Start every time this New Year

It's easy to be blasé about your car's battery. For years it works fine and then suddenly one frosty morning your car won't start. Of course, you can call a breakdown service but with the RAC and AA reporting 40,000 calls in just one day this week, how long will you have to wait to be rescued? Battery failure is the number one reason motorists call a breakdown service. And it is just one of many common faults that are caused by a lack of basic maintenance.

With the help of a Haynes Owners Workshop Manual you can avoid being stranded and save yourself money. For example, often the first sign of battery trouble is that the engine is reluctant to start when cold, with the starter motor turning more slowly than usual. That's the time to get the battery checked and replace it if necessary - a Haynes Owners Manual gives you step-by-step instructions.

There are many other simple DIY maintenance tasks detailed in Haynes Manuals - replacing wiper blades and bulbs, checking the tyres, monitoring engine oil and coolant levels and so on. With the average labour rate at a UK dealer now £85 per hour, a Haynes Manual costing under £20 could save you a fortune - a good deal in these financially challenging times!

Of course, having your vehicle serviced regularly is important but it does not stop there. Over the years manufacturers have greatly increased the service intervals, therefore there is an even greater need to carry out safety and maintenance checks in between these long periods. Carrying out such checks will help avoid unwelcome bills and minimise the expense or the inconvenience of a breakdown Although many car owners believe that modern cars are too complicated for them to work on, this is not so. Routine tasks can be done by anybody - if they know what they are doing.

Haynes, the world-leading publisher of automotive repair manuals, is renowned for teaching millions of car owners how to carry out routine maintenance and repairs. The manuals provide authoritative and accurate step-by-step information for both basic and more complex tasks. Over the next few months, our mission is to give you a greater understanding of your car and provide you with essential tips, advice and tasks that will aid trouble-free motoring. For example: how to check tyres and engine fluids, replace wiper blades, light bulbs and spark plugs, how to conduct a pre-MOT test check and what to do before taking your car on holiday or abroad.

Let's start with that flat battery and how to replace it.

Modern car electrical systems put big demands on the battery. Sometimes a battery will fail with no warning, but usually the first sign of trouble is that the engine is reluctant to start when cold, with the starter motor turning more slowly than usual. This is then followed by a failure to start at all.

There are three main reasons for a battery to be flat. One is old age, in which case fitting a new battery will cure the problem. The second is leaving the lights on (or even the radio or alarm, if parked for a long time); generally a jump-start will put things right - although the life of the battery will be shorter following a complete discharge. The third is a problem with the charging system; fitting a new battery won't cure that.

A Haynes Service and Repair Manual gives simple tests so that you can identify the reason for your flat battery.

Replacing a Battery  

You'll need a new battery of the correct size and capacity to fit your car. If you plan to use it straight away, it needs to be charged - ask when you buy it. Buy some copper grease or special battery terminal corrosion protector spray too.

Warning:Batteries contain sulphuric acid, which is poisonous and causes burns; they give off hydrogen gas, which is explosive when mixed with air; when charged they contain enough electrical energy to cause burns or fires if short-circuited. Follow all precautions specified by the manufacturer.

Make sure you know the radio code, because you'll need it after the new battery has been connected. Or on some cars you can use a 'memory saver' battery plugged into the cigarette lighter socket.

1. Disconnect the electrical leads from the old battery, negative (earth) first (look for a '-' sign near the battery terminal). Undo the fixing clamp nut or bolt - details vary for each car - and lift out the battery. Be careful not to drop it, and keep it upright to avoid acid spillage.
2. Fit the new battery, secure it with the clamp and connect the electrical leads, negative (earth) last. Protect the terminals against corrosion by smearing them with copper grease or using an anti-corrosion spray.
3. Check that the negative (earth) lead connection to the car body is clean and tight. Unbolt it and clean it with a wire brush or abrasive paper, if necessary.
