To prevent damaging the iridium center electrode, use a wire type feeler gauge to check the spark plug gap. Do not adjust the spark plug gap. If the gap is out of specification, replace with a new one. |
|
|
Check the gap between the center and side electrodes with a wire type feeler gauge.
SPARK PLUG GAP: 1.0 - 1.1 mm (0.039 - 0.043 in)
Make sure that the 1.2 mm (0.05 in) diameter feeler gauge does not insert between the gap.
If the gauge can be inserted into the gap, replace the plug with a new one.

Check the coolant level of the reserve tank with the engine running at normal operating temperature.
The level should be between the "UPPER" and “LOWER" level lines.
If necessary, add recommended coolant.
RECOMMENDED ANTIFREEZE:
Pro Honda HP coolant or an equivalent high quality ethylene glycol antifreeze containing silicate free corrosion inhibitors
Remove the filler cap and fill the "UPPER" level line with 1 : 1 mixture of distilled water and antifreeze.
Install the filler cap.
