BACK DOOR DAMPER STAY REMOVAL
1. REMOVE ROOF SIDE INNER GARNISH
(See page BO±60)
2. REMOVE DAMPER STAY LOWER END FROM BODY
3. REMOVE DAMPER STAY UPPER END FROM BACK
DOOR
NOTICE: When handling the damper.
wDo not disassemble the damper because the cylinder is
filled with pressurized gas.
wIf the damper is to be replaced, drill a 2.0±3.0 mm
(0.079±0.118 in.) hole in the bottom of the removed
damper cylinder to completely release the high±pressure
gas before disposing of it.
wWhen drilling, chips may fly out so work carefully.
wThe gas is colorless, odorless and non±toxic.
wWhen working, handle the damper carefully. Never score
or scratch the exposed part of the piston rod, and never
allow paint or oil to get on it.
wDo not turn the piston rod and cylinder with the damper
fully extended.

COOLANT CHECK
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR
RESERVOIR
The engine coolant level should be between the ºLOWº and
ºFULLº lines.
If low, check for leaks and add engine coolant up to the
ºFULLº line.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION: To avoid the danger of being burned, do not remove
the radiator cap while the engine and radiator are still hot, as
fluid and steam can be blown out under pressure.
(b) There should not be any excessive deposits of rust or scale
around the radiator cap or radiator filler hole, and the coolant
should be free from oil.
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap. EG±330

Simple Method:
(a) Quickly race the engine 5 times to 4,000 rpm.
(b) Remove the spark plug.
(c) Visually check the spark plug.
If the electrode is dry...OK
If the electrode is wet...Proceed to step 4
(d) Reinstall the spark plug.
3. REMOVE SPARK PLUGS
Using a 16 mm plug wrench, remove the 6 spark plugs.
4. VISUALLY INSPECT SPARK PLUGS
Check the spark plug for thread damage and insulator dam-
age.
If abnormal, replace the spark plug.
Recommended spark plug:
ND
PK16R11
NGK
BKR5EP11
5. INSPECT ELECTRODE GAP
Maximum electrode gap for used spark plug:
1.3 mm (0.051 in.)
If the gap is greater than maximum, replace the spark plug.
Correct electrode gap for new spark plug:
1.1 mm (0.043 in.)
NOTICE: If adjusting the gap of a new spark plug, bend only
the base of the ground electrode. Do not touch the tip. Never
attempt to adjust the gap on the used plug.
6. CLEAN SPARK PLUGS
If the electrode has traces of wet carbon, allow it to dry and
then clean with a spark plug cleaner.
Air pressure:
Below 588 kPa (6 kgfVcm
2, 85 psi)
Duration:
20 seconds or less
HINT: If there are traces of oil, remove it with gasoline before
using the spark plug cleaner.
7. REINSTALL SPARK PLUGS
Torque: 18 NVm (180 kgfVcm, 13 ftVlbf)

IGNITION COIL INSPECTION
NOTICE: ºColdº and ºHotº in the following sentences express
the temperature of the coils themselves. ºColdº is from ±105C
(145F) to 505C (1225F) and ºHotº is from 505C (1225F) to 1005C
(2125F).
1. REMOVE NO.3 TIMING BELT COVER
2. DISCONNECT IGNITION COIL CONNECTORS
3. INSPECT PRIMARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between the
positive (+) and negative (±) terminals.
Primary coil resistance:
Cold
0.54 ± 0.84

Hot
0.68 ± 0.98

If the resistance is not as specified, replace the ignition coil.
