COOLANT
INSPECTION
HINT:
Check the coolant level when the engine is cold.
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR RESERVOIR
The engine coolant level should be between the ºLOWº and ºFULLº lines.
If low, check for leaks and add ºToyota Long Life Coolantº or equivalent up to the ºFULLº line.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the radiator 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, replace the coolant.
(c) Reinstall the radiator cap.

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 radiator drain plug (on the right side of the ra-
diator lower tank) and engine drain plug (on the left rear
of the cylinder block), and drain the coolant.
(c) Close the drain plugs.
Torque: 25 N´m (250 kgf´cm, 18 ft´lbf) for engine
2. FILL ENGINE COOLANT
(a) Slowly fill the system with coolant.

Use of improper coolants may damage engine cool-
ing system.

Use ºToyota Long Life Coolantº or equivalent and
mix it with plan water according to the manufactur-
er's directions.

Using of coolant which includes more than 50 %
(freezing protection down to ±35°C (±31°F) or 60 %
(freezing protection down to ±50°C (±58°F)) of eth-
ylene±glycol is recommended but not more than 70
%.
NOTICE:

Do not use an alcohol type coolant or plain water
alone.

The coolant should be mixed with plain water (prefer-
ably demineralized water or distilled water).
Capacity:
w/ Oil cooler6.9 litters (7.3 US qts, 6.1 lmp. qts)
w/o Oil cooler6.2 litters (6.5 US qts, 5.4 lmp. qts)
(b) Install the radiator cap.
(c) Start the engine, and bleed the cooling system.
(d) Refill the radiator reservoir with coolant until it reaches the
ºFULLº line.

1. INSPECT WATER PUMP
(a) Visually check the air hole for coolant leakage.
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.

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.

Before using a radiator cap tester, wet the relief valve
and pressure valve with engine coolant or water.

When performing steps (a) and (b) below, keep the
tester at an angle of over 30° above the horizontal.
(a) Using a radiator cap tester, slowly pump the tester and
check that air is coming from the vacuum valve.
Pump speed: 1 push/(3 seconds or more)
NOTICE:
Push the pump at a constant speed.
If air is not coming from the vacuum valve, replace the radiator
cap.
(b) Pump the tester, and measure the relief valve opening
pressure.
Pump speed: 1 push within 1 second
NOTICE:
This pump speed is for the first pump only (in order to close
the vacuum valve). After this, the pump speed can be re-
duced.
Standard opening pressure:
74 ± 103 kPa (0.75 ± 1.05 kgf/cm
2, 10.7 ± 14.9 psi)
Minimum opening pressure:
59 kPa (0.6 kgf/cm
2, 8.5 psi)
HINT:
Use the tester's maximum reading as the opening pressure.
If the opening pressure is less than minimum, 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
