4. Disconnect the spark plug wire from the coil (2).
Installation Procedure
1. Install the spark plug wire on the coil (2).
2. Install the spark plug wire (1) at each spark plug.
Caution:
If the boot to wire movement has occurred, the boot will give a false visual
impression of being fully seated. Ensure that the boots have been properly assembled by
pushing sideways on the installed boots. Failure to properly seat the terminal onto the spark
plug will lead to wire core erosion and result in an engine misfire or crossfire condition, and
possible internal damage to the engine.
3. Inspect the wires for proper installation:
Caution:

from each spark plug.
• Twist each spark plug boot 1/2 turn before removing.
• Pull only on the boot or use a tool designed for this purpose in order to remove the wires
from the coil.
• Push down on each boot in order to inspect the seating.
• Reinstall any loose boot.
• Wire routing must be kept intact during service and followed exactly when wires have
been disconnected or when replacement of the wires is necessary. Failure to route the
wires correctly can lead to radio interference and crossfire of the plugs, or shorting of the
leads to the ground.
• Any time the spark plug wires or boots are installed on the spark plugs, new dielectric
grease needs to be applied inside the boot.
