Start the engine and turn the air 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 any authorized
Toyota dealer or repairer, or another duly qualified and
equipped professional.
If the fan is operating:
Have the vehicle inspected at the nearest authorized
Toyota dealer or repairer, or another duly qualified and
equipped professional.
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 fans and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.

Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
Do not use any coolant additive.
Do not loosen the coolant reservoir cap
while the engine and radiator are hot.
