Replacing spark plugs and ignition coils on any vehicle equipped with a gasoline engine is part of the scheduled maintenance. Skoda Octavia A5 and A7 cars are equipped with an MPI injection system engine, which is equipped with multi-point fuel injection into each cylinder. In this article we will talk about the selection and replacement of spark plug coils on Skoda Octavia A5 cars with MPI 1.6 and TSI 1.4, 1.8 engines.
Let's start with diagnostics
The principle of operation of the Skoda Octavia gasoline engine is to burn fuel in the cylinders, in turn, these fuels must be ignited, and this is the task that spark plugs and ignition coils perform.
If the engine on your Skoda Octavia Tour has started to run rough and you feel a loss of power, it is possible that you need to replace the spark plugs or ignition coils. Skoda Octavia TSI engines are very whimsical about the condition of spark plugs, as well as coils, since this unit is equipped with a turbocharger, which leads to accelerated combustion of fuel.
Skoda Octavia 1.4 and 1.8 TSI motors have a similar design and require replacement of candles and high-voltage coils, as well as wires, every 30 thousand kilometers. Of course, these parts can work even 60 thousand kilometers, but the quality of fuel combustion will noticeably deteriorate and the engine will lose some of its power, especially the 1.6 liter Skoda Octavia unit.
Spare parts selection
To know which spark plugs and coils to buy, you need to know the original number of these parts. As a rule, it is located on the side of the part.
There are a large number of manufacturing companies that produce high-voltage parts for any car, including the Skoda Octavia Tour. In order not to buy a fake, you need to make sure of the quality of a particular manufacturer whose parts you are going to purchase.
The selection of these parts on 1.6 engines is identical to other Skoda Octavia Tour power units.
We make a replacement
To change spark plugs on Skoda Octavia 1.4 and 1.8 TSI engines, as well as 1.6, you must have a candle wrench and a set of socket heads, as well as hexagons and screwdrivers, on hand. You can find a lot of video material demonstrating this process.
Attention! Before starting these works, it is necessary to remove the key from the ignition lock and remove the high-voltage wires.
- First, remove the plastic engine cover on the Skoda Octavia Tour using a tool.
- We unscrew several bolts securing the coils on the valve cover of the 1.6 engine.
- We remove the connector on the part and dismantle the entire element, as shown in the video on the Internet.
- Using a 16 mm candle wrench and a long extension cord, we unscrew each candle individually.
Before dismantling, it is necessary to clean the grooves from dust and excess objects using compressed air.
- Install new parts and carefully tighten the spark plugs. You can’t pull hard, otherwise you can ruin the thread in the head housing of the 1.6 liter unit.
- We install new coils and wires, after which we connect the electrical connector and tighten the bolts.
- Put the plastic cover back in place. The video on the Internet clearly shows this moment.
The replacement and maintenance of the high-voltage part can be considered complete.
Conclusion
Summing up, there are several things to note:
- Purchase high-quality components for your Skoda from trusted sellers.
- You can replace high-voltage elements with your own hands, without contacting a car service.
- Use video instructions from the Internet for a visual perception of the replacement work scheme.
- Check the high voltage part every 30 thousand kilometers and your car will last for many years.
The choice is yours alone.
According to the list of routine maintenance for the Skoda Octavia A5, spark plugs should be replaced every 60,000 km, condition control - every 15,000 km. Depending on the type of engine, the procedure will differ significantly. In this article, we will consider the sequence of actions when replacing candles "aspirated" 1.6 MPI BSE.
Original spark plugs for 1.6 liter engine - BKUR6ET-10NGK. Catalog number - 101 000 033 AA. We pay attention to the designation "-10" in the marking - it indicates that the gap between the electrodes of the candle is 1.0 mm. If there is no such figure in the marking, then the gap is 0.8 mm. The 1.6 MPI engine uses spark plugs with a millimeter gap, so be careful when ordering.
The price of one candle is 300-400 rubles. This means that a set of four pieces will cost approximately 1200-1600 rubles. Iridium spark plugs with improved performance cost 2 times more than regular ones, but they last about twice as long. If you want to increase the interval between replacements, choose them.
Get to the spark plugs of the 1.6 MPI 102 hp engine. not so easy. To facilitate access, it is recommended to remove the intake manifold, but you can do without it. We will consider both options.
Replacing spark plugs with intake manifold removal
If you dismantle the collector, then there is free access to all four candles, and it will not be difficult to replace them. However, this method has its drawbacks. The first - in addition to the collector, you will also have to remove the additional air supply pump located nearby. The second is that the operation of dismantling the collector is not the easiest, and besides, it is recommended to change the gaskets every time it is performed, and these are additional financial and time costs. However, it is the method with the removal of the intake tract that is preferable when replacing Skoda Octavia A5 1.6 MPI spark plugs.
So, first remove the pump of the air supply system. To do this, disconnect the two inlet sleeves by squeezing the latches and pulling the hoses up. Next, we unscrew the four screws of the pump mounting bracket and disconnect the connector. We take out the bracket assembly with the pump.
Now you can do the intake manifold itself. To remove it, you must first unscrew the two screws from the top (attachment to the receiver), and then 6 bolts and 2 nuts from the bottom (attachment to the cylinder head). Just below the collector is a metal bracket, it is also desirable to remove it.
To unscrew the candles, you will need a special “16” candle key. Before replacing, it does not interfere with cleaning the candle wells from dirt so that it does not get into the cylinders. If the wells are clean, you can proceed directly to the replacement. We start with the first cylinder. First, remove the tip of the high-voltage wire, then turn it out and take out the candle. We screw in a new one in its place, and first we twist it by hand, and then we tighten it with a key. In the same way, we change the remaining three pieces.
The main thing when twisting a new candle is not to overtighten it. It is guaranteed to get the right force using a torque wrench. According to the documentation, the tightening torque of the spark plugs is 25 Nm.
Assembly is carried out in the reverse order. After completing the procedure, we start the engine and listen to how it works. The motor should run about the same as before the replacement. The condition and color of the electrodes of old spark plugs can tell a lot about the condition of the engine itself, possible problems, the quality and composition of the fuel-air mixture.
Replacing spark plugs without removing the intake manifold
You can change spark plugs on a Skoda Octavia A5 with a 1.6-liter engine without removing the manifold, but in this case access to the spark plugs will be difficult. The most difficult thing will be to get to the candles of the 2nd and 3rd cylinders located under the collector sleeves. To unscrew it, you need to remove the connectors from the injectors and use a key with a cardan drive that allows you to transmit torque at an angle. We will not describe the procedure itself in detail, we will simply give a video instruction.
Spark plugs in a Skoda Octavia A7 car play a primary role in igniting the air-fuel mixture, due to which the pistons move in the cylinders and rotational motion is transmitted to the crankshaft. Their work is directly related to the ability to move any car. Even a slight instability in operation can lead to a significant reduction in engine performance on the SKODA OCTAVIA Octavia III (A7) hatchback. Therefore, candles must be monitored with special care, and replaced with new ones in time. And the easiest way to do this is with the help of our store, which offers a wide selection of original spark plugs for Skoda Octavia A7, as well as their analogues at better prices.
When to change spark plugs for Skoda Octavia A7
If the spark plugs are malfunctioning, the following symptoms may occur:- difficulty starting a cold engine;
- the presence of "triple", that is, during engine operation, twitching is noted;
- increased fuel consumption;
- inadequacy of the engine response to pressing the accelerator pedal;
- "floating" turns and a number of others.
