SPARK PLUG

Spark plugs are selected to suit specific engine design and vehicle operating conditions. The spark plug is designed to
give maximum life and efficient combustion of fuel. The spark gap should be set from 0.024 to 0.028 in. (0.6 to 0.7 mm).
Spark Plug Removal
See General Warnings on page 1-2.
CAUTION
• Before removal and disassembly, clean the engine.
Remove all dirt from plug base in the cylinder head before removing plug. Use a 13/16 in. (21 mm), deep well socket
with ratchet or spark plug wrench to loosen the plug.
Spark Plug Cleaning, Inspection and Repair
Examine the plug (Figure 20-4, Page 20-6). The deposits on the plug base and electrode are an indication of the
correct heat range and efficiency as well as a guide to the general condition of the engine, fuel and air mixture and
ignition system. If all of the above conditions are proper, the spark plug should be a light brown color. There should be
no bridging between the electrode and base. The electrode should not be eroded. Black color, excessive carbon,
and/or a wet plug indicates that the fuel is too rich. White, burned or melted electrodes indicate the fuel is too lean or
pre-igniting. Oily deposits on the plug electrode are an indication of worn rings, valve guides, cylinder wall, etc. Also
examine the spark plug wire. Remove rubber boot and inspect internal spring for damage. Inspect spark plug wire for
damage and be sure spring coil is securely attached to spark plug. See following WARNING.
WARNING
• Remove spark plug wire to avoid accidental start up of the engine when servicing vehicle. To avoid
ignition of fuel and serious personal injury or death, never try to start the engine with plug removed
from engine.
