Spark Plug Replacement

Removal Procedure
Caution: 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.
1. Turn OFF the ignition.
2. Remove the spark plug wires from the spark plugs. Refer to
3. Remove the spark plugs from the engine.
Installation Procedure
Caution: It is important to check the gap of all new and reconditioned spark plugs before
installation. Pre-set gaps may have changed during handling. Use a round wire feeler gauge
to be sure of an accurate check, particularly on used plugs. Installing plugs with the wrong
gap can cause poor engine performance and may even damage the engine.
1. Gap the spark plugs to the specifications.
