ENGINE COOLING SYSTEM INSPECTION
AND SERVICE
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.
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 (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.
Cooling system and radiator cap holding pressure (for
inspection)
: 110 kPa (1.1 kg/cm
NOTE:
After installing radiator cap to radiator, make sure that
the ear of cap lines is parallel to radiator.
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 FLUSH AND REFILL

1) Remove radiator cap when engine is cool.
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.
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.
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).
