jacking GMC SIERRA 1995 Owners Manual

Engine Fan Noise
Your 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 every day
driving conditions the fan is spinning slower and 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 as the clutch more fully 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 partially disengages.
You may also hear this fan noise when you start the engine. It will go away
as the
fan clutch partially 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, 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.

Tighten Clockwise Tightening Sequence
t
40
Tighten the
nuts firmly in a criss-cross sequence as shown. Rotate the wheel
wrench clockwise.
A CAUTION:
Incorrect wheel nuts or improperly tightened wheel nuts can
cause the wheel to become loose and even come
off. This could
lead to an accident. Be sure to use the correct wheel nuts.
If you
have to replace them, be sure to get the right kind.
Stop somewhere
as soon as you can and have the nuts tightened
with
a torque wrench to the proper torque.
For proper torque, see “Wheel Nut Torque” in the Index.
Put the wheel trim back on.
For vehicles with plastic wheel
nut caps, tighten the caps until they are
finger tight, then tighten them an additional one-half turn
with the ratchet
and wheel wrench.
Remove any wheel blocks.
Remember, the jack, jacking equipment and tire must be properly stored
in
their original storage position before you begin driving again. The next part,
“Storing the Tire and Jack,”
will show you how.
