NOTE:
Observe the following service precautions:
- Allow the engine to cool before removing the spark plugs. Attempting to remove spark plugs from a hot engine can cause the spark plugs to seize. This can damage the cylinder head threads.
- Clean the spark plug recess area before removing the spark plug. Failure to do so can result in engine damage due to dirt or foreign material entering the cylinder head, or in contamination of the cylinder head threads. Contaminated threads may prevent proper seating of the new spark plug.
- Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the vehicle. Installing spark plugs of another type can severely damage the engine.
- Turn the ignition OFF.
- If you are replacing the engine right bank (rear) spark plugs, rotate the engine for service access. Refer to Rotating the Engine for Service Access in Engine Mechanical - 3.4L.
- Remove the spark plug wires from the spark plugs. Refer to Spark Plug Wire Replacement .
- Remove the spark plugs from the engine.
