Most Scions have a black plastic shield over the top of the engine you remove, then disconnect the electrical connection at each of the ignition coils that sit above the spark plugs,the coils are usually secure to the valve cover with a 10mm head bolt, you need a 3/8 drive long extension and ratchet and a 5/8 spark plug socket to remove the plugs.
