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.
