ENGINE COOLING

6. Disconnect the reserve tank hose(4) from radiator.
7. Remove bracket(5).

8. Lift up and remove the radiator assembly with hose,

taking care not to damage the radiator core with a fan
blade.

9. Remove rubber cushions on both sides at the bottom.

Inspection

Radiator Cap

Measure the valve opening pressure of the pressurizing
valve with a radiator filler cap tester.
Replace the cap if the valve opening pressure is outside
the standard range.

Valve opening pressure kPa (psi) 88.3 

 117.7

(12.8 

17.1)

Cap tester: 5–8840–0277–0
Adapter: 5–8840–2603–0
Check the condition of the vacuum valve in the center of
the valve seat side of the cap. If considerable rust or dirt is
found, or if the valve seat cannot be moved by hand, clean
or replace the cap.

Valve opening vacuum kPa (psi) 1.96 

 4.91

(0.28

Radiator Core

1. A bent fin may result in reduced ventilation and

overheating may occur. All bent fins must be
straightened. Pay close attention to the base of the fin
when it is being straightened.

2. Remove all dust, bugs and other foreign material.

Flushing the Radiator

Thoroughly wash the inside of the radiator and the engine
coolant passages with cold water and mild detergent.
Remove all signs of scale and rust.

Cooling System Leakage Check

Use a radiator cap tester to force air into the radiator
through the filler neck at the specified pressure of 196 kPa
(28.5 psi) with a cap tester:

D

Leakage from the radiator

D

Leakage from the coolant pump

D

Leakage from the water hoses

D

Check the rubber hoses for swelling.

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. Install bracket (6) and support the radiator upper tank

with the bracket (5) and secure the radiator.

4. Connect reserve tank hose (4).
5. Install lower fan guide (3).
6. Connect radiator inlet hose and outlet hose to the

engine.

7. Connect oil cooler hose (1) to automatic

transmission.

8. Connect battery ground cable.
9. Pour engine coolant up to filler neck of radiator, and

up to MAX mark of reserve tank.

111RS001

Important operation (in case of 100% engine coolant
change) procedure for filling with engine coolant.

1. Make sure that the engine is cool.

2. Open radiator 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.

WARNING: WHEN THE COOLANT IS HEATED TO A
HIGH TEMPERATURE, BE SURE NOT TO LOOSEN
OR REMOVE THE RADIATOR 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.

5. After tightening 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 thermostat has opened through

the needle position of water thermometer,
conduct a 5–minute idling again 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 cooling system and reservoir tank hose
for leakage.

8. Pour coolant into reservoir tank up tp “MAX” line.

ENGINE COOLING

Drive Belt and Cooling Fan

Drive Belt and Associated Parts

015RW005

Legend

(1) Crankshaft Pulley
(2) Generator
(3) Power Steering Pump

(4) Water Pump and Cooling Fan Pulley
(5) Idle Pulley
(6) Tension Pulley
(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 (2.2 Kg·m/16 lb ft) for fan pulley
and fan bracket.

Torque : 10 N·m (1.0 Kg·m/88.5 lb in) for fan and
clutch assembly.

NOTE: Fan belts for 6VE1 Gasoline Engine mounted on
98MY (UX) have been brought into one.  As a result, the
rotating direction of a fan belt is opposite to the direction
of cooling fan for 92 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.
