Explanation:
If the fan fails to run after the temperature
of the coolant reaches the starting
temperature of the fan, check the fuse of
the fan for blowing out, and replace the
INTRODUCTION OF DRIVING
fuse if necessary. If this does not work,
find out other causes.
The RPM of the fan is independent to that
of the engine and shifting to a lower gear
will not increase the cooling effect of the
fan. Therefore, need not to shift to a lower
gear when the engine runs smoothly and
its speed does not fall obviously when
climbing.
