Video tutorial

Here is a video tutorial explaining how to maintain (or replace) the spark plugs in a Toyota Yaris. Here’s what you need: a ratchet with a 10mm socket, a tube of copper grease, and a spark plug socket with a 16mm opening.

First, unclip the clips that secure the air box. Now you have access to the spark plugs. Using the 10mm socket, loosen the bolt that secures the ignition coil and remove the coil; with the 16mm spark plug socket, unscrew and remove the spark plug.

Apply copper grease to its head, then screw it back into its housing and reinsert the ignition coil. Refasten the coil bolt and reclip the air box clips.
