Model: Toyota Yaris Xp90 - Years 2005-2011
Part: Spark plugs

In this tutorial, you will learn how to remove and replace the spark plugs in a Toyota Yaris VVT-i engine. First, open and lift the bonnet. Remove the plastic cover by unscrewing the side screws; then disconnect the electrical connectors from the spark plugs by unscrewing the fastening screws and pressing on the tabs. At this point, use a socket wrench with an extension to unscrew the spark plugs; then replace them with new ones of the correct type, screwing them in by hand first before tightening with a spanner (preferably a torque wrench).
