition of all the engine-related pipes and hoses. Ensure that all cable-ties or securing clips ore In place and In good condition, Clips which are broken or missing can lead to chafing of the hoses, pipes or wiring, which could cause more serious probioms In the luture. 3 Carefully check the radiator hoses and heater hoses along their entire length. Renew any hose which is cracked, swollen or deteriorated, Cracks will show up better if the hose is squeezed. Pay close attention to the hose clips that secure the hoses to the cooling system components. Hose clips can pinch and puncture hoses, resulting in cooling system leaks. 4 Inspect all 'he cooling system components {hoses. |olnt faces etc.) for leaks. A leak in the coolmg system will usually show up as white-or rust-coloured deposits on the area adjoining the leak. Where any problems of this nature are found on system components, renew the component or gaskel with reference to Chapter 3. 5 Where applicable, inspect the automatic transmission fluid cooler hoses for leaks or deterioration. 6 With the vehicle raised, inspect the fuel tank and filler neck for punctures, cracks and other damage. The connection between the filler neck and tank Is especially critical. Sometimes a rubber filler neck or connecting hose will leak due to loose retaining clamps or deten orated rubber. 7 Carefully check all rubber hoses and metal fuel lines leading away Irom the fuel tank. Check for loose connections, deteriorated hoses, crimped lines, and other damage. Pay particular attention to the vent pipes and hoses, which often loop up around the fitter neck and can become blocked or crimped. Follow the lines to the front of the vehicle, carefully inspecting them all the way. Renew damaged sections as necessary. 8 From within tne engine compartment,
check the security of all fuel hose attachments and pipe unions, and inspect the fuel hoses and vacuum hoses for kinks, chafing and deterioration. 9 Where applicable, check the condition of the power steering fluid hoses and pipes.
8 Exhaust system check fe
1 With the engine cold (at least an hour after the vehicle has been driven), check the complete exhaust system from the engine to the end of the tailpipe. The exhaust system is most easily checked with the vehicle raised on a hoist, or suitably supported on axle stands (see Jacking and vehicle support), so that the exhaust components are readily visible and accessible. 2 Check the exhaust pipes and connections for evidence of leaks, severe corrosion and damage. Make sure thai all brackets and mountings are in good condition, and that all relevant nuts and bolts are tight, Leakage at any of the Joints or in other parts of the system will usually show up as a black sooty stain in the vicinity of the leak. 3 Rattles and other noises can often bo traced to the exhaust system, especially the brackets and mountings. Try to move the pipes and silencers. If the components are able to come Into contact with the body or suspension parts, secure the system with new mountings Otherwise separate the joints {if possible) and twist the pipes as necessary to provide additional clearance.
9 Driveshaft gaiter check
9.1 Checking the condition of a driveshaft gaiter
1
1 With the vehicle raised and securely supported on stands (see Jacking and vehicle support), turn the steering onto full lock, then s'owly rotate the roadwheel. Inspect the condition of Ihe outer constant velocity (CV) joint rubber garters, squeezing the gaiters to open out the folds. Check for signs of cracking, splits or deterioration of the rubber, which may allow the grease to escape, and lead to water and grit entry into the joint. Also check the security and condition of the retaining clips. Repeat these checks on the Inner CV joints (see Illustration), If any damage or deterioration Is found, the gaiters should be renewed (see Chapter 8, Section 3). 2 At the same time, check the general condition of (he CV joints themselves by first holding (he driveshaft and attempting to rotate the wheel. Repeat this check by holding the inner joint and attempting to rotate the driveshaft. Any appreciable movement indicates wear in the joints. wear In the driveshaft splines, or a loose driveshaft retaining nut

16 Test the operation of the brake servo unit as follows. With the engine off, depress the footbrake four or five times to exhaust the vacuum. Hold the brake pedal depressed, then start the engine. As the engine starts.
there should be a noticeable give In the brake pedal as vacuum builds up. Allow the engine to run for at least tsvo minutes, and then switch it off. If the brake pedal is depressed now. it should be possible to detect a hiss
from the servo as the pedal is depressed. After about four or five applications, no further hissing should be heard, and the pedal shouto feel considerably harder.
