Ignition Coil: Service and Repair
Ignition Coil
REMOVAL
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.
An individual ignition coil (1) is used at each cylinder. The coil mounts to the top of the valve cover with 2 bolts (2). The bottom of the coil is equipped
with a rubber boot to seal the spark plug to the coil. Inside each rubber boot is a spring. The spring is used for a mechanical contact between the coil and
the top of the spark plug.
1. Depending on which coil is being removed, the throttle body air intake tube or intake box may need to be removed to gain access to coil.
2. Unlock electrical connector by moving slide lock first (1). Press on release lock (3) while pulling electrical connector from coil.
3. Disconnect secondary high-voltage cable (2) from coil with a twisting action.
4. Clean area at base of coil with compressed air before removal.
5. Remove two mounting bolts (6) (note that mounting bolts are retained to coil).
6. Carefully pull up coil from cylinder head opening with a slight twisting action.
