Spark plugs on the Opel Astra, as on other cars, are a device equipped with electrodes, insulators and conductive elements. Under the influence of high voltage, an electrical discharge occurs that ignites the fuel - the air mixture in internal combustion engines. High-quality and reliable operation of a gasoline engine depends on the serviceability of the spark plug. Quite often, spark plugs fail, which leads to unpleasant consequences, and the engine itself begins to work terribly.
The article talks about spark plugs for Opel Astra, namely their purpose, signs of malfunction, replacement time, gap between electrodes and much more. After studying the article, you can easily replace the spark plugs in your car.
When replacement is required
Following the technical regulations, the replacement procedure should be carried out every ten thousand kilometers. At the same time, components installed directly at the factory can last you up to 75 thousand kilometers.
The service life also directly depends on the spark plugs themselves: for example, iridium ones can last up to 100 thousand kilometers, and regular ones - a maximum of 30.
Signs that it is time to replace the spark plugs on an Opel Astra and that they are failing will be:
The presence of one or more of the above “symptoms” is a sign that it’s time to purchase new consumables.
Choice
The efficiency of ignition of the mixture in the cylinder is affected by:
All existing candles are conventionally divided into unified, medium, “cold” and “hot”. They are also:
The choice of consumables is not as simple as it seems at first glance. Let's take a closer look at the original and analog components.
Original
Most car owners prefer original SZ. Their cost varies from three hundred rubles and more per piece.
Each of the Opel lines is equipped with its own type of components, for example:
For example, for the z16xer engine, original spark plugs from Opel under article number 1214031 are suitable. The Z18xer is usually equipped with products from NGK under the serial number ZFR5F-11.
The components necessary for stable operation depend on the gap; too small or large a value can lead to rapid failure of the SZ.
Analogs
If you don’t want to overpay, then you can take a closer look at analogues that are not inferior to factory SZ in terms of performance characteristics:
| Brand | vendor code | Price, rub.) |
| NGK | BPR6ES | 250-400 |
| Denso | K20PRU | 150-300 |
| Bosch | 242235668 | 150-300 |
| NGK | 7822 | 100-250 |
| Denso | KJ16CRL11 | 175-300 |
Please note that even inexpensive components are often counterfeited. Therefore, before purchasing, carefully check the box and the candle itself for any extraneous markings, check the colors with the photographs from the catalog. This way you will save yourself from buying a low-quality Chinese copy, which will fail after 3-5 thousand kilometers of the vehicle.
Spark plugs opel astra h z18xer
Good day to everyone, dear subscribers, astravods and those simply coming to visit. A lot of things have accumulated lately, but I’ll probably start with the spark plugs. As I already described in my previous Logbook, in the fight to reduce fuel consumption at idle, NGK ZFR5F-11 spark plugs were purchased, and as was actually clear from the same bulletin board, these spark plugs did not bring the expected result. The consumption was still 0.9 l/hour. As a result, after using these spark plugs for a month and a half, I decided to purchase Bosch spark plugs 0 242 229 699
. I ordered these candles from Exist at a price of 200 rubles/piece. I think what the hell is not joking, what if! The candles arrived in 3 days, made in Germany. I changed them there near the store. The factory clearance on them was 0.95 mm. Moreover, it was absolutely the same on everyone; naturally, I didn’t touch it. I turned it on, started it, warmed it up and went to look at the BC, with the feeling that I wouldn’t see anything new there, but imagine my surprise when, instead of the figures I was already familiar with 0.9-1.1 l/hour, I saw 0.7- 0.8 l/h. My surprise knew no bounds. To celebrate, I stopped by the store)))). The engine, just like with the previous spark plugs, runs smoothly, the idle is crisp, and the response to the gas pedal is also excellent. In general, I concluded that it’s all about the filling of the insides of the candle. I wonder what NGK and Denso are made of if they have such fuel consumption? 1. Spark plugs DENSO VK16 vs GM. 2. Spark plugs DENSO K20TT vs DENSO VK16. 3. Spark plugs NGK ZFR5F-11 vs DENSO K20TT. Here's some more information: The source is here!

Both options are suitable in terms of heat, but the first, cooler one, comes original from the factory, while the second, “hotter” one, has been in use for a good dozen years for hundreds of thousands of asters and other Corsos with insignia and zafirs, with XER series engines. Theoretically, “hotter” candles should last slightly less. Also, theoretically, fans of high speeds and highway runs will be more suitable for “cooler” versions of spark plugs, and for people who drive their cars mainly in city traffic jams, “hotter” ones that clean better at lower temperatures and loads. In practice, both options have positive experience and car enthusiasts should not think too much about this.
Astra H 2007 Z18XER engine. NGK spark plugs. Which?
We have an Astra H Caravan Z18XER 2007. Mileage 40 thousand km.
The spark plugs were changed at an unofficial service center. Installed NGK ZFR5F
.
The car seems to be driving fine. But I just came across information on the Internet that the Z18XER requires slightly different spark plugs - NGK ZFR5F-11
.
Judging by the NGK website, the difference between the spark plugs they supplied me and the “correct” ones is only in the gap between the electrodes.
In NGK ZFR5F the gap is 0.7 mm
, in NGK ZFR5F-11 the gap is
1.1 mm
.
Question. What to do? Should I still replace the spark plugs with the “correct” ones? Or quit and drive like this? What are the consequences of a reduced gap?
VerSerj
And what?
What conclusion can you draw after reading this thread? I saw this:
If I remember correctly, there should be models of spark plugs for XER. Our gap is formally 0.9-1.1, I think 0.7 will not be enough.
In general, the search rules.

Look, there are a lot of them.
The Opel Astra has been produced since 1991 and is a continuation of the Opel Cadet. The car is available with gasoline and diesel engines. There are currently five generations of Astra. The most common ones in Russia are the first (F), second (G), third (H) and fourth (J), which is why they will be mentioned in this article.
Spark plugs for Astra differ depending on engines and generations. Moreover, in some generations there are complete similarities of candles. The supplier of original spare parts is General Motors (GM). There are quite a few manufacturers of the originals, and they varied slightly depending on the generation. The original Astra F and G almost always had spark plugs from Bosch or Beru, the third one had NGK, Champion, Beru, and the fourth one had Champion, NGK, AC Delco or Beru. All originals are supplied in original packaging from GM or Opel.
DIY replacement instructions
So, when is replacement and what devices are best to use for all this, we figured it out. Now we suggest you take a closer look at the replacement process. This procedure can be performed at home without the help of professionals.
In general, the replacement process looks like this:
- First you need to open the hood and disconnect the battery. Then dismantle the cover that covers the NW ignition coils. To do this, you just need to lift the lid with your hand.
- Then remove the plug with wires, which is connected to the block with coils. Having done this, you can unscrew the two bolts that secure the coils. To unscrew these bolts you will need a special star wrench. When unscrewing, be careful not to lose the bolts so that problems do not appear during installation.
- When the coils are unscrewed, you need to grab them with your hands and pull them upward, while swinging them slightly. Opel engines use individual ignition coils, respectively, each of them is installed on each individual spark plug, thanks to which they are installed quite tightly. But in general, this is not a problem; perhaps it will take a couple of minutes to dismantle the SZ.
- As we said above, we will use GM z16xer spark plugs for replacement. These devices are produced by General Motors, which also produces Opel cars. These devices have proven themselves from a positive point of view and are now used everywhere on many vehicles. So, when the coils are dismantled, you can gain access specifically to the SZ themselves. To remove the devices, you will need to use a 16mm spark plug wrench. To properly remove the device from the mounting location, please note that the key must have a rubberized insert that will secure the device when removed. If there is no rubber band or it has already worn out and cannot hold the part, then try using pliers or tweezers.
- Turn out the old spark plugs, while making sure that during removal, no dirt, dust or other debris accidentally gets into the spark plug well, as this will lead to new dilemmas. When installing new spark plugs, you need to install them carefully so as not to bend the electrode of the device. When installation is complete, subsequent assembly steps are carried out in reverse order.
Have you ever had to change spark plugs yourself?
Spark plugs for Astra F and G
Gasoline Opel Astra F with engines 1.4, 1.6, 1.8, 2.0 and generation G with engines 1.2, 1.4, 1.6, 1.8, 2.0, 2.0 Turbo had a lot in common. In particular, the same spark plugs under article number 1214000 were installed on both cars, in all trim levels and with all engines. By the way, they are also installed on some trim levels of the Opel Corsa C. These are ordinary nickel spark plugs with two side electrodes, with a torque tightening 22 Nm.
The dimensions of the original spark plugs for Astra F and G are shown in the table below.
| Thread / thread length, mm | Key size | Gap, mm | Heat number* | Center electrode material |
| M14×1.25 / 19 | 16 | 0.8 | 6 | Nickel |

| Bosch | 0242229654 | 170 |
| Denso | K20TT | 150 |
| Francecar | FCR211057 | 100 |
In addition to the usual nickel analogues, you can install more advanced iridium spark plugs. They last on average 3 times longer and provide better engine performance. For Opel Astra 1st and 2nd generations, the most popular and frequently used iridium spark plug model is Denso IK20TT, price - 610 rubles / piece.
Spark plugs for Opel Astra H
Opel Astra H (third generation) has a wider range of spark plugs. The car was equipped with gasoline engines with volumes of 1.4, 1.6, 1.8 and 2.0. Spark plugs differ depending on the volume and modification of the power unit.
It is worth mentioning right away that on all Astra gasoline engines of this generation, spark plugs come with a short thread and a tightening torque of 22 Nm. Also, the manufacturer installed ordinary nickel spark plugs with one side electrode on almost all engines; they differ only in some parameters (more details in the table below). The exceptions are the 1.6-liter A16LET and Z16LET, as well as the 2-liter Z20LEH engine, which were equipped with platinum spark plugs from the factory, also with one ground electrode.
The original article numbers and sizes of candles for Astra H are presented in the table.

How to replace spark plugs on an Opel Astra N Z16XER hatchback: a detailed guide
- The volume is 1.6 liters.
- Power capabilities are estimated at 116 hp. and 115 Nm.
- “Head” DOHC – 16 valve.
Replacing spark plugs on your own on an Opel Astra H Z16XER is quite possible. The engine layout is simple. Access to the lighters is limited only by the module on which the coils are located. Tools you will need:
- Spark plug wrench 16.
- Screwdriver with the ability to work with nozzles.
- TORX T40 bit.
Preparing for the process does not require any special actions. It is enough to fix the hood and remove the negative terminal from the battery. After this, you can begin to free access to fuel assembly arsonists:
- Remove the decorative cover. To do this, you should pry it with your hand on the right side.
- Remove the power supply block from the unit with the ignition coils.
- Unscrew the two screws securing the module to the motor. You will need a screwdriver with a TORX T40 bit.
- Remove the ignition block.
Note. The coils are installed on each spark plug and sit on them quite tightly. Therefore, the ignition module should be removed by pulling it up and slightly rocking it to the sides.
Once access to the spark plugs is freed, they can be dismantled. The work is carried out cyclically separately for each cylinder: unscrew the old spark plugs, screw in the new ones. Using a 16 mm socket wrench, unscrew the igniter and remove it. To fix the lighter, a rubber insert is provided in the key head. If it is not there, the candle can be removed with tweezers or other available means.
- Work is performed on a cold engine.
- Before unscrewing the igniter, clean the well from dirt by blowing it with compressed air. Otherwise, all the dust and other particles will end up in the cylinder, which is undesirable.
- It is prohibited to throw the lighter into the spark plug well - the electrode may bend.
The removed parts are worth inspecting. Here, diagnostics of spark plugs by appearance is useful, which contains a list of information on the colors of soot and the corresponding states of the power plant.
Spark plugs for Opel Astra J
Opel Astra J (fourth generation) was equipped with gasoline engines with volumes of 1.4, 1.6, 2.0. Spark plugs are different from engines in many ways. On this car, some trim levels are equipped with the same spark plugs as the previous generation (Astra H), since they used the same engines.
Astra J with engines 1.4 (A14XEL, A14XER), 1.6 (A16XER, 1.6 115 hp) and 1.8 (A18XER) had spark plugs with article number 55565219. This is the same spare part as on the previous generation of cars with A16XER engines, Z16XER – after 2010. Therefore, their sizes and analogues are the same. Therefore, they will not be mentioned further in this section.
Gasoline 1.4 Turbo (A14NEL, A14NET) were equipped with iridium spark plugs from the factory, with one ground electrode, and a tightening torque of 28 Nm. 1.6SIDI engines (A16XHT, A16SHT) were also equipped with single-pin iridium spark plugs, but with a longer thread and a tightening torque of 25 Nm.
On Astra 4 with 1.6 engines (Turbo, A16LET), spark plugs 55564763 were installed. They are the same as on the previous (third) generation of cars, which had the same engines. These candles are not mentioned further in the section.
The Opel Astra J with a two-liter A20NFT engine from the manufacturer was equipped with iridium spark plugs with one side electrode, which had a tightening torque of 25 Nm.
More details about sizes and original articles in the table. Spark plugs similar to those installed in the previous generation are not listed here.
| vendor code | Engine | Thread / thread length, mm | Key size | Gap, mm | Heat number* | Center electrode material |

When to change spark plugs on Astra F, G, H, J?
According to the maintenance regulations for Opel Astras (F, G, H, J), spark plugs with a nickel electrode must be changed every 30 thousand km. In reality, their service life, as many drivers say, does not exceed 20 - 25 thousand km. But iridium and platinum spare parts last 60 thousand km without problems, and in many cases longer (especially iridium ones).

How to change spark plugs on an Opel Astra H
Production of the third generation Opel Astra began in March 2004. Officially, its production ended in September 2009, but in Russia the family was produced until 2014 under the name Astra Family. The base was the Delta platform, also used in the production of the Zafira line of cars.
The engines were four-cylinder with a volume of up to 2.4 liters and a potential of up to 240 hp. But the most popular is the Z16XER with a volume of 1.6 liters. Boxes - depending on the on-board power plant: 5/6-speed manual, 4/6-speed automatic, 5-speed Easytronic robot.
Preparation for replacement and necessary tools
Maintenance of ignition system elements that are in direct contact with the internal combustion engine housing must be carried out only after the vehicle engine has cooled down. The process of replacing spark plugs is not complicated; any car enthusiast can do it. To carry it out, the owner of an Opel Astra H vehicle does not need to have significant knowledge and skills, but is required to prepare a specific list of tools, which will be presented below.
What should a car enthusiast have with him? Let's list:
The process of replacing spark plugs
After the owner of the car presented above prepares the specified tools, he can begin to work.
Step-by-step instructions for replacing spark plugs on an Opel Astra N:
- First you need to open the hood of the vehicle, and then remove the plastic cover that covers the spark plugs and coil. You need to pry it out a little with your hand or a screwdriver, as indicated in the photo below;
- Then you need to remove the plug going to the block with coils;
- The next step requires unscrewing the coils; to do this, the car owner should unscrew the two bolts indicated below in the photo. To perform this procedure, he will need a TORX T40 key;
- After the coils have been unscrewed, the car enthusiast needs to remove them. This can be done with your hands, pulling them up, while shaking them a little;
- In the internal combustion engine under consideration, individual coils are used, which is why each coil is placed on a spark plug. Based on this, they are installed quite tightly to each other. Below, the photo shows the result;
- After all the coils have been removed, the vehicle owner can begin to unscrew the spark plugs. To perform the indicated action, you need to use a special 16 key. To remove these car parts from the wells, the spark plug key has a special rubber insert that helps hold the spark plug. If the rubber band is worn out or lost, you can use pliers or other tools suitable for the specified work;
- Finally, the car enthusiast can install new spark plugs in their places. Just don’t throw them into wells, as this may cause the electrodes to bend. Afterwards everything is installed in the reverse order.
As already mentioned, the presented process is not complicated and takes on average twenty minutes.

Replacing spark plugs
Replacement and cleaning of the candle is carried out by a specialist. Regular inspection of parts in the absence of visible signs and damage contributes to a quick response to a breakdown.
Preparing for work
If you replace the spark plug yourself, you need to prepare a 16 mm spark plug wrench, a Toprx T40 sprocket socket and a flat-head screwdriver. Then open the hood and lift the cover protecting the device.
The instructions for replacing the spark plug contain a list of actions:
- gain access to the coil by disconnecting the wires;
- disconnect the coil mount by unscrewing the bolts using an asterisk wrench;
- swing your arms and pull up the freed elements from the candle;
- Having released the ignition system, remove the device using a 16mm wrench with a special rubber insert;
- make sure there are no foreign objects or dust inside the device seat;
- take a new or cleaned old spark plug and install, being careful not to bend the electrodes;
- Reassemble all the parts in reverse order, placing the coils and wires.
- Check engine operation, start the car.
It takes a little time to complete the work of replacing a spark plug; a car owner with no experience can do it in 30 minutes.
Car maintenance involves a visual inspection of the component parts. Spark plugs must be regularly cleaned and replaced while checking the technical condition of the machine so that the engine does not malfunction.
When to change spark plugs, which ones to install
If the replacement is being made for the first time, then remember that factory SZ can last up to 75 thousand km. In this matter, it is also necessary to take into account that a lot depends on the SZ themselves. For example, today you can find spark plugs on sale with a service life of 100 thousand km. Please also note: regular spark plugs last 20-30 thousand, and iridium spark plugs last up to 100 thousand.
The technology for replacing spark plugs on an Opel Astra H Z16XER is not complicated and can be done at home.
In addition, symptoms that indicate the inoperability of the SZ can be indicated, and when they appear, the car owner needs to think about replacing them:

Original arsonists GM 93176801 or Opel 1214031 are recommended for installation on the Opel Astra H. If you cannot find any, you should look at the substitutes offered by well-known companies.
To prevent the technology of cleaning the engine from carbon deposits inside from becoming relevant in the near future, it is worth dividing the lighters into “warm” and “cold”. The former are recommended for use in conditions of predominantly urban movement. They have a lower heat number, and therefore the self-cleaning temperature is lower.
According to reviews, products from other brands are also actively used. These are Beru Z 203 and Autolite XP5224.
Selection of spark plugs for the Z16XER engine
The ignition system on this engine is very capricious. An unreliable igniter element or a non-original coil unit can damage the ECU. The manufacturer speaks about this unobtrusively and loudly from mechanics who have encountered similar cases more than once.
To follow the recommendations and replace spark plugs on an Opel Astra N with a Z16XER engine, you should look for products under GM codes 93176801 or Opel 1214031. If such parts are not available, do not be upset. They have plenty of analogues from well-known companies.
Thus, some of the spark plugs approved for use on the Opel Astra power plant in question are Denso products:
- VK20 (have an extended service life because they have iridium and platinum electrodes).
- K20TT (equipped with thin electrodes with a gap of 1 mm).
- KJ20CR-L11 (standard).
- IK20L (iridium “tip”, but the service life is normal).
- K16TT (thin).
- VK16 (platinum + iridium: extended life).
- KJ16CR-L11 (standard).
- IK16L (product with iridium electrodes and normal service life).
Products from other companies are also available for use. For use primarily on the highway, regular Bosch parts (colder ones) are suitable:
- FR7LCX+.
- FR7LPX.
Bosch also has “warmer” analogues:
- FQR8LEU2 with 0.9 mm gap.
- FR9LCX (often used by Opel Astra owners).
To replace them, you can use products with a low heat rating from NGK:
- ZFR5FIX-11.
- ZFR5V-G.
- ZFR5FIX-11P.
There are also “cooler” candles in the assortment:
- ZFR6FIX-11.
- ZFR6V-G.
- ZFR6FIX-11P.
According to reviews, products from other brands are also actively used. These are Beru Z 203 and Autolite XP5224.
Problems with the ignition module
The ignition module on the 1.8-liter Opel Astra H engine is a consumable that should be changed every 70,000 km. It simply fails, which is manifested by engine trouble and misfires.
Its service life is shortened by untimely replacement of spark plugs, installation of low-quality spark plugs and spark plugs with a large (more than 1.1 mm) gap. As well as moisture getting into the spark plug channels due to too diligent engine washing or simply due to condensation falling out of the air. Therefore, the season for breakdowns of ignition modules usually occurs in the autumn-winter period.
A breakdown of the ignition module usually manifests itself as a breakdown of its insulation. People have already come up with many ways to repair broken insulation: from patching it with epoxy glue to “putting on” thick heat-shrinkable tubes.
The Opel Astra H engine ignition module is a consumable. Usually it does not travel more than 70,000 km. If the insulation breaks down, it can be restored using heat-shrinkable tubing.
Symptoms of a node malfunction
Characteristic and obvious symptoms that make you think about replacing or repairing the ignition module on an Opel Astra H are:
The reasons for spare part failure may be:
The most common reason why a module fails on an Astra H is a violation of the integrity and tightness of its housing. In other words, a breakdown of the housing occurs and a through gap (hole) is formed in it. In this case, it is necessary to restore the tightness of the module, but you need to understand that this is a temporary measure and in the future the part will still have to be replaced.
Why does it break?
There are several reasons why the MZ fails in Opel Astra H cars or on any A16xer engine.
Usually they are caused by improper operation of the vehicle, but there are others:
To prevent the spread of faults, experts recommend diagnosing the gap between the spark plugs every 15 thousand km. If there is a gap, it is necessary to adjust it between the electrodes.
Restoration work of the ignition module (coil).
Let's deal with one of the most unpleasant and common problems in the Opel Astra H car, a malfunction of the ignition module. The car was produced in 2007, the engine stalled, the Check Engine error popped up on the dashboard, and the revs began to fluctuate. An unpleasant sound is heard when you press the gas pedal.
Diagnostics showed a malfunction of the ignition module (coil). The price of a new ignition coil from Delphi is around 6 thousand rubles. Let's try to do the repairs ourselves, saving money:
How long will this repair last?
It’s different for everyone, in this example the driver has already driven more than 30 thousand km. mileage, 2 years have passed, the coil is still working. Some people, having carried out such a repair of the ignition module with their own hands, buy a new part and carry it with them all the time, just in case.
Why is this happening:
It’s impossible to say 100% for sure, but most likely due to the rubber tips. Their bottom dries out from contact with heated candles, as a result microcracks appear, a spark begins to break through them onto the body, “eating away” at the shells in this place. To prevent the problem, I recommend buying and replacing rubber bands; they cost several hundred rubles.
In what cases such repair will not help:
On this car, the coil did not burn out, but simply began to pierce the body. If the ignition module burns out, nothing will help it; you need to buy a new part.
In what cases is it necessary to replace spark plugs?

Opel Astra H spark plug replacement
In accordance with the technical regulations, replacement of spark plugs in the Opel Astra J must be performed every 10 thousand kilometers. If the replacement is being done for the first time, then remember that factory SZ can last up to 75 thousand km. In this matter, it is also necessary to take into account that a lot depends on the SZ themselves. For example, now you can find spark plugs on sale with a lifespan of 100 thousand kilometers. Please also note: ordinary spark plugs last 20-30 thousand, and iridium spark plugs last up to 100 thousand.
In addition, symptoms can indicate the inoperability of the SZ, and if these occur, the car owner needs to think about replacing them:
- When you try to start the engine, turn the starter device for a very long time, but the unit does not start or starts, but with great difficulty.
- The unit began to make unpleasant sounds when warming up, which appeared especially clearly at idle.
- Fuel consumption has increased.
- The volume of harmful substances that come out with exhaust gases has increased.
- If you unscrew the SZ, you can see that they are wet or filled with fuel.
- The power and thrust of the vehicle’s engine as a whole has decreased, the engine is having difficulty gaining the required speed (the creator of the video is Quadro Maniacs).
The process of replacing spark plugs
After the owner of the car presented above has prepared the indicated tools, he can begin work.
Step-by-step summary of replacing spark plugs on an Opel Astra H:
- First you need to open the hood of the vehicle, then remove the plastic cover that covers the spark plugs and coil. You need to pry it off a little with your hand or a screwdriver, as indicated in the photo below;
Remove the plastic cover
- Then you need to remove the plug going to the block with coils;
- The next step requires unscrewing the coils; to do this, the car owner should unscrew the two bolts indicated in the photo below. To perform this procedure, he will need a TORX T40 key;
Unscrew the marked bolts
- After the coils have been unscrewed, the car owner needs to remove them. This can be done with your hands, stretching them upward, while swaying them slightly;
We take out the coils
- The gasoline engine in question uses personal coils, which is why any coil fits onto a spark plug. Based on this, they are installed quite tightly to each other. Below, the photo shows the result;
The result of the above action
how to change spark plugs in Opel Astra H
- After all the coils have been removed, the vehicle owner can begin to unscrew the spark plugs. To perform the indicated action, you need to use a special key 16. To remove these car parts from the wells, the spark plug key has a special rubber insert that helps to hold the spark plug. If the rubber band is worn out or lost, you can use pliers or other tools suitable for the designated work;
Unscrew the old spark plugs
- At the end, the car owner can install new spark plugs in their places. Just don’t throw them into wells, because this could result in the electrodes being bent. Afterwards everything is installed in reverse order.
As already mentioned, the presented process is not complicated and takes on average 20 minutes.
