Spark Plugs

Spark plugs are simply insulated plugs that are screwed into the engine’s cylinder head to deliver the spark that ignites the mixture of air and fuel in the combustion chamber which in turn helps to start your vehicle. Spark plugs also transfer heat away from the combustion chamber. The spark plug sits at the top of the cylinder head. The piston first travels down the cylinder, drawing in a mixture of fuel and air. The piston then goes back up toward the spark plug, compressing the mixture. At the very last second, when the piston is at its fullest reach or top dead centre (TDC), the spark plug sparks and ignites the mixture. The piston is forced back down to create power for the vehicle, then pushed back up again to clear out the exhaust. At that point, the process starts all over again. A four-cylinder car will have four spark plugs; a six-cylinder car will have six and so on.  A spark plug provides the spark that burns the fuel, its secondary role is to disperse heat. A spark plug’s ability to transfer heat to the cars cooling system is based on the length of the insulator nose and the materials used for the centre electrode and the insulator. Standard spark plugs in modern engines have a copper centre electrode core surrounded by a nickel alloy, which you can see at the tip of the plug. Inside the plug, the centre electrode is encased in porcelain, which helps transfer heat from the engine to the cooling system. Premium spark plugs make use of precious metals, like platinum or iridium, in place of the nickel alloy. These metals have higher melting points and will be more expensive! Here at AE Services in Sutton our service and MOT deal is very competitive and the spark plugs will be changed as part of this package. For more information go to:

Car Battery

All vehicles need a car battery to start its engine. It is also used in giving the power for the ignition, electrical lighting, and other car accessories. The car battery is an important part of the car that is why, during the winter months a battery check-up is necessary. You may encounter car problems and engine stoppage when the battery is in bad shape. Well-maintained batteries can last for years. There are a few options when it comes to car batteries and there is no difference in what they do but the cost will vary depending on the make you buy. The three main brands used are Exide which come with a 3 yr guarantee, Lion again with a 3 yr guarantee and then the Bosch model which comes with a 4 yr guarantee and as it is a make more commonly heard of today it will be slightly higher in price compared to the other makes on the market. Prices will vary depending on the make and model of the vehicle ranging from around £40+vat up to £80+vat. Here at AE Services in Sutton we can supply and fit a new battery if needed, while you wait. A battery test is carried out before and after a new battery is fitted and a printout given to the customer for their records. If you find yourself unable to start your car due to a flat battery you can usually jump start it with the help of a friend, their car and some jump leads! So if you have concerns about any mechanical problems with your vehicle call us here at AE Services in Sutton and we will help get things sorted.


MOT Failures

Time for your MOT? Here are a few things you can check before you take your car to the garage for a MOT. All external vehicle road lights must be in working order, even the number plate bulbs will fail if not working! If your tyres are below 1.6 mm on the tread this is a MOT fail, the spare tyre is not checked. Check your screen wash level & your wiper blades, they must clean your windows properly, if you’ve got the bonnet open, then it closes & locks that’s another check done as these are MOT failures too! There are certain dash lights that will fail the MOT, these are Airbag Light, Amber Brake Light, ABS & ESP Light. Are all of the seat belts working? Pull them out & plug them in, if they do not click in & stay then this will fail the MOT. Check all doors open and close as this is an important safety issue & will fail the MOT! Honk your horn, if it’s working great, if not that’s a failure! The emission test is to check the gasses coming out of the exhaust these can be affected by poor vehicle maintenance, sensor malfunction or a hole in the exhaust, all of which can be repaired at our garage AE Services in Sutton. A few things you can’t check on your vehicle that can fail during a MOT: Steering arm, track rod ends, wishbones, tie rods, CV gaiters, CV joints, shocks, road springs, drop links, D rubbers, ball joints fueling system, brakes, chassis corrosion, head light aim, severe dangerous oil leak. If you MOT fails we can carry out the repairs need to pass your MOT and this can be done on the same day. Don’t worry, If you feel you are not confident in checking these yourself you can get them checked with our garage if requested before your MOT is due. At our garage in Sutton we offer a FREE text or email MOT reminder service.

Why is Brake Fluid Important?


Brake fluid is what’s known in the auto industry as hydraulic fluid. You may have heard the term ‘hydraulic’ but not know exactly what it means. Hydraulic is simply moved or powered by fluids. That’s exactly what brake fluid does; it moves components in your vehicle’s braking system. Brake fluid has to work under high pressures and temperatures. That’s why it’s so important to maintain your brake fluid, because as it ages it doesn’t work as effectively resulting in inefficient braking. It’s necessary to flush and replace your brake fluid according to manufactures guidelines, when your vehicle is serviced here at AE Services in Sutton the brake fluid will be checked and if needed changed. Brake fluid readily absorbs moisture and over time becomes too saturated with excess moisture, which causes it to degrade. Once moisture content reaches a certain level the brake fluid is no longer able to function properly in the brake hydraulic systems. For reliable, consistent brake system operation, brake fluid must maintain a constant viscosity under a wide range of temperatures, including extreme cold. This is especially important in systems with an anti locking braking system (ABS), traction control, and stability control (ESP), as these systems may use a valve with a time-based approach, rather than measuring pressure or volume to control the amount of fluid transferred. Brake fluid is subjected to very high temperatures, especially in the wheel cylinder of drum brakes and disk brake callipers. It must have a high boiling point to avoid vaporizing in the lines.  A small drop in brake fluid level in the master cylinder reservoir can be ‘topped up’ but if the level is dropping too often, the cause should be investigated and repaired. Brake fluid level in the master cylinder will drop as the brake pads or shoes wear and the callipers or wheel cylinders extend further to compensate. If you are in any doubt as to the effectiveness of the brakes on your vehicle then call us now to book an appointment. For further information, go to

Help, I’ve Put Petrol in My Diesel Car! Fuel Contamination

It’s everyone’s worst nightmare putting the wrong fuel into their vehicle and its only diesel fuelled cars that this can be done to (putting petrol into a diesel vehicle) as the diesel fuel nozzle is bigger than the petrol fuel nozzle which means it will not fit into a petrol tank filling hole. Don’t panic if you find yourself in this situation as it is something that can be sorted out here at AE Services in Sutton. Do not drive your vehicle!! The process for correcting Fuel Contamination is not as straight forward as you might think. It can take around three to four hours and unfortunately can be quite costly. The fuel needs to be drained from the tank first, then providing the vehicle has not been driven the fuelling system is then cleaned out with various additives to ensure that no other fuelling components are contaminated. The engineer will then put fuel into the vehicle and turn the car on to make sure it is running correctly. If you have started your vehicle and driven it (the car will not run smoothly with the incorrect fuel) then it could mean that other fuelling components might be contaminated. If this is the case then the fuel filter will need to be replaced. Other contaminated components which will need cleaning or replacing are the fuel injectors, fuel pump, fuel lines and the fuel tank. Here at AE Services in Sutton we strive on keeping costs as low as possible and our engineers will try where possible to clean and save parts rather than replace them.

Why Is It Important To Service My Vehicle Regularly?

All vehicles come with a recommended service and maintenance schedule which will be carried out yearly or every 6 months depending on vehicle usage. We know that it is easily overlooked but it is vital that you keep this service record up to date to maintain the continued running of your vehicle and to prevent damage being  caused by lack of maintenance. During a service the following items will be replaced: engine oil, oil filter, fuel filter, air filter, pollen filter, if your vehicle runs on petrol then spark plugs will also be replaced. The vehicle will get a full body and engine inspection this includes a brake inspection which is a very important safety issue. Top ups on the screen wash, anti-freeze, gearbox oil and greasing of door hinges, locks and bonnet catches are also done during the service. Another important inspection carried out during the service is on the tyres to make sure the condition, tread and tyre pressure is correct. Here at AE Services we strive to offer the very best service not only on your vehicle but to you as a customer, so call us at AE Services in Sutton to book your vehicle in now.

When should I Change My Timing Belt

The timing belt is a loosely used term and involves more than a belt replacement. It is a complete kit including the timing belt, pulleys and guides which without you cannot start your car. No two vehicles are the same and some vehicles don’t even have a timing belt, they have a timing chain. Timing chains tend to be stronger and more durable than timing belts and will need replacing less often, eventually both will need to be replaced at some point. While there may be some indications that your timing belt or timing chain is in need of replacement, it is not something that you will be warned in advance about. All vehicles will have a manufacturer’s recommended time in years or mileage in which the timing belt should be replaced, you should have your vehicle serviced and the timing belt checked regularly. Unfortunately the damage caused by lack of maintenance on the timing belt can cause serious cylinder head damage which can be costly to repair. Here at AE Services in Sutton all of our customers’ vehicles are regularly maintained and all checks done by a fully qualified engineer to ensure that their vehicle is in perfect working order. If you are unsure as to when your timing belt needs replacing why not book it in now and we can check it for you.


Originally called the ‘Ministry of Transport’ test, it’s now just an MOT. Either way, it’s a safety and legal requirement for cars, motorbikes or any other vehicle.The test information is held on a central database as well as on a paper certificate. It’s the owner’s responsibility to ensure their vehicle’s certificate is valid. You need a test when the car’s three years old (four years in NI), then yearly after that. It is advisable not to wait until the day before the MOT expires to get the vehicle tested, get a test in the month before the current certificate ends and the new one will expire exactly a year from the original’s end date (the earliest date you can do this is printed on your test certificate). But get it tested more than a month before the MOT‘s due and it’ll expire exactly a year later, meaning you lose out. Here at AE Services we will send you an email or text reminder for free. If your car’s out of certification, you can drive it to the test centre provided the test’s been booked. If it’s failed the test, then to get the problems fixed you’re allowed to go from the test station to a repair centre. Here at AE Services in Sutton we can carry out all repair work on site so you don’t have the added hassle of trying to find another garage to carry out any work if needed. MOT stations can only charge up to the official maximum for an MOT. The maximum test costs are £54.85 for class 4 vehicles up to 3000 kg and £58.60 for class 7 vehicles from 3000 kg to 3500 kg, AE Services charge £40.00 for class 4 MOT’s and £45.00 for class 7 MOT’s.
