Coolant Level CheckS7RS0B1606002
WARNING!
To help avoid danger of being burned, do not
remove radiator cap while engine and
radiator are still hot. Scalding fluid and steam
can be blown out under pressure if radiator
cap is taken off too soon.
To check level, lift hood and look at “see-through”
coolant reservoir.
It is not necessary to remove radiator cap to check
coolant level.
When engine is cool, check coolant level in reservoir (1).
A normal coolant level should be between FULL mark
(2) and LOW mark (3) on reservoir (1).
If coolant level is below LOW mark (3), remove reservoir
cap (4) and add proper coolant to reservoir to bring
coolant level up to FULL mark (2).
NOTE
If proper quality antifreeze is used, there is
no need to add extra inhibitors or additives
that claim to improve system. They may be
harmful to proper operation of system, and
are unnecessary expense.
Engine Cooling System Inspection and
Cleaning
S7RS0B1606003
WARNING!
To help avoid danger of being burned, do not
remove radiator cap while engine and
radiator are still hot. Scalding fluid and steam
can be blown out under pressure if cap is
taken off too soon.
1) Check cooling system for leakage or damage.
2) Wash radiator cap and fille r neck with clean water by
removing radiator cap when engine is cold.
3) Check coolant for proper level and freeze protection.
4) Using a pressure tester (1), check system and radiator cap (2) for proper pressure holding capacity.
If replacement of cap is required, use a proper cap
for this vehicle.
NOTE
After installing radiator cap to radiator, make
sure that the ear of cap lines is parallel to
radiator.
Cooling system and radiator cap holding
pressure (for inspection)
110 kPa (1.1 kg/cm2, 15.6 psi)
5) Tighten hose clamps and inspect all hoses. Replace hoses whenever cracked, swollen or otherwise
deteriorated.
6) Clean frontal area of radiator core.
Cooling System DrainingS7RS0B1606004
1) Remove radiator cap.
2) Drain coolant from radiator drain plug (1).
3) After draining coolant, be sure to tighten drain plug (1) securely.

Cooling System Flush and RefillS7RS0B1606005
WARNING!
To help avoid danger of being burned, do not
remove radiator cap while engine and
radiator are still hot. Scalding fluid and steam
can be blown out under pressure if cap is
taken off too soon.
NOTE
For detail of coolant specification, refer to
“Coolant Description”.
1) Remove radiator cap when engine is cool as follows.a) Turn cap counterclockwise slowly until it reaches a “stop” (Do not press down while turning it).
b) Wait until pressure is relieved (indicated by a hissing sound) then press down on cap and
continue to turn it counterclockwise.
2) With radiator cap removed, run engine until upper radiator hose is hot (this shows that thermostat is
open and coolant is flowing through system).
3) Stop engine and drain coolant from radiator drain plug (1).
4) Close radiator drain plug. Add water until system is filled and run engine until up per radiator hose is hot
again.
5) Repeat Steps 3) and 4) several times until drained liquid is nearly colorless.
6) Close radiator drain plug (1) tightly. 7) Remove reservoir (1) and remove cap (2) from
reservoir (1).
8) Pour out any fluid, scrub and clean inside of reservoir with soap and water.
Flush it well with clean water and drain, Reinstall
reservoir.
9) Fill reservoir with coolant up to “Full” level mark (3).
10) Install reservoir cap (2) on reservoir. 11) Fill radiator with coolant up to bottom of radiator filler neck and install radiator cap, making sure that the
ear of cap lines is parallel to radiator.
12) Run engine at idle speed.
13) Run engine until radiator fan motor is operated.
14) Stop engine and wait until engine comes cooled down to help avoid danger of being burned.
15) Add coolant to radiator up to bottom of radiator filler
neck, and install radiator ca p, making sure that the
ear of cap lines is parallel to radiator.
16) Repeat Step 12) through 15).
17) Confirm that reservoir cool ant level is “Full” level
mark (3). If coolant is insu fficient, repeat Step 9) and
10).

• Make sure that air bleed valve (1) of thermostat is clean.
• Check to make sure that va lve seat (2) is free from
foreign matters which would prevent valve from
seating tight.
• Check thermostat seal (3) for breakage, deterioration or any other damage.
• Check thermostatic movement of wax pellet as follows:
a. Immerse thermostat (1) in water, and heat water gradually.
b. Check that valve starts to open at specific temperature.
Temperature at which valve begins to open
80 – 84 °C (176 – 183 °F)
Temperature at which valve become fully open
95 – 97 °C (203 °F)
Va l v e l i ft
More than 8 mm at 95 °C (203 ° F)
If valve starts to open at a temperature substantially
below or above specific temperature, thermostat unit

Fuel Tank Purging ProcedureS7RS0B1706015
WARNING!
• Before starting the following procedure, be sure to observe “Precautions on Fuel
System Service” in order to reduce the risk
or fire and personal injury.
• This purging procedure will not remove all fuel vapor.
Do not attempt any repair on tank using
heat of flame as an explosion resulting in
personal injury could occur.
CAUTION!
Never remain water in fu el tank after washing,
or fuel tank inside will get corrosion.
The following procedure are used for purging fuel tank.
1) After removing fuel tank, remove all hoses, pipes and fuel pump assembly from fuel tank.
2) Drain all remaining fuel from tank.
3) Place fuel tank to flushing area.
4) Fill tank with warm water or tap water, and agitate
vigorously and drain. Repeat this washing until
inside of tank is clean. Replace tank if its inside is
rusty.
5) Completely flush out rema ining water after washing.
Fuel Pump On-Vehicle InspectionS7RS0B1706016
WARNING!
Before starting the following procedure, be
sure to observe “Precautions on Fuel System
Service” in order to reduce the risk or fire
and personal injury.
NOTE
The fuel pressure regulator is incorporated
with the fuel pump assembly so individual
inspection of it is impossible.
1) Remove filler cap and turn ON ignition switch (2).
Then fuel pump operating sound should be heard
from fuel filler (1) for about 2 seconds and stop. Be
sure to reinstall fuel filler cap after checking.
If the check result is not satisfactory, go to “Fuel
Pump and Its Circuit Check in Section 1A”. 2) Turn OFF ignition switch and leave over 10 minutes
as it is.
3) Fuel pressure should be felt at fuel feed hose (1) for about 2 seconds after ignition switch ON.
If fuel pressure is not felt, go to “Fuel Pressure
Check in Section 1A”.

Diagnostic Information and Procedures
Brakes Diagnosis NoteS7RS0B4104001
Road Testing Brakes
Brakes should be tested on dry, clean, smooth and
reasonably level roadway which is not crowned. Road
test brakes by making brake applications with both light
and heavy pedal forces at vari ous speeds to determine if
the vehicle stops evenly and effectively. Also drive
vehicle to see if it leads to one side or the other without
brake application. If it does, check the tire pressure, front
wheel alignment and front suspension attachments for
looseness. See diagnosis table for other causes. Brake Fluid Leaks
Check the master cylinder fl
uid levels. While a slight
drop in reservoir level does result from normal lining
wear, an abnormally low leve l indicates a leak in the
system. In such a case, chec k the entire brake system
for leakage. If even a slight ev idence of leakage is noted,
the cause should be corrected or defective parts should
be replaced.
Substandard or Contaminated Brake Fluid
Improper brake fluid, mineral oil or water in the fluid may
cause the brake fluid to boil or the rubber components in
the hydraulic system to deteriorate.

If deterioration of rubber is evident, disassemble all
hydraulic parts and wash with alcohol. Dry these parts
with compressed air before assembly to keep alcohol out
of the system. Replace all rubber parts in the system,
including hoses. Also, when working on the brake
mechanisms, check for fluid on the linings.
If excessive fluid is found, replace the pads. If master cylinder piston seals
are satisfactory, check for
leakage or excessive heat co nditions. If leakage is not
found, drain fluid, flush with brake fluid, refill and bleed
system.
The system must be flushed if there is any doubt as to
the grade of fluid in the system or if fluid has been used
which contained parts that have been subjected to
contaminated fluid.
