“TOYOTA Genuine 50/50 Pre-mixed
Super Long Life Coolant BLUE” is a mix- ture of 50% coolant and 50% deionized
water. (Minimum temperature: -35°C
[-31°F])
For more details about engine coolant,
contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
■If the coolant level drops within a
short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain
cock and water pump.
If you cannot find a leak, have your Toyota dealer test the cap and check for
leaks in the cooling system.
Check the radiator and condenser
and clear away any foreign objects.
If either of the above parts is
extremely dirty or you are not sure
of their condition, have your vehicle
inspected by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.

■When the engine is hot
Do not remove the engine coolant reservoir cap. ( P.364)
The cooling system may be under
pressure and may spray hot coolant if the cap is removed, causing serious
injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor
straight antifreeze. The correct mix-
ture of water and antifreeze must be used to provide proper lubrication,
corrosion protection and cooling. Be
sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to
prevent it from damaging parts or
paint.

sound and air flow. If it is difficult to
check these, turn the air conditioning system on and off repea tedly. (The fans
may not operate in freezing tempera-
tures.)

Toyota retailer or Toyota author-
ized repairer, or any reliable
repairer.

nearest any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.

the hood, do not open the hood
until the steam has subsided. The engine compartment may be very
hot.
●Keep hands and clothing (espe-
cially a tie, a scarf or a muffler)
away from the fans and belts. Fail-
ure to do so may cause the hands or clothing to be caught, resulting in
serious injury.

caps while the engine and radiator
are hot. High temperature steam or coolant
could spray out.

has cooled down sufficiently. Adding
cool coolant to a hot engine too
quickly can cause damage to the engine.

Observe the following precautions:
●Avoid contaminating the coolant
with foreign matter (such as sand or
dust etc.).
●Do not use any coolant additive.
