lgnition System
1. Inspect the electrodes and ceramic insulator for:
Spark Plug lnspection
. lmproper gap. Oil-fouling. Carbon deposits. Cracked centerelectrode insulatorDamagedgaskei
Burned or worn electrodes may be caused by:
. Advanced ignition timing. Loose spark plug
. Plug heat range too low. Insufficient cooling
Fouled plugs may be caused bY:. Retarded ignition liming. Oil in combustion chamber. Incorrect spark plug gap
. Plug heat range too high. Excessive rdling'low speed running
. Clogged air cleaner element. Deteriorated ignition coil or ignition wires
81881, 818C5 engine:
. Adjust the gap wjth a suitable gapping tool, and
replace the plug if the center electrode is rounded
as shown below.
Electrode Gap:
Standard 'l .1 ; r mm {0.043 ; ooa in)

a Do not adjust the gap ol a platinum tip plug;
replace the spark plug it the center electrode is
rounded or if the gap is not within the specifi-
cattons.
Electrode Gap:

Apply a small quantity ot anti-seize compound to the
plug threads belore installing the plugs.
Screw the plugs into the cylinder head tinger tight,
then torque them to 18 N.m (1 .8 kgf.m, 13lbf.ft).

Fan Motor Test
Disconnect the 2P connector from the fan motor.
Test the motor by connecting battery power to the
B terminal, and ground to the A termlnal.
lf the fan motor fails to run smoothly, replace it.
NOTE: The illustration shows the radiator fan.
Radiator Fan Switch Test
NOTE: Bleed air from the cooling system after installing
the radiator fan switch (see section 10)
1. Remove the radiator fan switch from the thermostat
housing.
2. Suspend the radiator fan switch in a container ol
coolanl as shown.
Heat the coolant and check engine coolant tempera
ture with a thermometer.
Check the continuity between the A and B terminals
according to the table:

Install the radiator cap loosely.
Install the battery.
Start the engine and let it run until it warms up (the
radiator fan comes on at least twice).
Turn off the engine. Check the level in the radiator,
and add Honda All Season Antifreeze/Coolant Type2 if needed.
Put the radiator cap on tightly, then run the engine
again and check for leaks.
