When trouble arises
7
eAdd coolant if necessary
Water can be used in an emergency if
coolant is unavailable.
fStart the engine and turn the air co nditioning system on to check that
the radiator cooling fan operates and to check again for coolant leaks
from the radiator core or hoses
The fan operates when the air conditioning system is turned on immediately after a
cold start. Confirm that the fan is operat ing by checking the fan sound and air flow.
If it is difficult to check them, turn the air conditioning system ON and OFF repeat-
edly.
(The fan may not operate in freezing temperatures)
g If the fan is not operating:
Stop the engine immediately and contact your Toyota dealer
If the fan is operating:
Have the vehicle inspected at the nearest Toyota dealer
WARNING
⬛Before taking measures
Do not remove the radiator cap if the coolant is hot. The radiator cap is under
the pressure of the coolant. Therefore, steam or hot water may spurt out of it,
causing serious injury such as burns.
⬛To prevent an accident or injury when inspecting under the hood of your
vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
⚫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.
⚫Keep hands and clothing (especially a tie, a scarf or a muffler) away from the
fan and belts. Failure to do so may caus e the hands or clothing to be caught,
resulting in serious injury.
⚫Do not loosen the radiator cap an d the coolant reservoir cap while the
engine and radiator are hot. High te mperature steam or coolant could spray
out.
