Follow the below information to ensure a safe replacement for your spark plugs:

Things to have beforehand

Be sure to have the car's owner manual and read about the type of spark plug and its position in the car.

Buy the number of spark plugs required to be replaced from an authorized shop so that it is genuine and fits the model.

Also have the number of a good technician for help, in case you get stuck while doing the replacement.

While going for the replacement

Along with the spark plug socket and a screwdriver, try to proceed in the following manner to replace the spark plugs.

Let the car engine to cool down

Never apply your hands on a hot engine as it is bad for both your hands and the component of the car.

If the engine is hot, then it is hard to unplug the spark plugs from the aluminum cylinder heads without damaging the threads.

Allow the engine to cool down for safe removal of the spark plugs without causing any damage.

Clean the area around the spark plugs

Take the help of a compressed air duster to blow away the dust and dirt particles around the spark plugs.

While opening the plugs and cleaning the areas, take proper precautions to not allow any foreign particles inside the cylinder.

If any dirt particle gets inside, then it directly falls into the engine and may result in premature engine wear.

Screw the spark plugs straight

Avoid screwing the spark plugs in an inclined manner as it will result in a ruined thread.

To avoid inserting a tilted plug, first rotate them a bit by hand in the hole and if you feel it is getting tight too early, then stop and take it out.

This gives you an idea of the process of screwing and you can fit the plug in a straight manner in the second attempt.

Do not hurry

Do not mix the wires and your work by trying to screw more than one spark plug at a time to complete it faster.

Always play safe and give full attention to a single spark plug for getting it screwed straight and correct.

If you hurry, then things will get messed up and you have to start over all again.
