Engine Fan Noise
This vehicle has a clutched engine cooling fan. When
the clutch is engaged, the fan spins faster to provide
more air
to
cool the engine. In most everyday driving
conditions, the clutch is
not
fully engaged. This
improves
fuel
economy and reduces fan noise. Under
heavy vehicle loading, trailer towing and/or high outside
temperatures, the
fan
speed increases when the clutch
engages.
So
you may hear an increase
in
fan noise. This
is normal and should
not
be mistaken as the
transmission slipping or making extra shifts.
It
is merely
the cooling system functioning properly. The fan
will
slow down when additional cooling is
not
required and
the clutch disengages.
You
may also hear this fan noise when you start the
engine.
It
will
go away
as
the
fan clutch disengages.
If
a
Tire Goes Flat
It’s
unusual for
a
tire
to
“blow out” while you’re driving,
especially if
you
maintain your tires properly. If air goes
out of a tire, it’s much more likely
to
leak
out
slowly.
But
if
you
should ever have a “blowout,” here are
a
few
tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot
off
the
accelerator pedal and grip the steering wheel firmly.
Steer
to
maintain lane position, and then gently brake to
a
stop well
out
of the traffic lane.
A
rear blowout, particularly on a curve, acts much
like
a
skid and may require the same correction you’d
use
in
a
skid.
In
any rear blowout, remove your foot from
the
accelerator pedal. Get the vehicle under control by
steering the way you want
the
vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake
to
a
stop
--
well
off
the road
if
possible.
If
a
tire goes flat, the
next
part shows how
to
use your
jacking equipment
to
change a
flat
tire safely.
