OIL AND FILTER
INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SH Energy−Conserving II multigrade en-
gine oil or ILSAC multigrade engine oil.
Recommended viscosity is as shown in the illustra-
tion, with SAE 5W −30 being the preferred engine oil.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ”L” and ”F” marks on the di\
p-
stick.
If low, check for leakage and add oil up to ”F” mark.
3. REMOVE OIL PRESSURE SWITCH, AND INSTALL OIL
PRESSURE GAUGE
4. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
5. CHECK OIL PRESSURE Oil pressure:
At idle
29 kPa (0.3 kgf/cm
2, 4.3 psi) or more
At 3,000 rpm
245 − 490 kPa (2.5 − 5.0 kgf/cm
2, 36 − 71 psi)
6. REMOVE OIL PRESSURE GAUGE AND REINSTALL OIL PRESSURE SWITCH
(a) Remove the oil pressure gauge.
(b) Apply adhesive to 2 or 3 threads of the oil pressure switch.
Adhesive:
Part No. 08833 −00080, THREE BOND 1344,
LOCTITE 242 or equivalent
(c) Reinstall the oil pressure switch.
7. START ENGINE AND CHECK FOR LEAKS

REPLACEMENT
CAUTION:
Prolonged and repeated contact with mineral oil will result
in the removal of natural fats from the skin, leading to dry-
ness, irritation and dermatitis. In addition, used engine oil
contains potentially harmful contaminants which may
cause skin cancer.Care should be taken, therefore, when
changing engine oil to minimize the frequency and length
of time your skin is exposed to used engine oil. Protective
clothing and gloves that cannot be penetrated by oil should
be worn. The skin should be thoroughly washed with soap
and water, or use water−less hand cleaner, to remove any
used engine oil. Do not used gasoline, thinners, or sol-
vents.In order to preserve the environment, used oil and
used oil filters must be disposed of only at designated dis-
posal sites.
1. DRAIN ENGINE OIL
(a) Remove the oil filler cap.
(b) Remove the oil drain plug, and drain the oil into a contain-
er.
2. REPLACE OIL FILTER
(a) Using SST, remove the oil filter. SST 09228−44011
(b) Check and clean the oil filter installation surface.
(c) Apply clean engine oil to the gasket of a new oil filter.
(d) Lightly screw the oil filter into place, and tighten it until the
gasket contacts the seat.
(e) Using SST, tighten it an additional 3/4 turn. SST 09228−44011
3. FILL WITH ENGINE OIL
(a) Clean and install the oil drain plug with a new gasket.
Torque: 25 N·m (250 kgf·cm, 18 ft·lbf)
(b) Fill with new engine oil. Oil grade:
See step 1 in oil pressure check

INSPECTION
HINT:
Inspect these items when the engine is cold.
1. INSPECT DRIVE BELT (See page CH−2)
2. INSPECT AIR FILTER
(a) Visually check that the air cleaner element is not exces- sively dirty, damaged or oily.
If necessary, replace the air cleaner element.
(b) Clean the element with compressed air. First blow from the inside thoroughly, then blow off the
outside of the element.
3. REPLACE AIR FILTER
Replace the air cleaner element with a new one.
4. REPLACE SPARK PLUGS (See page IG−1 )
5. REPLACE ENGINE OIL AND OIL FILTER (See page LU−2)
6. REPLACE ENGINE COOLANT (See page CO−2)
7. INSPECT CHARCOAL CANISTER (See page EC−6 )
8. REPLACE GASKET IN FUEL TANK CAP (See page
EC−6)
9. INSPECT FUEL LINES AND CONNECTIONS (See page EC−6)
10. INSPECT EXHAUST PIPES AND MOUNTINGS
Visually inspect the p ipes, hangers and connections for severe
corrosion, leaks or damage.
11. ADJUST VALVE CLEARANCE (See page EM−4)
