For many drivers, the process of replacing candles is very difficult, since they do not know which candles to choose, how often they need to be replaced. Many novice drivers do not know what they are for at all. In this article we will talk about what candles are for, what types can be found on the market, which ones are better, as well as how to properly replace candles on a Toyota King.
What are they needed for?
Spark plugs are special devices that allow you to ignite the fuel mixture in the combustion chamber for different types of engines. As a rule, proceeding from their classical version, the mixture ignites by means of an electric discharge running between the electrodes located at the end of the candle. We will not talk about the structure itself. You can study it from the inside yourself. To do this, you need to consider the picture below. Its structure is not complicated and therefore does not require explanation.
Types of spark plugs
Today there are several main types of it. They are subdivided into:
- Classic;
- Platinum;
- Iridium;
- Laser.
The first type is most common for domestic cars... Their electrodes are copper plated. They have the shortest service life, since the metal oxidizes very quickly. Of this type enough for only 50 thousand kilometers.
The second and third types are the most common for modern foreign cars, since their coating oxidizes much longer. There are enough of them for 90 - 100 thousand kilometers of the car's run.
And the last type is laser. The most expensive kind. It was developed by Japanese scientists quite recently, so it's too early to talk about the advantages and disadvantages. It is worth noting one thing - there are no electrodes. The combustible mixture is ignited by exposure to laser beams.
Why change them?
The plugs are changed, as a rule, when there are problems with the engine.
There are many signs that alert the driver that it is time to replace the spark plugs. So, when they become unusable, the engine can lose a significant amount of power - this is due to the fact that the mixture in some cylinders may not ignite. In addition, poor engine starting will definitely be observed. The motor can tremble very strongly, give off vibration. An increase in fuel consumption is also one of the manifestations of candle damage. And finally, the dynamics of the car - it changes significantly, the loss of power makes itself felt.
Instructions for replacing spark plugs on Toyota Corolla
In this manual, a phased replacement will be made on a Toyota Corolla E130 with a 1.6 VVT-I engine. For replacement, VK16 candles were purchased. From the tools we need gloves - in order not to get our hands dirty, a key for 10 and a special candle wrench by 16. Having dealt with necessary tool, raise the hood. The photo below shows the view that we should contemplate in reality.
First of all, we need to remove the engine cover. To do this, we need to unscrew 4 bolts. The photo shows their location. This is not difficult to do and should take you a maximum of 5 minutes.
In order to remove them, we need a key for 10. Carefully unscrew each of them. Their number may be different on different models. This usually depends on the number of cylinders.
Having unscrewed the coil, we need to disconnect the connector and remove it from the ignition coil. This is very easy to do. The photos below show this process.
After the connectors have been disconnected, we take out the coil itself.
So, after completing all the above steps, we got access to the spark plug. We unscrew it with a special key at 16. And take out the old candle.
In its place, we install a new one and twist everything into place. Be sure to connect all the wires. Thus, all the candles are replaced - in the end you will get smooth engine operation, pleasant dynamics, but all this if only the problem was in the candles and they have not changed for a long time.
To all good day! We have frosts in Siberia, and this is the time when you can test the "strength" of the spark plug. Indeed, reliable engine start in cold weather depends on high-quality candles. Today I will tell you how Toyota Corolla spark plugs are replaced. For some, this information will seem useless, while others will do it for the first time. And if our manual is at hand, then the replacement will take place without problems. So let's go.
We had a car at our disposal Toyota Corolla in the 120th body with a 1.6 liter engine. On it we will show how everything is done, but first, a little theory.
Spark plug replacement interval for Toyota Corolla
The spark plugs on the Corolla change in two cases. Firstly, this is an unscheduled replacement when the candles are out of order. Secondly, the time has come Maintenance when you need to change them. If you stick to technical regulations, then this is done after 40 thousand kilometers. By the way, after a similar mileage is necessary. And if AMT is installed on the car, then you may need to pay attention.
Stages of work on replacing spark plugs Toyota Corolla
Please note that Toyota Corolla spark plugs are changed only on a cooled engine. The candles do not change on a warm engine, as this is fraught with stalling threaded connections candles or candle wells.
For replacement, select only those spark plugs recommended by the vehicle manufacturer.
Before starting work, you must arm yourself with a small set of tools, which includes items such as:
Spark plug 16 ", extension and wrench.
- 10 "head with extension and wrench.
- A set of new spark plugs.
So let's go.
1. Open the hood and remove the plastic cover of the motor. This is done in an elementary way. We just tighten two nuts, as shown in the photo below. A 10 "head and a knob are used. Remove the plastic cover to the side.
2. Now we see 4 ignition coils, which fit four control wire harnesses. We need to turn them off. This is done by pressing the latch and pulling the chip to the side.
3. After that, take again our 10 "head with ratchet and extension and unscrew the 4 bolts securing the ignition coils.
Try not to drop the coils, as you can damage them and then you will have to buy new ones.
5. Take the spark plug wrench and unscrew the 4 spark plugs. if possible, it is better to blow out the candle wells before this with the help of a compressor.
6. Remove the wrench or ratchet from the extension and leave only the spark plug head. We insert a new spark plug into it and carefully lower it into the candle well. Then we wrap it by hand so as not to damage the thread. When we are convinced that the candle has gone along the thread, then we take the knob and stretch all the candles with an effort of 25 Nm.
We do a similar procedure with the rest of the candles, after which we collect everything in the reverse order.
That's all! It can be considered that the replacement of Toyota Corolla spark plugs is considered complete. And we recommend that you watch the video on the topic, which will be at the very end of the article. And if you change the oil and doubt its authenticity, then our

Automotive spark plugs are one of the most important parts of engine operation, since it is thanks to them that the fuel is set on fire at a certain moment and the car begins to function. Also, it is the spark plugs that determine the power parameters of the engine and environmental friendliness. exhaust gases... Toyota corolla spark plugs in any weather, especially in cold weather, are the reason for easy engine start. The service life of modern candles is quite long, but they, like any parts, tend to fail due to deterioration in performance.
And now, sooner or later, the time comes to change the spark plugs for Toyota Corolla, but this procedure is very simple, the main thing that you need is to purchase new spark plugs. You can buy them at absolutely any auto parts store, the main thing is to correctly determine which candles are suitable for your car model, since not all analogues may suit you. If you have already decided to choose similar spark plugs, it is better to consult with a knowledgeable person before purchasing them, so as not to make the wrong choice.
What happens due to the failure of candles
Since they ignite the operation of the engine, the spark plugs may burn out and not match the number of cylinders. And when problems begin to arise with their performance, even if the problem is literally a couple of candles, in this case the entire motor system may suffer. On Toyota car Corolla, despite the fact that the candles can be best quality, it is recommended to replace them every 15 thousand or 20 thousand km.
Spark plugs are primarily designed to withstand the highest loads. The situation is the same with oil: expensive and high-quality elements last much longer than cheap counterparts, so it is better not to skimp on car repairs so that you do not have to overpay for their replacement later. If a breakdown occurs, it cannot be postponed, the replacement must be made as soon as possible. If you do this, you will significantly save on fuel and cost savings.
In addition to the fact that candles work in the field of high temperatures, their quality can be affected low level gasoline. If at least one spark plug stops working, then gasoline will stop burning in the cylinder. It will fall into exhaust system, leaving behind a lot of gases, and if a neutralizer of such an exhaust gas is provided in the car, then this is even worse, since it will also soon fail.
Replacing candles

- Next, insert the key into the "well". Do the work carefully and carefully, otherwise you may damage the threads and insulator.
- Remove all foreign objects from the engine, then unscrew the spark plug with a wrench.
- Now it's time to get out the candle. In the event that the candle does not have the required rubber seal, it must be removed using a coil or a piece of polymer tube.
- After you have removed the candles, they must be laid out according to their cylinders.
- Before inserting new plugs, lubricate their threads with graphite grease.
- Put everything back in the reverse order and you're done.
