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.

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 Lexus dealer.
If the fan is operating:
Have the vehicle inspected at the nearest Lexus dealer.
