Removal Procedure
- Turn OFF the ignition switch.
- Spark plug wires from the plugs.
- Remove the spark plugs from the engine.
Caution: Wash your hands after handling coated spark plugs and before smoking. The coating is a non-hazardous material and incidental contact will not cause any adverse effects. However, exposure to polymer vapors - the result of contamination of cigarette products and subsequent burning of the polymer - may result in flu-like symptoms and should be avoided.
Note the position of the wires before removing.
Twist the boot 1/2 turn while removing.
Important:
• Do not remove spark plugs when engine is warm. • Clean dirt and debris from spark plug recess area.
Installation Procedure
- Install the spark plugs.
- Install the plug wires to the proper spark plugs. Use the position reference noted during the removal procedure.
Tighten
Tighten the spark plugs to 15 N·m (11 lb ft).
Important: Aluminum heat shields are used over the spark plug boots on the cylinders which are close to the exhaust tubing. Care should be taken in order to ensure these heat shields are fully seated.
