Anti-freeze Coolant Mixture Ratio
The engine cooling system is filled at the factory with a high-
quality, year-round, anti-freeze coolant solution. The anti-freeze
solution contains rust and corrosion inhibitors. Therefore, addi-
tional cooling system additives are not necessary.
CAUTION:
When adding or replacing coolant, be sure to use only an
ethylene glycol anti-freeze with the proper mixture ratio. See
the following examples:

The use of other types of coolant solutions may damage
your cooling system.

Checking Drive Belts
1. Inspect for cracks, fraying, wear or oil. If necessary, replace
with a new one.
2. Inspect drive belt deflections by pushing midway between
pulleys.
Adjust if belt deflections exceed the limit.

Changing Engine Coolant
WARNING:
To avoid being scalded, never change the coolant when the
engine is hot.
Ð DRAINING ENGINE COOLANT Ð
1. Move heater ``TEMP'' control lever all the way to ``HOT''
position.
lMake sure that air condition switch is ``OFF''.
2. Open radiator drain plug at the bottom of radiator, and
remove radiator cap.
3. Remove reservoir tank, drain coolant, then clean reservoir
tank. Install it temporarily.
Be careful not to allow coolant to contact drive belts.
4. Remove cylinder block drain plug.
Ð FLUSHING COOLING SYSTEM Ð
5. Install and then tighten radiator drain plug and cylinder block
drain plug securely.
6. Open air relief plug.
7. Fill radiator with water and close air relief plug and radiator
cap.
8. Run engine and warm it up sufficiently.
9. Race engine 2 or 3 times under no-load.
10. Stop engine and wait until it cools down.
11. Repeat step 2 through step 10 until clear water begins to
drain from radiator.
12. Drain water.
Ð REFILLING ENGINE COOLANT Ð
lApply sealant to the thread of drain plug.

13. Open radiator cap and air relief plug.
14. Fill radiator with coolant up to specified level.
Follow instructions attached to anti-freeze container for mix-
ing ratio of anti-freeze to water.
For coolant mixture ratio, refer to MA-14.

15. Close air relief plug.
16. Remove reservoir tank, drain coolant, then clean reservoir
tank.
17. Install reservoir tank and fill it with coolant up to ``MAX'' level
and then install radiator cap.
18. Run engine and warm it up sufficiently.
19. Race engine 2 or 3 times under no-load.
20. Stop engine and cool it down, then add coolant as neces-
sary.
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:
Standard
78-98kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2, 11 - 14 psi)
Limit
59-98kPa
(0.59 - 0.98 bar, 0.6 - 1.0 kg/cm
2,9-14psi)
Pull the negative-pressure valve to open it. Check that it closes
completely when released.

CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system with cap tester to check for
leakage.
Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher pressure than the specified value may cause damage
to the radiator.
Checking Fuel Lines
Inspect fuel lines and tank for improper attachment and for leaks,
cracks, damage, loose connections, chafing and deterioration.
If necessary, repair or replace malfunctioning parts.
CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end
is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.
Changing Fuel Filter
WARNING:
Before removing fuel filter, release fuel pressure from fuel
line.
1. Remove fuse for fuel pump.
2. Start engine.
3. After engine stalls, crank engine two or three times to make
sure that fuel pressure is released.
4. Turn ignition switch OFF and install fuse for fuel pump.
5. Loosen fuel hose clamps.
6. Replace fuel filter.
lBe careful not to spill fuel or engine compartment. Place
a shop towel to absorb fuel.
lUse a high-pressure type fuel filter. Do not use a syn-
thetic resinous fuel filter.
lWhen tightening fuel hose clamps, refer to ``Checking
Fuel Lines'', MA-18.

Changing Air Cleaner Filter (Viscous paper
type)
The viscous paper type filter does not need cleaning
between renewals.
Changing Engine Oil
WARNING:
lBe careful not to burn yourself, as the engine oil is hot.
lProlonged 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. Remove drain plug and oil filler cap.
3. Drain oil and refill with new engine oil.
Oil grade: API, SG or SH
Viscosity: See ``RECOMMENDED FLUIDS AND
LUBRICANTS'', MA-13.

CAUTION:
lBe sure to clean drain plug and install with new washer.
Drain plug:

lUse recommended engine oil.
lThe refill capacity changes depending on the oil tem-
perature and drain time, use these values as a reference
and be certain to check with the dipstick when changing
the oil.
4. Check oil level.
5. Start engine and check area around drain plug and oil filter
for oil leakage.
6. Run engine for a few minutes, then turn it off. After several
minutes, check oil level.
