Highlander 4WD V6-3.5L (2GR-FE) (2008)
(e) Add TOYOTA Super Long Life Coolant (SLLC) to the radiator inlet opening until coolant overflows from the engine air drain cock hole.
Then tighten the air drain cock plug to the water inlet housing.
Torque: 13 Nm (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.
Torque: 1.5 Nm (15 kgf-cm, 13 in-lbf) for air drain plug
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:
w/o Trailer Towing System
w/ Trailer Towing System
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.
NOTE: 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 reservoir 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.
