Spark Plug

Inspection

Poor spark plug condition adversely affects engine
performance. Carefully inspect each spark plug following
the procedure outlined below.

1. Remove the spark plug.
2. Check the plug for dirt and other foreign material.

If the plug is extremely dirty, the fuel and electrical
systems must be checked.

3. If necessary, clean the spark plugs by placing them in

a spark plug cleaning machine for no more than 20
seconds.

4. Check the electrode and insulator for wear and/or

cracking. If there is significant wear or cracking, the
plug must be replaced.

5. Check the gasket for damage. Replace the gasket if

necessary.

6. Measure the insulation resistance with a 500-volt

megaohm meter. Replace the plug if the resistance is
less than the specified value.

Insulation resistance: 50 M

7. Check the spark plug gap. Replace  the spark plug the

if gap is not as specified.

Standard: 1.0–11 mm (0.04–0.043 in)
Limit: 1.3 mm (0.05 in)

D

Do not attempt to adjust the gap of an old spark
plug. Replace the plug and adjust the gap of the
new plug if required.

D

Take care not to damage the spark plug tip during
handling.

8. Tighten the spark plugs to the specified torque.

Torque: 18 N·m (13 lb ft)

Replacement spark plugs

D

Under normal conditions (no problem with the fuel
and/or electrical systems), use replacement spark
plugs with a low heat value (hot-type plug).

D

If insulator and electrode scorching is significant, use
replacement spark plugs plugs with a high heat value
(cold-type plug).
