5. Remove the spark plugs.
NOTICE: A piece of rubber fuel line works well to remove the
plug from the cylinder head after it is loosened.
6. If the electrodes are extremely sooty, clean carefully with a
wire brush.
7. Inspect for cracks in the porcelain insulator. If cracks are vis-
ible, spark plugs must be replaced.
8. Determine the condition of the spark plugs by checking the
gap with a feeler gauge. The gap must be within the range
indicated in the illustration.
• If both spark plugs are within the range, reinstall them.
• If the gap on either spark plug is not within the correct
range, replace both spark plugs with new ones. Always
replace spark plugs in pairs.
9. Apply a light coat of anti-seize compound to the spark plug
threads.
10. To avoid altering the gap or damaging the threads, carefully insert the spark plugs in the engine and tighten to
16.2 - 23.6 ft.lb (22 - 32 Nm).
11. Insert the ignition coils. Replace the serrated lock nuts with new ones. Install the bolts, washers and serrated lock
washers and tighten to 5.9 - 7.4 ft.lb (8 - 10 Nm).
12. Reconnect the wire harness to the ignition coils.
13. Reconnect the power supply to the engine.
14. Clear the service counter for the service light. See Diagnostics on page 71.
15. Test drive the vehicle.

COOLING SYSTEM

The vehicle's cooling system components that require periodic maintenance consists of:
• radiator
• coolant reservoir

• coolant

• cooling fan
• hoses and clamps
See SCHEDULED MAINTENANCE CHART on page 46 for maintenance requirements and intervals.
Coolant
See RECOMMENDED LUBRICANTS AND FLUIDS on page 48 for recommended coolants and mixing ratio.
The use of incompatible coolant will cause insufficient cooling of the engine. Combining different coolants can trigger
a chemical reaction and cause loss of effectiveness. The recommended coolants listed have been tested for compati-
bility by the engine manufacturer. Verify compatibility of any coolant not recommended in the list before use.
An incorrect mixing ratio reduces the cooling capacity. When topping off coolant, do not change the mixing ratio. Use
the same coolant through the year in the mixing ratio specified on page 48.
