In this tutorial, we learn how to replace spark plugs in a 2005 Jeep Grand Cherokee. First, prop your hood up and leave it open. Next, remove the hoses around the spark plugs and use a wrench to remove the casing around the plugs. After this, squeeze the top of the connector and unplug the wires. Next, remove the spark plugs and replace the new ones back inside. When you are finished, you will need to replace all the items that you removed, making sure to replace everything where it was originally placed at. Clean the inside of the engine while you have it open, then you're done.
