Downloaded from www.Manualslib.com manuals search engine ENGINE COOLING 6B-7
Coolant Level
To check level, look at “see-through” 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” (2) and “LOW”
(3) marks on reservoir (1).
If coolant level is below “LOW” mark, remove reservoir cap and
add proper coolant to reservoir to bring coolant level up to “FULL”
mark. Then, reinstall cap.
Cooling System Service
Cooling system should be serviced as follows.
1) Check cooling system for leakage or damage.
2) Wash radiator cap and filler neck with clean water by remov-
ing radiator cap when engine is cold.
3) Check coolant for proper level and freeze protection.
4) Using a pressure tester, check system and radiator cap for
proper pressure holding capacity 1.1 kg/cm
2 (15.6 psi, 110
kPa). If replacement of cap is required, use proper cap spec-
ified for this vehicle. WARNING:
To help avoid danger of being burned:
Do not remove reservoir cap while coolant is “boiling”,
and
Do not remove radiator cap while engine and radiator
are still hot.
Scalding fluid and steam can be blown out under pres-
sure if either cap is taken off too soon.
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.
When installing reservoir cap, set arrow marks (4) on
the reservoir and cap as the figure.
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 pres-
sure if cap is taken off too soon.

Radiator
REMOVAL
1) Drain cooling system.
2) Remove radiator shroud.
3) Disconnect water hoses from radiator.
4) With automatic transmission (A/T) vehicle, disconnect addi-
tional two fluid hoses from radiator.
Place some container under radiator to receive A/T fluid
which will flow out when hose is disconnected.
5) Install radiator protection board to between radiator and
cooling fan.
6) Remove radiator after removing two bolts (1).
INSPECTION
If the water side of the radiator is found excessively rusted or cov-
ered with scales, clean it by flushing with the radiator cleaner
compound.
This flushing should be carried out at regular intervals for scale or
rust formation advances with time even where a recommended
type of coolant is used. Periodical flushing will prove more eco-
nomical.
Inspect the radiator cores and straighten the flattened or bent
fins, if any. Clean the cores, removing road grimes and trashes.
Excessive rust or scale formation on the wet side of the radiator
lowers the cooling efficiency.
Flattened or bent fins obstruct the flow of air through the core to
impede heat dissipation.
Radiator flushing interval recommended
Two years
INSTALLATION
Reverse removal procedures.
NOTE:
Refill cooling system with proper coolant referring to
“Coolant” and “Cooling System Flush and Refill” in
this section.
With automatic transmission vehicle, fill A/T fluid up to
specified level. For procedure to check A/T fluid and its
level, refer to “Changing Fluid” in Section 7B.
After installation, check each joint for leakage.
