Spark plugs are a critically important element of any gasoline engine that needs timely replacement. The procedure is not so complicated and many car owners prefer to do it themselves. However, even in this simple matter, it is easy to make serious mistakes. It is important to understand that doing the wrong thing when replacing spark plugs can lead to significant repair costs.
How do many motorists? First, replacement is often carried out directly on the street, without preliminary cleaning of the candle wells with compressed air. If there is always order and cleanliness under the hood, then there will be no problems. But, as practice shows, this happens extremely rarely.
Any debris that enters the combustion chamber can pose a real threat to the cylinder-piston group. Although the first symptoms are not always immediately apparent, later this can lead to serious damage to the sleeve or piston, which will result in additional costs. It is also important to remember about the regular replacement of candles, which is recommended every 60-80 thousand kilometers of mileage, writes AmperCar.
High-quality candles can last longer, but problems may arise when they are dismantled. You often have to deal with stuck-on parts that are extremely difficult to unscrew without damaging the threads of the seats. This can lead to the replacement of the cylinder head, which will be a real financial blow. In addition, there are difficulties with the correct tightening of the candles: they are either over-tightened, which can damage the thread, or left under-tightened, which can lead to leaks or other malfunctions.
In the first case, if you do not take into account the possible consequences of improper replacement of candles, you may face the need to replace the head of the cylinder block (GBC), which will cost a round sum. In the second case, if the spark plugs are not properly tightened, misfires will begin, which will not only impair the engine's performance, but may also lead to damage to the cylinder head gasket and overheating of the spark plugs.
And, of course, one cannot fail to mention that excessive savings on consumables will also not bring benefits. Iridium candles are not necessary for every car, but you should not consider completely cheap analogues.
Today, the market offers many proven brands of spark plugs that are suitable for any car and provide reliability and durability. It is better to invest in quality components that will last a long time and will not cause problems during installation or removal.
