First disable ignition power then remove the engine cover before performing Spark Plug wire replacement. Before removing each Spark Plug boot the technician should twist the Spark Plug wire boot 1/2 turn because only the boot or special tool should be used for removal. The same methodology should be used to separate the Spark Plug wire from the coil before moving forward. The Spark Plug wire installation process starts with fitting the wire onto both the coil first then continuing to each Spark Plug. Whenever you inspect wires you should check for proper installation while pushing the boots sideways to ensure full seating because improper seating leads to wire core erosion causing engine misfire or crossfire conditions. Verify boot seating by pushing each wrist connection until everything fits correctly and tighten any loose wires. During all maintenance procedures keep the wires positioned as they were originally installed to stop radio signals from interfering with the electrical system. Every time you place spark plugs in their boots or install new Spark Plug Wires you must add new dielectric grease to the boot interior. Conclusion includes fitting the engine cover onto the engine then tightening engine cover bolts to 3 n.m (31 lb in).

Turn OFF the ignition and remove the engine cover from the engine.

Twist each spark plug boot 1/2 turn before removing, ensuring to pull only on the boot or use a tool designed for this purpose.

New dielectric grease.

Improperly seated boots can create a false impression of being fully seated, leading to wire core erosion and potential engine misfire or crossfire conditions.
