REMOVAL
3.7L V-6
Each individual spark plug is located under each ignition coil. Each individual ignition coil must be removed to gain access to each spark plug. Refer to Ignition Coil Removal/Installation.
Remove necessary air filter tubing at throttle body.
Prior to removing ignition coil, spray compressed air around coil base at cylinder head.
Prior to removing spark plug, spray compressed air into cylinder head opening. This will help prevent foreign material from entering combustion chamber.
Remove spark plug from cylinder head using a quality socket with a rubber or foam insert. Also check condition of ignition coil o-ring and replace as necessary.
Inspect spark plug condition. Refer to Diagnostics and Testing - Spark Plug Conditions.
4.7L V-8
Each individual spark plug is located under each ignition coil. Each individual ignition coil must be removed to gain access to each spark plug. Refer to Ignition Coil Removal/Installation.
Remove necessary air filter tubing at throttle body.
Prior to removing ignition coil, spray compressed air around coil base at cylinder head.
Prior to removing spark plug, spray compressed air into cylinder head opening. This will help prevent foreign material from entering combustion chamber.
Remove spark plug from cylinder head using a quality socket with a rubber or foam insert. Also check condition of ignition coil o-ring and replace as necessary.
Inspect spark plug condition. Refer to Diagnostics and Testing - Spark Plug Conditions.
5.7L V-8
Eight of the 16 spark plugs are located under an ignition coil; the other 8 are not. If spark plug being removed is under coil, coil must be removed to gain access to spark plug. Refer to Ignition Coil Removal/Installation and observe all CAUTIONS and WARNINGS.
Before removing or disconnecting any spark plug cables, note their original position. Remove cables one-at-a-time. To prevent ignition crossfire, spark plug cables MUST be placed in cable tray (routing loom) into their original position. Refer to Spark Plug Cable Removal for a graphic.
Before installing spark plug cables to either the spark plugs or coils, apply dielectric grease to inside of boots.
Remove necessary air filter tubing at throttle body.
Prior to removing ignition coil (if coil removal is necessary), spray compressed air around coil base at cylinder head cover.
Prior to removing spark plug, spray compressed air into cylinder head opening. This will help prevent foreign material from entering combustion chamber.
