Service Precautions
1. Twist 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 to remove the boot. Pull on the boot or use a tool designed for this purpose.
5. Special care should be used when installing spark plug boots to ensure the metal terminal within the boot is fully seated on the spark plug terminal and the boot has not moved on the wire.
NOTE: If boot to wire movement has occurred, the boot will give a false visual impression of being fully seated. Make sure that boots have been properly assembled by pushing sideways on the in stalled 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.
^ If they 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.
