Original Ford Focus Candles 3. Ignition Candles, Replacement, Status Assessment, Analog Selection

On average, the candle should leave 30,000 km, but the experience shows that this resource in practice is almost twice as much and reaches 50,000 km. Ford recommends on changing the candles, regardless of their condition, that is, 45,000 km.

Ford 1493001 - Original Ignition Candle for 1.6 (85PS, 1005PS)

Candles are better changed on time, especially if there are suspicion of them.

On Ford Focus 3, different candles are put depending on the volume and power of the motor:

• 1.6L Duratec Ti-VCT (105PS) - 1493001 , cost 150 rubles;
• 1.6L DURATEC TI-VCT (85PS) - 1493001 ;
• 1.6L Duratec Ti-VCT (85PS, 105PS) - 1787829 ;
• 1.6L DURATEC TI-VCT (125PS) FFV-SIGMA - 1680032 or 1698597 , Cost 250 rubles.
• 2.0l Duratec Tivct (154ps) - 5115895 (Date of production: on 2011/07/07) or 5211024 (Date of production: from 2011/07/07). Price 370 rub.

Candles are sold individually. For replacement of candles in Ford Focus 3 requires 4 candles. The best to use original candles with the corresponding power units. Externally, the candles can be similar, but their characteristics are different and have a fine tuning under a certain power.

Due to the small cost of original candles and good quality, as a rule, everyone uses the original. Also possible replacement options, they go universal to all types of engines for example NGK T5B13 or NGK 96463.. Price 120 rub.

Candles NGK have good quality, no wonder they produce official candles for Ford. These candles have similar characteristics with the original and similar price. It is worth choosing solely from their preferences.

Each company, the manufacturer of candles, uses its technologies and materials, but the general characteristics and their service life is about the same. You can select original candles, they are chosen under a certain car, thanks to which the greatest positive effect is achieved. While the analogues are universal, under different models and stamps with similar characteristics, so their properties are averaged under the selected model range, which reduces their effectiveness.

The spark plugs on average are about 20,000 - 30000 km of mileage, after which they must be changed. If the Ford Focus 3 refuel the high-quality fuel and not give it excessive loads, they will work out all the time without problems. However, in the case when the motor began to function incorrectly, it is not necessary to wait - their replacement is mandatory. In our article we will talk about how to correctly change the candles when you need to do and what features should pay attention to.

In many ways, the lifespan depends on how the Ford Focus is operated 3. For example, if you constantly drive at low gear and low revolutions when the motor gets an increased load, then the nagar will be much larger than under normal conditions. Also affects the quality of fuel, as mentioned above. If we take the Ford Focus and maintain it to maintain it, then the candles can serve to 40000 km, after which they will follow their replacement. The fault of the candles can be detected independently if Ford Focus began to behave not as usual. The main features, after the appearance of which it is worth changing the candles, are:

1. Increase the fuel consumption in all ride modes.
2. The engine stalls at idle.
3. Motor is bad (the starter works, but the start of the engine does not occur).
4. Motor Troit and works unstable.
5. The dynamics of the car worsens, he slightly accelerates and slowly gains momentum.

Preparatory work

If the symptoms described above appeared on your Ford Focus 3, this means that the candles must be changed. When carbon or cracks are detected on parts from ceramics, it will also be replaced. Periodically, you need to check this part on the breakdown using a special device. I ignoring it, a more serious problem may be formed - the ignition coil fails, and its replacement will cost much more than 5 times).

On Ford Focus 3 Replacing the spark plugs should be made either on a cold motor or a little heated. The fact is that on the hot engine they should not get out. If this happens, then most likely there is some kind of problem with a thread of cylinder heads, which is made of light and not very durable metal and will need to be changed.

Before you start changing the candles on Ford Focus, prepare all the tools that you may need to work. It is also recommended to have special devices to determine the gap of the candles. So, you will need the following tools:

• Candle wrench to 16 (you can choose any, but high-quality options are keys 3122B or HAZET-900 / AKF);
• Ticks for unscrewing;
• Device for measuring the gap.

In addition, you, of course, need a set of spark plugs from 4 pieces. As for a particular choice, it is necessary to be guided by the manufacturer's recommendations and buy products of authoritative firms.

So, the most correct option for Ford Focus is the purchase of a set of candles, checking their gap and adjustment alternately for further replacement. As soon as you get everything you need, you need to wait for the complete cooling of the motor and only then proceed to work. This time is enough to check out new spark plugs and determine the gap. To measure the gap, you need to use a special device.

Features of replacement of candles

Getting to work on replacing ignition candles. To do this, turn off the ignition and perform the following actions:

1. Remove the Ford focus engine cover by unscrewing the fastening bolts.
2. Remove the plug connections of the ignition coil. This can be done by pulling up special strap up.
3. We unscrew the coil fixing bolts to the cylinder head and raise them up. It is also necessary to inspect the place of attachment of the cylinder head and the coil on the subject of damage to the seal. If necessary - change.
4. Unscrew the candles with the key. It is necessary to do so carefully, so as not to damage the ceramic case, using special keys mentioned above.
5. Check the new candle on the interelectrode distance. As a rule, manufacturers exhibit everything correctly, but if there is some inconsistency, it must be eliminated. To do this, you need to adjust the mass electrode by tapping on the side. I repeat, it is strictly forbidden to rely on the central electrode. The edge can be the edge of the thread.
6. We smear a special composition with a high content of copper on the thread.
7. Install the candle in the Ford Focus cylinder head and screw it with your fingers, then fix the candle wrench. (To avoid incorrect twisting, put on the shank plastic tube or rubber hose, which will work as a hinge and align the candle with respect to the nest, without allowing the thread breaking).

As you could already understand, changing the spark plugs - it is a pretty simple thing to Ford Focus. It remains to connect high-voltage wires. Before doing this, they must be carefully examined. If everything is in order, then by rotational movement put the wire of the wires in place. Perform the same actions for each candle. When you learn how to do this, there will be no problems and the process will not take a lot of time. Last - Stage - Install the Ford Focus engine cover and everything, the replacement is completed.

Dear teammates!
In this post, I collected briefly basic information on candles accumulated over the years. There will be no huge list of candles of other manufacturers. But you will find information that will help independently choose the manufacturer you like and choose suitable spark plugs.
For the selection of the candle, you need to know:
- Geometric parameters: diameter and thread length, key size, landing type that can be obtained from marking. Two marks are applied on the original candlelight: MotorCraft and conveyor manufacturer, which allow you to compare the original candles with different FINIS codes, analogues from the conveyor manufacturer, choose the candles of another manufacturer.
- Gallery: Selected relative to the original in accordance with the matching table. It is not necessary to observe. You can choose how little colder if riding mainly on the highway or aggressive and warmer - if riding short runs, especially in winter.
- The gap between the electrodes: it is pre-installed by the manufacturer and is indicated in the marking, it is desirable to choose a candle with a nominal gap +/- 0.1 mm. If the manufacturer has liked, the manufacturer does not have with the desired gap, it can be adjusted by sublexing the side electrode within up to +/- 0.3 mm.
- Type of electrodes: copper, platinum, iridium, thin, ultra-thin, with refractory attacks and without - what manufacturer lures us, promising improvement of the characteristics.
