HINT: TOYOTA vehicles are filled with TOYOTA Super Long Life Coolant at the factory. In order to avoid damage to the engine cooling
system and other technical problems, only use TOYOTA Super Long Life Coolant 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).
NOTICE: Never use water as a substitute for engine coolant.
(d) Squeeze the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant. If the coolant level drops below the
"B" line, add TOYOTA Super Long Life Coolant to the B line.
(e) Bleed air from the cooling system.
(1) Warm up the engine until the thermostat opens. While the thermostat is open, allow the coolant to circulate for several minutes.
HINT: The thermostat opening timing can be confirmed by squeezing the inlet radiator hose by hand, and sensing vibrations when the engine
coolant starts to flow inside the hose.
CAUTION: When squeezing the radiator hose:
-
Wear protective gloves.
-
Be careful as the radiator hose is hot.
-
Keep your hands away from the radiator fan.
(2) Run the engine intermittently (5 seconds run at 3000 rpm and 45 seconds idle) for 7 minutes or more. (repeat 8 cycles or more)
(3) Squeeze the inlet and outlet radiator hoses several times by hand to bleed air.
CAUTION: When squeezing the radiator hose:
-
Wear protective gloves.
-
Be careful as the radiator hose is hot.
-
Keep your hands away from the radiator fan.
(f) After the engine cools down, check the coolant level is between "LOW" and "FULL" line.
If the coolant level is below the LOW line, repeat all of the procedures above.
If the coolant level is above the FULL line, drain coolant so that the coolant level is between the FULL and LOW line.
