Installation
1. Install rubber cushions on both sides of radiator
bottom.
2. Install radiator assembly with hose, taking care not to
damage the radiator core with a fan blade.
3. Connect reserve tank hose (4).
4. Install lower fan guide (3).
5. Connect radiator inlet hose and outlet hose to the
engine.
6. Connect oil cooler hose (1) to automatic
transmission.

7. Connect battery ground cable.
8. Pour engine coolant up to filler neck of radiator, and
up to MAX mark of reserve tank.

Important operation (in case of 100% engine coolant
change) procedure for filling with engine coolant.
f
Remove radiator cap.
f
Fill with engine coolant (EC) to the radiator filler
neck.
f
Fill with EC to the “MAX” line on the reservoir.
f
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.
f
By EC temperature gauge reading make sure that
the thermostat is open.
f
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.
f
Replenish EC to the “MAX” line on the reservoir and
leave as it is until the engine gets cool.
f
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 3,000
rpm.
f
Should water running noise be heard, repeat the
same procedure from the beginning.

(7) Drive Belt
The drive belt adjustment is not required as automatic
drive belt tensioner is equipped.
Inspection
Check drive belt for wear or damage, and replace with a
new one as necessary.
Installation
Install cooling fan assembly and tighten bolts/nuts to the
specified torque.
Torque : 22 N·m (16 lb ft) for fan pulley and fan
bracket.
Torque : 7.5 N·m (66.4 lb in) for fan and clutch
assembly.
NOTE: Fan belts for 6VD1 Gasoline Engine mounted on
98MY Rodeo(UE) have been brought into one. As a
result, the rotating direction of a fan belt is opposite to the
direction of cooling fan for 93 to 97MY 6VD1 with no
interchangeability.
Therefore, incorrect installation of a fan may cause the air
for cooling to flow in the opposite direction, this resulting
in the poor performance of the air-conditioner and a rise
temperature in engine cooling water.
