ON−VEHICLE INSPECTION
1. REMOVE 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.
2. INSPECT RADIATOR CAP
NOTICE:
If the radiator cap has contaminations,always rinse it with
water.
Using a radiator cap tester, pump the tester and measure the
relief valve opening pressure.
Standard opening pressure:
74 − 103 kPa (0.75 − 1.05 kgf/cm
2, 10.7 − 14.9 psi)
HINT:
Use the tester’s maximum reading as the opening pressure.
If the opening pressure is less than standard, replace the radia-
tor cap.
3. INSPECT COOLING SYSTEM FOR LEAKS
(a) Fill the radiator with coolant and attach a radiator cap tes-
ter.
(b) Warm up the engine.
(c) Pump it to 118 kPa (1.2 kgf/cm
2, 17.1 psi), and check that
the pressure does not drop.
If the pressure drops, check the hoses, radiator or water pump
for leaks. If no external leaks are found, check the heater core,
cylinder block and head.
4. REINSTALL RADIATOR CAP

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.

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.

moves smoothly and quietly.
If necessary, replace the water pump.

(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.
