REASSEMBLY
1. M/T:
INSTALL OIL COOLER TO LOWER TANK
Clean the O−ring contact surface of the lower tank.
2. M/T:
CHECK CORE PLATE FOR DAMAGE
HINT:
If the sides of the core plate groove are deformed, reas-
sembly of the tank will be impossible. Therefore, first cor-
rect any deformation with pliers.
Water leakage will result if the bottom of the core plate
groove is damaged or dented. Therefore, repair or re-
place if necessary.
3. M/T:
INSTALL TANK
Install a new O−ring and the tank.
HINT:
Clean the tank and core plate.
Take out any twists.
4. M/T:
INSTALL TANK PLATE
Insert new tank plates from both ends in the direction of the
arrows. Firmly set the tank plates in the core plate.

The points shown in the illustration cannot be staked with
the SST. Use pliers and be careful not to damage the core
plates.
6. M/T:
CHECK FOR WATER LEAKS
(a) Tighten the drain plug.
(b) Plug the inlet and outlet pipes of the radiator with SST
SST 09230 − 01010 (09231 − 00060, 09231 − 01010,
09231 − 01020, 09231 − 01030)
(c) Using a radiator cap tester, apply pressure to the radiator.
Test pressure:
147 kPa (1.5 kgf/cm
2, 21 psi)
(d) Check for water leaks.
HINT:
On radiators with resin tanks, these is a clearance between the
core plate and tank plate where a minute amount of air will re-
main, giving the appearance of an air leak when the radiator is
submerged in water. Therefore, before performing the water
leak test, first swirl the water around in the radiator until all air
bubbles disappear.
7. M/T:
PAINT TANK PLATE
HINT:
If the water leak test checks out okay, allow the radiator to dry
completely and then paint the tank plate.

COOLANT
INSPECTION
1. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
TANK
The engine coolant level should be between the
”LOW” and ”FULL” lines, when the engine is cold.
If low, check for leaks and add engine coolant up to the ”FULL”
line.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap from the water outlet.
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
(b) There should not be any excessive deposits of rust or
scale around the radiator cap or radiator filler hole, and
the coolant should be free from oil.
If excessively dirty, clean the coolant passages and replace the
coolant.
(c) Reinstall the radiator cap.

− COOLING (5VZ−FE)COOLANT
1996 TOYOTA T100 (RM449U)
REPLACEMENT
1. DRAIN ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
(b) Loosen the drain plugs, and drain the engine coolant.
(c) Close the drain plugs.
2. FILL ENGINE COOLANT
(a) Slowly fill the system with engine coolant.
Use a good brand of ethylene−glycol base engine
coolant and mix it according to the manufacturer’s
directions.
Using engine coolant which includes more than 50
% ethylene−glycol (but not more than 70 %) is rec-
ommended.
NOTICE:
Do not use an alcohol type engine coolant.The engine cool-
ant should be mixed with demineralized water or distilled
water.

(b) Install the radiator cap.
(c) Start the engine, and bleed the cooling system.
(d) If necessary, refill engine coolant into the reservoir tank

− COOLING (5VZ−FE)WATER PUMP
1996 TOYOTA T100 (RM449U)
INSPECTION
1. INSPECT WATER PUMP
(a) Visually check the air hole and water hole for coolant leak-
age.
If leakage is found, replace the water pump.
If engine coolant has leaked onto the timing belt, replace the
timing belt.
(b) Turn the pulley, and check that the water pump bearing
moves smoothly and quietly.
If necessary, replace the water pump.
2. INSPECT FLUID COUPLING
(a) Remove the 4 nuts and fan from the fluid coupling.
(b) Check that the fluid coupling is not damaged and that no
silicon oil leaks.
If necessary, replace the fluid coupling.
3. INSPECT FAN PULLEY BRACKET
(a) Check the turning smoothness of the fan pulley.
If necessary, replace the pulley bracket.
(b) Reinstall the fan to the fluid coupling with the 4 nuts.

INSPECTION
INSPECT THERMOSTAT
HINT:
Thermostat is numbered according to the valve opening tem-
perature.
(a) Immerse the thermostat in water and heat the water grad-
ually.
(b) Check the valve opening temperature and valve lift.
Valve opening temperature:
80 − 84°C (176 − 183°F)
Valve lift: At 95°C (203°F): 8.5 mm (0.335 in.) or more
If the valve opening temperature and valve lift are not within
