How to Change The Spark Plugs?

Here’s how to change the spark plugs of your vehicle in 7 easy steps:

1) Locate Your Spark Plugs

First of all, you must bear in mind that these changes are made with the engine off and you must wait at least 2 hours from the last time you used the vehicle. Spark plugs are normally located at a glance or are under a protective plastic housing that covers the engine.

2) Disconnect The Spark Plug Wires

Remove the wires one by one by pulling the cap and not the cable itself as you can damage them. Remember where each cable came from and what coil they were going to. If you put them wrong then the vehicle will not even start on.

3) Remove the Spark Plug And the Ignition Coil

Grab the hexagonal ratchet and spark plug wrench and unscrew the ignition coils to remove it. To remove the spark plugs, turn them anticlockwise then finish them off with your own hands.

NOTE: In some vehicles it is not necessary to remove the ignition coils.

4) Blow the Orifices of the Spark Plugs

Put the safety glasses on and then with the blower begin to blow each hole of the spark plug to make it free of particles or unwanted elements.

5) Screw the New Spark Plug

Grease the spark plugs and begin to screw it by hand very carefully and with little pressure. When the spark plug is screwed in, use the wrench and turn clockwise to tighten it. Be careful not to apply to much pressure. You should leave them similar as before.

6) Place the Ignition Coil

Put the ignition coil back into place using the hexagonal ratchet to screw them. Remember that you should not exert too much pressure when tightening them as you could damage the thread and break the coil itself.

7) Connect the Wiring and Repeat the Process With Each Spark Plug

Once the ignition coil is fixed, reconnect the wiring each as it was in place.

Congratulations! You have successfully learned how to change the spark plugs on your own
