4 main mistakes when replacing spark plugs

In the technical documentation of modern cars, manufacturers always indicate the life of the spark plugs, after which they must be replaced with new ones. Usually it is 60 thousand kilometers. It should be noted that many factors influence this regulation. One of them is fuel quality. If low-quality gasoline is often poured, the replacement period for spark plugs can be halved.

Many drivers do not consider it necessary to go to a service station to complete this procedure. They prefer to do it on their own. At the same time, statistics show that in 80 percent of cases serious errors are made that can affect the condition of the engine and the experience of the car owner in the future.

4 main mistakes when replacing spark plugs

Consider the four most common mistakes.

Error 1

The most common mistake is to install spark plugs in a contaminated area. Dirt and dust accumulate on the engine during the operation of the vehicle. They can get into the spark plug well and cause damage to the power unit. Before removing the spark plugs, it is recommended that you clean the motor near the spark plug holes. Then, before installing a new one, carefully remove dirt around their holes.

Error 2

Experts note that many motorists make a replacement after a recent trip. It is necessary to wait until the motor cools down. Often, drivers received burns while trying to unscrew a candle from a well.

Error 3

Another common mistake is rush. If you try to perform work quickly, you can damage the ceramic part of the part. If the old candle burst, then before you completely unscrew it, you need to remove all small particles from the engine housing. So there will be less chances for them to get into the cylinder.

Error 4

There are motorists who are sure that it is necessary to tighten all nuts and bolts as much as enough forces. Sometimes even additional leverage is used for this. In fact, it often harms than benefits. In the case of some parts, for example, an oil filter, it is extremely difficult to dismantle them after such a tightening.

The spark plug must be tightened with a torque wrench. If the tool does not have this tool for motorists, then you can control the tightening force in the following way. First, screw the candle effortlessly until it completely sits down to the end of the thread. Then it is pulled by a third turn of the key. So the owner of the car will not break the thread in the candle well, which will have to take the car for a serious repair procedure.

You should always remember: repairing a power unit is always an expensive and painstaking procedure. For this reason, even its maintenance must be carried out as accurately as possible.
