Remove the spark plug from the spark plug well.

Install the new spark plug in the reverse order.

When screwing in a spark plug, it is necessary to rotate the spark plug wrench or extension with the head by hand, and not with a wrench or ratchet, to avoid damaging the threads of the spark plug hole in the cylinder head.

If the spark plug does not follow the thread, strong resistance to rotation will be felt. In this case, it is necessary to unscrew the spark plug and, after cleaning the thread, screw it back in again. Finally tighten the spark plug to a torque of 25 Nm.

Attention! Over-tightening the spark plugs can damage the threads in the spark plug holes in the cylinder head.

What candles should I put?

The spark plugs should be those recommended by the car manufacturer. On Volkswagen Polo Sedan cars, SZ VAG10190560F is installed.

They must have the following parameters:

• spark gap from 1.0 to 1.1 mm;
• thread size M 14×1.25;
• heat number 6-7;
• thread length 19 mm;
• tightening torque 25 Nm.

You can supply analogues from other manufacturers:

• NGK - 5960;
• Bosch - 0 242 236 565, 0 242 236 566;
• Denso - KJ20DR-M11;
• VAG - 101 905 617 C;
• NKG - BKUR6ET-10.

You should buy originals, this will reduce the likelihood of acquiring a defect. For example, on products from NGK the original VW part number is engraved.

Before installing the ignition coil, the manufacturer recommends applying a thin bead of lubricating paste (silicone grease can be used) to the inside of the ignition coil plug tip.

We install the ignition coil on the spark plug and press it until it locks onto the spark plug; a click should be heard.

We replace the remaining spark plugs in the same way.

DIY replacement instructions

Any car enthusiast can replace the SZ on a car, since this procedure does not require special knowledge or extensive experience in repair work.

Tools and materials

To carry out the work, you need to prepare a set of spark plugs, a 16" spark plug wrench and a flat-head screwdriver.

Before replacing, all parts should be thoroughly cleaned of dirt to prevent debris from entering the combustion chambers.

An old rag will do for this. After the preparatory work has been completed, you can begin replacement.

The process of dismantling and replacing SZ

To change the SZ to a Volkswagen Polo, you need to follow these steps:

1. First, remove the protective plastic cover with the VW marking. To do this, you need to unfasten the fasteners from the sides by pressing on them.
2. Under the cover there are 4 ignition coils with low voltage wires. They need to be removed to gain access to the NW. You can remove the coils using a flathead screwdriver. The tool is pushed under the spool and the part is gently released by moving upwards.
3. When the coils are reset, the wires must be disconnected from them. To do this, you need to press the latch and pull out the plug with the wires.
4. When removing the coils, you should clean the places where they are installed from dirt and oxidation, which may cause the coils to fail.
5. Next, the old spark plugs are unscrewed. In this case, you should pay attention to their condition. If there are traces of oil, fuel, or black carbon deposits on them, you should find out the cause and eliminate it.
6. We screw in a new set in place of the old products. It is better to screw in the spark plugs by hand until you hear a characteristic click in order to feel if the part is not threaded. The tightening torque should be 25 Nm.
7. After installing the spark plug kit, all wires are connected and reassembly is performed.

After replacing the SZ, you need to start the car and check the operation of the engine.

Replacing the SZ yourself makes it possible to save on car service costs and maintain the technical condition of the car at the proper level.

Timely replacement of spark plugs will extend the life of the engine.

Price issue

There are a large number of companies and types of candles. The most popular are the classic ones, as they are affordable. Platinum and iridium have a longer service life, but their price is higher. Below are classic candles from three companies.

The stability of the Volkswagen Polo power plant depends on the condition of the spark plugs. The presence of misfires in the fuel-air mixture leads to an increase in fuel consumption and worsens the dynamics of the car.

Therefore, the car owner should pay due attention to the condition of the spark plugs. It is required to fully comply with maintenance intervals and purchase only recommended consumables.

Based on the condition of the spark plugs, it is possible to diagnose the power plant and its associated systems. This allows you to identify problems at an early stage and prevent excessive wear of the main components and, as a result, expensive repairs. Therefore, during each replacement of spark plugs, it is necessary to carefully inspect the electrodes and, if they are in an abnormal condition, identify the cause of this and eliminate it.

Replacing Spark Plugs Polo Sedan 1.6

Unique spark plugs for the Polo Car have the factory part number 101905617C . The average cost is 400 rubles. These spark plugs are supplied to the VAG assembly line by NGK (Japan). A direct analogue from the manufacturer is the spark plug under the number ZFR6T-11G (aka NGK 5960 ), the cost is 220 rubles.

Spark plugs Polo Car 1.6

Our client is left with modifications of the Volkswagen Polo Car 1.6; regardless of the engine installed in it (CFNA, CFNB, CWVA, CWVB), similar spark plugs are installed.

Also, not counting the unique spark plugs 101905617C on the Polo Car there are VAG 101905601F , which are themselves unique, alas, less common. The difference between the two models of spare parts is in the manufacturer. 101905601F is produced by Bosch (Germany), the cost is 370 rubles.

The recommended, closer analogue of the unique candle 101905601F from the manufacturer is 0242236565 (aka FR7HC ), cost - 180 rubles.

Both models of unique spark plugs have a nickel electrode, also marked “Long Life”. This development makes it possible to slightly extend the service life of nickel spark plugs.

Dimensions of the unique Polo Car spark plug

In order to increase their service life, you can install spark plugs with an iridium or platinum electrode.

More popular among Polo Car drivers are iridium spark plugs IK20TT , from DENSO (Japan). Cost - 540 rubles.

Also, during the installation of this spare part, drivers notice a slight improvement in the dynamic characteristics of the engine. A spark plug with an iridium electrode can be used for up to 90 thousand kilometers.

Spark plugs with a platinum electrode are also used. In terms of their performance characteristics, they are virtually the same as iridium ones. When, drivers noted no fundamental differences. A very popular model of platinum spark plugs for Polo Car - 0242236566 from Bosch. The average cost is 380 rubles.

Practice shows that spark plugs in unique VAG packaging are overpriced, as they are approximately twice as expensive as their own direct analogues. Therefore, use proven substitutes.

Spark plugs for Polo Car - which ones are better?

Speaking of choosing a higher quality option (not taking into account the price category), the best option is iridium DENSO IK20TT .

Moreover, they are no more expensive than the unique VAG 101905617C in branded packaging.

If you need something from the cost/quality sector, then NGK 5960 (which are a direct analogue of a unique spare part) will be an excellent option for the Polo Sedan.

When to change spark plugs

According to the Polo Car maintenance regulations, spark plugs must be changed every 60 thousand km. mileage Spark plugs with platinum or iridium electrodes can be maintained for up to 80 - 90 thousand km. When installing similar spark plugs, it is recommended to check them after a mileage of 60 thousand km at each subsequent maintenance.

In what cases is it necessary to replace spark plugs?

A high voltage is applied to the SZ, due to which a spark appears between the electrodes, igniting the combustible mixture. The quality of spark plugs affects the efficiency of the internal combustion engine and fuel economy.

Therefore, it is necessary to monitor their condition.

Replacing the SZ on any car is done for two reasons:

• according to the technical maintenance regulations;
• in case of wear or malfunction of the SZ, which causes incorrect operation of the engine.

According to the regulations on Volkswagen Polo cars, replacement of the SZ must be carried out after 30 thousand kilometers.

But you need to change the spark plugs when the following signs appear:

• the car jerks while driving;
• the starter does not fire immediately; several idle revolutions are required to start the engine;
• increased fuel consumption;
• Motor power drops.

In addition, it is recommended to perform a technical inspection of the car after 15 thousand kilometers. During inspection, the condition of the SZ should be checked. Spark plugs require replacement if a visual inspection reveals cracks in the body or peeling of the insulator. It is better to change the entire set of SZ (the author of the video is Avtolikbez).

How to choose and replace spark plugs in a Polo sedan?

How to choose and replace spark plugs in a Polo sedan?

A few years ago, troubleshooting a car usually began with inspecting the spark plugs. Currently, their quality has become much higher, but replacing spark plugs in the Polo sedan should not be neglected.

In most cases, spark plugs are a universal element, but they must be selected strictly according to the catalog.

According to Bosch, 55 main types of spark plugs (out of more than 1000 options) cover 97% of market needs.

In addition to the most obvious parameters, such as the thread diameter (10, 12, 14 or 18 mm) and its length (mostly 19 mm), it is necessary to take into account, for example, the temperature of the spark plug.

Cold ones dissipate heat well and are suitable for heavy-duty units, hot ones - the opposite. The temperature must be selected according to the engine, since spark plugs work best in a certain temperature range.

Individual companies use different factors, so you need to buy spark plugs based on the recommendations of the car or spark plug manufacturer.

There are many brands and types of candles. We recommend products from brands such as NGK, VAG, Bosch, Denso for the Polo sedan. Should you invest in expensive solutions such as platinum or iridium spark plugs? The use of precious metals significantly extends the life of candles, but at the same time their price also increases.

The use of a larger number of side electrodes also improves service life and operating conditions. Other interesting solutions are the V-shaped central electrode (NGK) or, for example, TT technology (Denso) with thin classic electrodes.

Replacing spark plugs in a Polo sedan can most often be done independently, but you need to remember several important principles. The main thing is to cool the engine and thoroughly clean the surroundings of the spark plugs - do not allow any contaminants to enter the cylinder through the spark plug hole.

It is best when we have a torque wrench during installation. Spark plugs with a flat gasket are tightened with a torque from 10 Nm (10 mm thread) to 40 Nm (18 mm thread). The thread should not be lubricated.

How to assess the condition of spark plugs in a Polo sedan?

Spark plugs in the Polo Seadan are subject to routine replacement every 30,000 km. Inspecting a spark plug removed from a Polo sedan engine is very important, even when we remove the spark plug not because of a problem with the block, but simply for the purpose of timely replacement.

A large amount of soot on the insulator and body indicates that the mixture is too rich; an oily Polo sedan spark plug indicates worn piston rings or valve seals. A melted electrode indicates an incorrectly installed ignition.

How to assess the condition of the ignition wires in a Polo sedan?

Designers are striving to eliminate ignition wires - the so-called “direct ignition” will increase the reliability of the system. There is always a replacement period for spark plugs, but not for wires. However, it is worth remembering about them and changing them preventively, for example, after 100 thousand kilometers or in case of deterioration in drive performance. It is, of course, worth using only branded cables.

How to Replace Spark Plugs on a Volkswagen Polo Sedan

Spark plugs are an important part of any car. Their quality directly affects engine performance. Service life depends on many parameters, such as high temperatures, fuel quality and various additives.

Often, a malfunction of the Volkswagen Polo sedan is related to the spark plugs. If the engine stalls, there is a loss of power , the engine does not work properly, fuel consumption increases, then, first of all, it is necessary to check their condition.

After all, the negative factor of a defective part is that the spark plug

may cause failure of the exhaust gas converter, as well as increase the emission rate of gasoline and toxic substances into the atmosphere.

It is necessary to constantly monitor the technical condition of the spark plugs.

All automakers recommend changing them after an average of 15 thousand kilometers. mileage. Typically for the Polo sedan. this is 30 thousand km using only gasoline and 10 thousand km. with gas fuel.

For automobile engines, use spark plugs such as VAG10190560F or equivalents offered by other manufacturers.

There are two reasons for replacing spark plugs in a Volkswagen Polo:

1. Mileage from 30 thousand km. and more (these numbers are indicated in the vehicle maintenance rules).
2. Typical engine faults (“floating” idle, cold engines, etc.).

Technical condition inspections must be carried out at a specialized service center. But if the car is purchased without a warranty and all the necessary tools are available, the replacement and inspection can be done independently.

First, you need to prepare all the necessary tools:

1. Spark plug wrench for 16, 220 mm long.
2. The screwdriver is flat.

All work must be carried out on a cold engine. First, the surface of all parts must be cleaned to prevent debris from entering the combustion chamber.

Detailed description of how to replace spark plugs

ignition for
Volkswagen Polo Sedan
. According to the service book they are...

After all the preparatory work, remove the plastic protective cover from the engine. Its latches are located on both sides left and right and are opened with normal pressure. Under the cover you can see four ignition coils

along with low voltage wires. To get to the spark plugs, you need to remove all of these parts.

The coil is usually removed with a special tool, but, as a rule, this device is only found in technical services. Therefore, use a simple flat-blade screwdriver to remove it. The reset starts from the first coil. To do this, use the sharp end of a screwdriver to slide under the piece and carefully lift the entire structure up.

Once all the coils are out of their places, they need to remove the wires from them. There is a clip on the coil pad, when you press it, you can remove the terminal with wires.

After this, all ignition coils can be removed. Check the contact point between the coil and the plug. If the connector is oxidized or dirty, it should be cleaned as this may be the reason for the plug to fail, otherwise it will cause the coil to fail.

Then, using a spark plug wrench, we turn on the spark plugs one by one. Here, too, you should pay attention to their condition.

The workpiece is considered one, on the surface of which there is no black silt and various liquids, traces of fuel, oil. If such signs are detected, then a number of measures should be taken to determine the malfunction.

It could be a burnt valve causing low compression. Problems may also arise in the cooling system or oil pump.

Installing new spark plugs is done in the reverse order. The recommendation is that they should be wrapped by hand and not by a collar or other assistive devices. If the part is not going with the flow.

it can be felt and corrected. For this purpose, it is necessary to return the candle, clean its surface and repeat the procedure. A torque of 25 Nm is required for tightening. Over-tightening may damage the internal threads on the cylinder.

Which will entail serious repairs.

The ignition coil is inserted before the characteristic click, then the rest of the wires are connected to it. All terminals must be placed strictly in the places where they were. If the installation is incorrect, the vehicle may fail to ignite.

If you follow simple recommendations, difficulties with replacing candles should not arise. This repair is simple and can be done in the garage or outside. Self-charging will not only reduce the cost of paying specialists, but will also save you from problems such as difficult engine starting, loss of power

and high fuel consumption.
