Need to change spark plugs and fuel filter

What motor is in the 04 Cavalier? If it’s the Eco Tech 4, you need to remove the black cover on top of the engine to access the plugs. Once you remove this cover you will see the coils and the wires for the plug are attached to this cover. Gently remove the plug wires and disconnect the electrical connector from the coils. Set this assembly aside. Using an extension and the correct size spark plug socket. Remove the plugs. With the new plugs check and verify the gap is correct prior to installing the new plugs. One the correct cap has been set, install the new plugs. It is recommend to use a piece of vacuum hose to start the threads on the plugs as to not cross thread the new plugs. One the plugs threads are started use your wrench to tighten the plugs. Do not over tighten as you can strip out the threads. Then reinstall the wires and connect up the coils, reinstall the cover and start the engine. Make sure there is no check engine light and the motor is running correctly.

To change the plugs you could youse a long socket and extension bar and to get the boots back on get a little washing up liquid on ur finger and rub just round the inside of them but dont use alot. once there back on leave for a while to let it dry a little.
