COOLING SYSTEM
Coolant Level
Check the coolant level and replenish the radiator reserve
tank as necessary.
If the coolant level falls below the “MIN” line, carefully
check the cooling system for leakage. Then add enough
coolant to bring the level up to the “MAX” line.
Engine coolant Filling up procedure
1. Make sure that the engine is cool.
Warning:
When the coolant is heated to a high temperature, be
sure not to loosen or remove the rediator cap.
Otherwise you might get scalded by hot vapor or
boiling water.
To open the radiator cap, put a piece of thick cloth on
the cap and loosen the cap slowly to reduce the
pressure when the coolant has become cooler.
2. Open rediator cap pour coolant up to filler neck
3. Pour coolant into reservoir tank up to “MAX” line
4. Tighten radiator cap and start the engine. After idling
for 2 to 3 minutes, stop the engine and reopen radiator
cap. If the water level is lower, replenish.
5. After replenish the coolant tighten radiator cap, warm
up the engine at about 2000 rpm. Set heater
adjustment to the highest temperature position, and let
the coolant circulate also into heater water system.
6. Check to see the thermometer, continuously idling 5
minutes and stop the engine.
7. When the engine has been cooled, check filler neck
for water level and replenish if required. Should
extreme shortage of coolant is found, check the
coolant system and reservoir tank hose for leakage.
8. Pour coolant into the reservoir tank up to “MAX” line.

Engine Warm-Up
After completing the required maintenance procedures,
start the engine and allow it to idle until it is warm.
Check the following:
1. Engine idling speed.
2. Engine noise level.
3. Engine lubricating system and cooling system.
Carefully check for oil and coolant leakage.

Mixing ratio
Check the specific gravity of engine coolant in the cooling
system temperature ranges from 0C to 50C using a
suction type hydrometer, then determine the density of the
engine coolant by referring to the table.
NOTE: The LLC is 50% at all environment in order to prevent
the corrosion of cooling system parts.

Installation
1. Install radiator assembly, taking care not to damage the
radiator core.
2. Install the radiator assembly.
3. Connect reserve tank hose.
4. Connect radiator inlet hose and outlet hose.
5. Pour engine coolant up to filler neck of radiator, and up to
MAX mark of reserve tank.
Important operation (in case of 100% engine coolan
t
change) procedure for filling with engine coolant.
Remove radiator cap.
Fill with engine coolant (EC) to the radiator filler neck.
Fill with EC to the "MAX" line on the reservoir tank.
Start the engine with the radiator cap removed and bring to
operating temperature by running engine at 2,500 - 3,000
rpm for 30 minutes.
By EC temperature gauge reading make sure that the
thermostat is open.
If air bubbles come up to the radiator filler neck, replenish
with EC. Repeat until the EC level does not drop any further.
Install the radiator cap and stop the engine.
Replenish EC to the "MAX" line on the reservoir tank and
leave as it is until the engine gets cool.
After the engine gets cool, start the engine and make sure
there is no water running noise heard from the heater core
while the engine runs at 3000 rpm.
Should water running noise be heard, repeat the same
procedure from the beginning.
