Service Precautions

1. Twist the boots one-half turn before removing.
2. When removing the boot, do not use pliers or other tools that could tear the boot.
3. Do not force anything between the wire and the boot, or through the silicone jacket of the wiring.
4. Do not pull on the wires in order to remove the boot. Pull on the boot or use a tool designed for this purpose.
5. Carefully install spark plug boots in order to ensure that the metal terminal within the boot is fully seated on the spark plug terminal and the boot has not moved on the wire.
6. Any time the spark plug wires or boots are installed on the spark plugs, new dielectric grease needs to be applied inside the boot.

Notice: 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.

7. If the boots have been correctly installed, a stiff boot with only slight looseness will be noted. If the terminal has not been properly seated on the spark plug, only the resistance of the boot will be felt when pushing sideways.

Wire routings 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 properly can lead to radio ignition noise and crossfiring of the plugs, or shorting of the leads to the ground.
