Drive Belt Inspection
1. Inspect for cracks, fraying, wear or oil adhesion. Replace if
necessary.
The belts should not touch the bottom of the pulley groove.
2. Check drive belt deflection by pushing on the belt midway between pulleys. (H)
3. Adjust if belt deflections exceed the limit.

Changing Engine Oil
WARNING:
IBe careful not to burn yourself, as the engine oil is hot.
I Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com- ponents.
2. Stop engine.
3. Remove dipstick, oil filler cap and drain plug.
4. Drain oil.
5. Install drain plug.
CAUTION:
I Be sure to clean drain plug and install with new washer.
Drain plug:
: 29-39N ×m(3.0 - 4.0 kg-m, 21 - 29 ft-lb)
6. Fill slowly with new oil whilst not exceeding the maximum level.
Oil specification and viscosity:
I See ªRECOMMENDED FLUIDS AND LUBRICANTSº (MA-
17).
Oil capacity (Approximately):
Unit: (Imp qt)
Drain and refill
With oil filter change 6.2 (5-1/2)
Without oil filter change 5.5 (4-7/8)
CAUTION:
IThe refill capacity depends on the oil temperature and
drain time. Use these specifications for reference only.
Always use the dipstick to determine when the proper
amount of oil is in the engine.
7. Install dipstick and filler cap.
8. Start engine. Check area around drain plug and oil filter for any sign of oil leakage.
9. Run engine for a few minutes, then turn it off. After several minutes check oil level again.
10. If necessary, add oil whilst not exceeding the maximum level.
Changing Oil Filter
1. Remove oil filter with a suitable wrench.
WARNING:
Be careful not to burn yourself as engine and oil is hot.

2. Before installing new oil filter, clan the oil filter mounting surfaceon cylinder block and coat the rubber seal of the oil filter with
a little engine oil.
3. Install oil filter. When installing oil filter, screw it in until a slight resistance is
felt, then tighten an additional 2/3 turn or more.
4. Add engine oil.
Refer to Changing Engine Oil.
Changing Engine Coolant
WARNING:
To avoid the danger of being scalded, never attempt to change
the coolant when the engine is hot.
1. Set heater ªTEMPº control lever all the way to ªHOTº position.
2. Remove radiator cap and engine under cover.
3. Disconnect lower radiator hose to drain coolant. Remove reservoir tank, drain coolant, then clean reservoir tank.
Re-install tank temporarily.
4. Remove cylinder block drain plug located at left rear of cylin- der block.
5. Drain coolant and then tighten drain plug securely.
I Apply sealant to the thread of drain
:30-40N ×m (3.1 - 4.1 kg-m, 22.1 - 29.5 ft-lb)
6. Connect lower radiator hose.
7. Fill radiator and reservoir tank with water. Re-install radiator cap and warm up engine.
8. Stop engine and wait until cools down.
9. Drain water.
10. Repeat step 2 through step 9 two or three times, until clear water begins to drain from radiator.
11. Fill radiator with coolant up to the specified level. Follow instructions attached to anti-freeze container for mixing
ratio of anti-freeze to water.Coolant capacity (with reservoir tank): 10.0 (8-3/4 Imp qt)
Slowly pour coolant through coolant filler neck to allow air in
system to escape.

12. Fill reservoir tank up to ªMAXº level, and re-install radiator cap.
13. Run the engine at approximately 2,000 rpm for about oneminute.
14. Stop engine and cool it down, then refill the radiator and the reservoir tank up to the specified level.
Checking Cooling System
CHECKING HOSES
Check hoses for proper attachment, leaks, cracks, damage, loose
connections, chafing and deterioration.
CHECKING RADIATOR CAP
Apply pressure to radiator cap by means of a cap tester to see if it
is satisfactory. Radiator cap relief pressure:78-98kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2, 11 - 14 psi)
CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system by means of a tester to check
for leakage. Testing pressure:157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher than the specified pressure may cause radiator dam-
age.
Checking and Replacing fuel filter and Draining
Water
Be careful not to spill fuel in engine compartment. Place a rag
to absorb fuel.
REPLACING FUEL FILTER
1. Remove fuel filter sensor and drain fuel.

2. Remove fuel filter, using a suitable tool.
3. Wipe clean fuel filter mounting surface on fuel filter bracket andsmear a little fuel on rubber seal of fuel filter.
4. Screw fuel filter on until a slight resistance is felt, then tighten and additional more than 2/3 turn.
5. Install fuel filter sensor to new filter.
6. Bleed air from fuel line. Refer to Bleeding Fuel System in EC section.
7. Start engine and check for leaks.
DRAINING WATER
1. Loosen drain cock and drain water.
Loosening drain cock 4 to 5 turns causes water to start drain-
ing. Do not remove drain cock by loosening it excessively. If water does not drain properly, move the priming pump up and
down.
2. Bleed air. Refer to section EC for fuel system bleeding instructions.
Cleaning and Replacing Air Cleaner Filter (Dry
paper type)
Clean or replace element more often under dusty driving condi-
tions.
