How To Change A Spark Plug In Your Car
You will know that you need to change the car spark plugs when you see that your vehicle has a lack of engine power, which disproportionately increases fuel consumption or, also, when the engine spouts more exhaust fumes. When this happens and you know that the plugs are damaged or in need of a replacement, we explain here on OneHowTo.com how to change a spark plug in your car.
If there is no damage, we need to check the car manual to see if it's passed the required kilometers to warrant a spark plug change. Normally, this is between 30,000 and 60,000.
If this is not the case, you can also learn how to clean a spark plug and wait until you reach the mileage you car's manual indicates to change the spark plug.
If you want to change a spark plug because one of the plugs is defective, bear in mind that you have to put in all new plugs in order to prevent imbalances generated during ignition.
Now, let's start changing you car's spark plug. Leave the car off for two hours or more after its last use since the plugs will be very hot. Disconnect the negative battery terminal (it's vitally important to always do the negative terminal first!).
When you go to buy new plugs, it is recommended that you go with the car manual and that you know the year your vehicle was manufactured in order to purchase the right spark plugs.
Once the engine has cooled down, identify the cables and mark each one with a piece of paper with a number on it to avoid confusion when putting them back into place. There are the same number of wires as there are plugs.
With a glove-protected hand, remove the spark plug wires. Pull from the base, as otherwise the repair will be less effective and it could even break the cable.
After removing each wire, clean the hole, for example, with a small brush.
With a wrench the same size as the spark plug, remove the old plug and replace it with a new one. There is no need to turn the key. You will quickly see that it fits in well.
The last step will be to put in the new plugs and put the wires in their proper positions. Remember that the last thing to connect is the negative terminal!).
