Engine coolant
The coolant level is sati sfactory if it is between the “F” and “L” lines on
the reservoir when the engine is cold.

Low
If the level is on or below the “L”
line, add coolant up to the “F” line.
(P. 341)
■ Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant
with long-life hybrid organic acid technology.
U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water. (Minimum temperature: -31 F [-35 C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Minimum temperature: -44 F [-42 C])
For more details about engine coolant, contact your Scion dealer.
■ 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 Scion dealer test the cap and check for
leaks in the cooling system.

tory if it is between the “F” and

Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the ai r conditioning system on to
check that the radiator cooling fan operates and to check
for coolant leaks from the radiator or hoses.
The fan operates when the air conditioning system is turned on
immediately after a cold start. Confirm that the fan is operating by
checking the fan sound and air flow. If it is difficult to check these,
turn the air conditioning system on and off repeatedly.
(The fan may not operate in freezing temperatures.)
If the fan is not operating:
Stop the engine immediately and contact your Scion
dealer.
If the fan is operating: Have the vehicle inspected at the nearest Scion dealer.

CAUTION
■
To prevent an accident or injury when inspecting under the hood of
your vehicle
● If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injuries such as burns.
● Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fan and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
● Do not loosen the radiator cap and the coolant reservoir cap while the
engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE
■When adding engine coolant
Wait until the engine has cooled down before adding coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot engine too
quickly can cause damage to the engine.
■ To prevent damage to the cooling system
Observe the following precautions:
● Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
● Do not use commercially available coolant additives.
