I will help you here. You will notice there may be a plastic cover over the top of the engine. Remove the cover if equiped. Next you will see there is two coil packs remove them. Each coil pack will have one boot and one plug wire on it. Carefully remove the boots and wires from the spark plugs. You will see the spark plugs down the holes. Remove them as needed it is best to do this with the engine cold. I hope this helps. If you need clarification or another question answered please ask as positive feedback is very important to me.
There is no diagram per say. If there is a cover it is directly over the top of the engine. Some Ecotecs use a noise quieting cover and others have the air cleaner on top. I hope this helps.
