6B-6 ENGINE COOLING
COOLING SYSTEM FLUSH AND REFILL
WARNING:
To help avoid danger of being burned, do not remove radia-
tor cap while engine and radiator cap while engine and ra-
diator are still hot. Scalding fluid and steam can be blown
out under pressure if cap is taken off too soon.
1) Remove radiator cap when engine is cool:
Turn cap counterclockwise slowly until it reaches a “stop”.
(Do not press down while turning it.)
Wait until pressure is relieved (indicated by a hissing sound)
then press down on cap and continue to turn it counterclock-
wise.
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 open radiator drain plug (1) to drain coolant.
4) Close drain plug. Add water until system is filled and run engine
until upper radiator hose is hot again.
5) Repeat Steps 3) and 4) several times until drained liquid is
nearly colorless.
6) Drain system and then close radiator drain plug tightly.
7) Disconnect reservoir tank hose from radiator. Remove reser-
voir tank and pour out any fluid. Scrub and clean inside of tank
with soap and water.
Flush it well with clean water and drain. Reinstall tank and
hose.
8) add 50 / 50 mixture of GOLDEN CRUISER 1200 (Good quality
ethylene glycol anti-freeze) and water to radiator and tank.
Fill radiator to the base of radiator filler neck and reservoir tank
to “FULL” level mark. Reinstall reservoir tank cap.
9) Run engine, with radiator cap removed, until radiator upper
hose is hot.
10) With engine idling, add coolant to radiator until level reaches
the bottom of filler neck. Install radiator cap, making sure that
the ear of cap lines up with reservoir tank hose.

ON-VEHICLE SERVICE
WARNING:
Check to make sure that engine coolant temperature is
cold before removing any part of cooling system.
Also be sure to disconnect negative cord from battery ter-
minal before removing any part.
COOLING WATER PIPES OR HOSES
REMOVAL
1) Drain cooling system.
2) To remove these pipes or hoses, loosen screw on each pipe or
hose clip and pull hose end off.
INSTALLATION
Install removed parts in reverse order of removal procedure, noting
the following.
Tighten each clamp bolt securely.
Refill cooling system with proper coolant, referring to description
on COOLANT of MAINTENANCE.
THERMOSTAT
REMOVAL
1) Disconnect negative cable at battery.
2) Drain cooling system and tighten drain plug.
3) Disconnect thermostat cap (1) from thermostat case (2).

INSPECTION
Immerse temperature sensing part of IAT sensor in water (or ice)
and measure resistance between sensor terminals while heating
water gradually.
If measured resistance doesn’t show such characteristic as shown
in left figure, replace IAT sensor.
INSTALLATION
Reverse removal procedure noting the following.

Clean mating surfaces of IAT sensor and air cleaner case.

Connect IAT sensor coupler securely.
ENGINE COOLANT TEMPERATURE SENSOR
(ECT SENSOR)
REMOVAL
1) Disconnect battery negative cable at battery.
2) Drain coolant referring to Section 6B.
WARNING:
To help avoid danger of being burned, do not remove radia-
tor 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.
3) Disconnect coupler from ECT sensor.
4) Remove ECT sensor from thermostat case.

ENGINE COOLANT TEMPERATURE SENSOR
(ECT SENSOR)
Removal
1) Disconnect battery negative cable at battery.
2) Drain coolant referring to Section 6B.
WARNING:
To help avoid danger of being burned, do not remove ra-
diator 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.
3) Disconnect coupler from ECT sensor.
4) Remove ECT sensor (1) from thermostat case.
Inspection
Immerse temperature sensing part of ECT sensor (1) in water (or
ice) and measure resistance between terminal “A” and “B” while
heating water gradually.
If measured resistance doesn’t show such characteristic as shown
in left figure, replace ECT sensor (1).
Installation
Reverse removal procedure noting the following:

Clean mating surfaces of ECT sensor (1) and thermostat case.

Check O-ring for damage and replace if necessary.

Tighten ECT sensor (1) to specified torque.
Tightening Torque

Connect coupler to ECT sensor (1) securely.

Refill coolant referring to Section 6B.
