Replacing Spark Plugs on Toyota Yaris

Model: Toyota Yaris Xp10 - Years 1999-2005
Part: Spark plugs

Replace the damaged spark plugs on a Toyota Yaris. Pull the lever to open the engine bay and lift the front bonnet, securing it in place. Remove the air filter box covering the engine head. Undo the side bolts of the coils, remove the coils, then use a socket spanner to unscrew the spark plugs and pull them out of the head. Take the new spark plugs and guide them into the engine head using the socket extension, tighten them securely, refit the power coils, and screw the side bolts back in. Refit the air box and close the bonnet.
