Introduction

Introduction to the Fiat Uno
The Fiat Uno is a well designed and constructed car having an excellent power-to-weight ratio. The car is very economical, but still offers good performance with excellent body interior space. Attractive features include the options available for four- or five-speeds or three- or five-door bodywork. All essential accessories, except a radio, are fitted as standard and a sunroof is optionally available. From the home mechanic's point of view all repair and servicing operations are straightforward without the need for special tools. Spare parts are immediately available at moderate cost.

Safety First!
Working on your car can be dangerous. This page shows just some of the potential risks and hazards, with the aim of creating a safety-conscious attitude. · 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.

0·5

Special hazards
Hydrofluoric acid
· This extremely corrosive acid is formed when certain types of synthetic rubber, found in some O-rings, oil seals, fuel hoses etc, are exposed to temperatures above 4000C. The rubber changes into a charred or sticky substance containing the acid. Once formed, the acid remains dangerous for years. If it 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.

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.

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.

Burning
· Beware of burns from the exhaust system and from any part of the engine. Brake discs and drums can also be extremely hot immediately 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.

Crushing
· When working under or near a raised vehicle, always supplement the jack with axle stands, or use drive-on ramps. Never venture under a car which is only supported by a jack. · Take care if loosening or tightening hightorque nuts when the vehicle is on stands. Initial loosening and final tightening should be done with the wheels on the ground.

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 oilsoaked 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.

Air bags
· Air bags can cause injury if they go off accidentally. Take care when removing the steering 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. Warning: Never expose the hands, face or any other part of the body to injector spray; the fuel can penetrate the skin with potentially fatal results.

Fire
· Fuel is highly flammable; fuel vapour is explosive. · Don't let 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 tools). · 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 repairing or modifying the vehicle wiring. · Keep a fire extinguisher handy, of a type suitable for use on fuel and electrical fires.

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 such components it is safest to assume that they contain asbestos.

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, wristwatch 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.

A few tips
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 tools 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.

Electric shock
· Ignition HT voltage can be dangerous, especially to people with heart problems or a pacemaker. Don't work on or near the ignition system with the engine running or the ignition switched on.

Roadside Repairs
Jump starting will get you out of trouble, but you must correct whatever made the battery go flat in the first place. There are three possibilities: The battery has been drained by repeated attempts to start, or by leaving the lights on. The charging system is not working properly (alternator drivebelt slack or broken, alternator wiring fault or alternator itself faulty). The battery itself is at fault (electrolyte low, or battery worn out).

Jump Booster battery (jump) starting starting
When jump-starting a car using a booster battery, observe the following precautions: 4 Before connecting the booster battery, make sure that the ignition is switched off. 4 Ensure that all electrical equipment (lights, heater, wipers, etc) is switched off. 4 Make sure that the booster battery is the same voltage as the discharged one in the vehicle. 4 If the battery is being jump-started from the battery in another vehicle, the two vehcles MUST NOT TOUCH each other. 4 Make sure that the transmission is in neutral (or PARK, in the case of automatic transmission).

Roadside Repairs

Jacking, towing and wheel changing
To avoid repetition, the procedure for raising the vehicle, in order to carry out work under it, is not included before each relevant operation described in this Manual. It is to be preferred, and it is certainly recommended, that the vehicle is positioned over an inspection pit or raised on a lift. Where these facilities are not available, use ramps or jack up the vehicle strictly in accordance with the following guide. Once the vehicle is raised, supplement the jack with axle stands. To raise the front end with a garage jack, locate the jack under the transmission lower mounting, just below and slightly to the rear of the transmission oil drain plug. Protect the mounting by placing a block of wood between the jack head and the mounting. To raise the rear of the car, the jack should be placed under the spare wheel housing as far to the rear as possible. Place a wooden bearer between the jack head and the housing. ignition key to MAR to retain the steering in the unlocked position.

Wheel changing
With the car on firm level ground, apply the handbrake fully. Remove the hub cap or wheel trim, if fitted. Release, but do not remove, the bolts. Chock the front and rear of the opposite roadwheel and then raise the car using the sill jack supplied with the car if it is being done at the roadside. Alternatively use a workshop jack supplemented with axle stands. Remove the wheel bolts, change the wheel and screw in the bolts finger tight. It is recommended that the bolt threads are smeared with multi-purpose grease. Lower the car, remove the jack and tighten the wheel bolts to the specified torque. Refit any wheel trim that was removed.

Jacking
The jack supplied with the car should only be used to change a wheel. Do not use this jack when overhaul or repair work is being carried out; employ a hydraulic or screw jack and supplement it with axle stands. Jacking points are located under the sills for use with the jack supplied.

Towing
When being towed, use the left-hand front towing eye. When towing another vehicle, use the rear towing eye adjacent to the exhaust tailpipe. When being towed, remember that the brake pedal will require heavier pressure due to lack of servo assistance. Always turn the

Identifying leaks
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. Warning: Most automotive oils and fluids are poisonous. Wash them off skin, and change out of contaminated clothing, without delay. The smell of a 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 and to park it over some clean paper as an aid to locating the source of the leak. Remember that some leaks may only occur while the engine is running.

Sump oil

Oil from filter

Gearbox oil

Engine oil may leak from the drain plug...

...or from the base of the oil filter.

Gearbox oil can leak from the seals at the inboard ends of the driveshafts.

Antifreeze

Brake fluid

Power steering fluid

Leaking antifreeze often leaves a crystalline deposit like this.

A leak occurring at a wheel is almost certainly brake fluid.

Power steering fluid may leak from the pipe connectors on the steering rack.

Routine maintenance

Maintenance is essential for ensuring safety and desirable for the purpose of getting the best in terms of performance and economy from the car. Over the years the need for periodic lubrication has been greatly reduced if not totally eliminated. This has unfortunately tended to lead some owners to think that because no such action is required the items either no longer exist or will last forever. This is certainly not the case; it is essential to carry out regular visual examinations as comprehensively as possible in order to spot any possible defects at an early stage before they develop into major and expensive repairs. For information applicable to later models, see Supplement.

The camshaft bearings are fed from a drilling from the main oil gallery. The cams and tappets are lubricated by oil mist from outlets in the camshaft bearings. 15 The cylinder walls, pistons and gudgeon pins are lubricated by oil splashed up by the crankshaft webs. An oil pressure warning light is fitted to indicate when the pressure is too low.
