CO–62GR-FE COOLING – COOLING FAN SYSTEM
CO
(g) After the engine is warmed up, check that the fan
operates as shown in the illustration.
HINT:
• The coolant temperature at which the fan starts
operating is approximately 95
C (203F).
• This system can also be checked using the
intelligent tester.
• Select the following menu items: Powertrain /
Engine / Data List / Initial Engine Coolant Temp.

4. ADD ENGINE COOLANT
(a) Tighten the radiator drain cock plug by hand.
(b) Tighten the 2 cylinder block drain cock plugs.
Torque: 13 N*m (130 kgf*cm, 9 ft.*lbf) for
cylinder block drain cock plugs
(c) Remove the air drain cock plug from the water inlet
housing.
(d) Loosen the air drain plug at the top of the radiator 3
or 4 turns.
(e) Add TOYOTA Super Long Life Coolant (SLLC) to
the radiator inlet opening until coolant overflows
from the engine air drain cock hole. Then install the
air drain cock plug to the water inlet housing.
Torque: 13 N*m (130 kgf*cm, 9 ft.*lbf) for air
drain cock plug
(f) Continue to add TOYOTA Super Long Life Coolant
(SLLC) to the radiator inlet opening until coolant
overflows from the radiator air drain hole. Then
close the air drain plug at the top of the radiator.
HINT:
If the coolant level at the radiator inlet opening
drops after squeezing the No. 1 and No. 2 radiator
hoses, add coolant.
(g) Slowly fill the radiator with TOYOTA Super Long Life
Coolant (SLLC).
Standard capacity:
11.3 liters (12.0 US qts, 10.0 Imp. qts)
HINT:
• TOYOTA vehicles are filled with TOYOTA SLLC
at the factory. In order to avoid damage to the
engine cooling system and other technical
problems, only use TOYOTA SLLC or similar
high quality ethylene glycol based non-silicate,
non-amine, non-nitrite, non-borate coolant with
long-life hybrid organic acid technology (coolant
with long-life hybrid organic acid technology
consists of a combination of low phosphates and
organic acids).
• Contact your TOYOTA dealer for further details.
NOTICE:
Never use water as a substitute for engine
coolant.
(h) Slowly pour coolant into the radiator reservoir tank
until it reaches the FULL line.
(i) Squeeze the No. 1 and No. 2 radiator hoses several
times by hand, and then check the level of the
coolant.
If the coolant level is low, add coolant.

(j) Bleed air from the cooling system.
(1) Warm up the engine until the thermostat opens.
While the thermostat is open, circulate the
coolant for several minutes.
HINT:
The thermostat open timing can be confirmed
by squeezing the inlet radiator hose by hand,
and checking when the engine coolant starts to
flow inside the hose.
(2) Maintain the engine speed at 2500 to 3000
rpm.
(3) Squeeze the inlet and outlet radiator hoses
several times by hand to bleed air.
CAUTION:
When squeezing the radiator hoses:
• Wear protective gloves.
• Be careful as the radiator hoses are hot.
• Keep your hands away from the radiator
fan.
NOTICE:
• Make sure that the radiator reservoir still
has some coolant in it.
• If the coolant temperature gauge
indicates an excessive temperature, turn
off the engine and let it cool.
• If there is not enough coolant, the engine
may overheat or be seriously damaged.
• If the radiator reservoir does not have
enough coolant, perform the following: 1)
stop the engine, 2) wait until the coolant
has cooled down, and 3) add coolant
until the coolant is filled to the FULL line.
(k) Stop the engine and wait until the engine coolant
cools down.
(l) Add engine coolant to the FULL line on the radiator
reservoir.
