6 Start the engine and turn the air
conditioning system on to check
that the radiator cooling fan oper-
ates and to check for coolant leaks

by checking the fan sound and air flow. If it
is difficult to check these, turn the air con-
ditioning system on and off repeatedly.
(The fan may not operate in freezing tem-
peratures.)
