We change spark plugs for Hyundai Solaris with our own hands: which ones to choose?

The spark plug is one of the main elements for maintaining the power unit in working order. Its function is to timely ignite a rich fuel mixture in various engines. The basis of the design is a shell, a ceramic insulator and a central conductor.

Replacing spark plugs for Hyundai Solaris

This process is not complicated and is quite accessible to all drivers who know the location of the candles in the engine compartment.

It is necessary to start work with a cold engine and a disconnected negative battery cable. The sequence of actions is as follows:

1. Using a “10” head and a special “ratchet” tool, unscrew 4 bolts on the plastic engine cover (located on top).

   

   Loosen the screws to remove the cover.

2. Remove the Hyundai logo trim.
3. Provides access to the coils, which are secured with a locking bolt. We unscrew the bolts with a “10” head and remove the coils from the candle wells. The wires are removed with a screwdriver, loosening the clamp on the block.

   

   Loosen the bolts to remove the coils.

4. Use compressed air to clean the area around the spark plug. This method contributes to the effective removal of dust and dirty particles from the metal surface.

   

   Remove the ignition coils.

5. Take the “16” spark plug head (with a rubber band or magnet to hold it in place) and use a long handle to unscrew all the spark plugs in sequence.

   

   Using the 16 key, unscrew the spark plugs.

6. Inspect the spark site for soot and gaps. Thanks to these data, some conclusions can be drawn about the quality of the engine.

7. Install new spark plugs. To do this, simply place the top half on the magnetic head (rubber is not recommended as it often stays inside the well and is difficult to remove) and gently screw the bottom half on without too much force. Compliance with this rule will help prevent damage to the threads of the cylinder block. If there is resistance when screwing in, this is a sign of rotation not in the thread. Remove the spark plug and repeat the process. With a successful turn to the end, pull the sail with a force of 25 N∙m.

It is important to remember that overtightening the spark plugs can damage the threads in the cylinder block bores. After installation, the ease of starting and running the engine is checked. Candles with an expired service life are not restored and must be disposed of.

When to change

Candles must be changed every 35 km.

The manufacturer suggests replacing after 55 thousand kilometers.

In adverse operating conditions, it is worth limiting yourself to 35 thousand km. Perhaps such a short period is related to the quality of fuel at Russian gas stations.

Prices and selection by article

As in other car brands, candles in Hyundai Solaris are divided into original and analogues. Next, consider the options for both types and their approximate price category.

Types of spark plugs

There are the following types of candles:

• long,
• plasma,
• semiconductor,
• incandescent,
• spark - spark
• catalytic, etc.

In the automotive industry, the spark type has become widespread.

A mixture of gasoline and air is ignited by an electric arc discharge that jumps between the electrodes of the candle. This process is repeated in a certain time sequence with the engine running.

The first candles appeared in 1902 thanks to the German engineer and inventor Robert Bosch. Today, the same principle of operation is used with slight design improvements.

How to choose the right candles for Hyundai Solaris

Detailed explanation of the marking on the spark plugs.

When choosing candles, you need to pay attention to the technical characteristics.

Parametric dimensions

If the thread diameter does not match, the candle will not rotate, and the length of the electrodes will not be enough for the normal flow of processes in the combustion chamber. Or vice versa, electrodes that are too large can cause engine piston detonation, which can lead to costly repairs.

Heat number

This is a measure of the thermal limit for normal sail operation.

The higher the digital parameter, the higher the temperature at which the candle can be operated. Driving style should also be taken into account here: with aggressive driving, a mismatch in performance can lead to rapid overheating.

Design features

Platinum candles. Single electrode spark plugs. Multi-electrode spark plugs.

According to their distinctive properties, candles are of three types:

• from precious metals such as platinum, iridium, silver (more durable, self-cleaning and help the engine run economically);
• single-electrode (differs in availability and low cost, fragility);
• multi-electrode (good sparking due to minimal soot).

The best option would be to choose candles made of precious metals. They are more expensive but more reliable. It is also worth noting that high-quality products should be purchased only at official service centers and car dealerships. So the quality of the sparks will be on top.

Conclusion

Timely replacement of candles is 20-30 minutes, and further trouble-free operation - years. The main thing is the quality of fuel and smooth charging mode. Good luck on the roads!
