Engine Fan
Noise
If
a Tire
Goes
Flat
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
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 he
engine.
It
will
go
away
as
the
fan
clutch disengages.
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 muc11 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 ~naintain 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 yo~~r foot from the
accelerator pedal. Get the c.ehicle under control
by
steering the
way
~OLI 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.
