“VORTEC” 4300 Engine 2.2L Engine 
In  very  cold weather, 
0°F (- 18°C)  or colder, the engine 
coolant heater can help.  You’ll get easier starting  and 
better  fuel economy  during engine  warm-up.  Usually, 
the  coolant heater should  be plugged 
in a minimum of 
four  hours  prior to starting  your  vehicle. 
To use the  coolant  heater: 
1. Turn  off the  engine. 
2. Open  the  hood  and  unwrap the  electrical  cord. 
3. Plug it into a normal,  grounded 110-volt AC outlet.

Plugging  the  cord  into  an  ungrounded  outlet 
could  cause  an electrical  shock.  Also, the  wrong 
kind 
of extension  cord  could.overheat  and  cause 
a  fire. 
You could  be  seriously  injured.  Plug  the 
cord  into 
a properly  grounded  three-prong 
110-volt 
AC outlet. If the  cord  won’t reach,  use a 
heavy-duty  three-prong  extension  cord  rated  for 
at least 
15 amps.

the  positive 
(+) and  negative (-) terminals on 
each  battery. 
1 A CAUTION: 
--- 
Using  a match  near a battery  can  cause  battery 
gas  to  explode.  People  have  been  hurt doing  this, 
and  some  have  been  blinded.  Use 
a flashlight if 
you need  more light. 
Be  sure  the  battery  has  enough  water. You don’t 
need  to  add  water  to  the  Delco Freedom@  battery 
installed  in  every  new 
GM vehicle. But if a 
battery  has  filler  caps,  be  sure  the  right  amount 
of fluid  is  there. If it is low, add  water  to  take 
care 
of that  first.  If  you don’t,  explosive  gas  could 
be  present. 
Battery  fluid  contains  acid  that  can  burn  you. 
Don’t  get  it  on 
you. If you accidentally  get  it  in 
your  eyes or on  your  skin,  flush  the  place  with 
water  and  get  medical  help  immediately. 
5. Check that the jumper cables don’t  have loose or 
missing  insulation. 
If they do, you could  get a shock. 
The  vehicles  could  be  damaged  too. 
Before  you connect  the  cables, 
here are some  basic 
things  you should  know.  Positive 
(+) will  go to 
positive 
(+) and  negative (-) will go to  negative (-) 
or  a metal  engine  part.  Don’t  connect  positive (+) to 
negative 
(-) or you’ll  get  a short  that  would  damage 
the  battery  and  maybe  other  parts 
too.

positive 
(+) cable  to

You will find a coolant temperature gage on your 
vehicle’s  instrument panel. 
If Steam Is Coming  From  Your Engine 
Steam  from an overheated  engine  can  burn  you 
badly,  even if you  just  open  the  hood. Stay  away 
from  the  engine  if you see  or  hear  steam  coming 
from  it. Just  turn  it 
off and  get  everyone away 
from  the  vehicle until  it cools down.  Wait  until 
there  is 
no sign of steam  or coolant  before 
opening  the  hood. 
If  you  keep  driving  when your  engine  is 
overheated,  the  liquids  in  it  can  catch  fire. You or 
others  could  be  badly  burned.  Stop  your  engine  if 
it  overheats,  and  get out  of the  vehicle  until  the 
engine  is cool. 
I NOTICE: 
If your  engine  catches  fire  because  you keep 
driving  with 
no coolant,  your  vehicle can  be 
badly  damaged.  The  costly  repairs  would not  be 
covered  by your  warranty.

If  you get the  overheat  warning  but  see or hear no 
steam,  the  problem  may  not  be too serious. Sometimes 
the engine  can  get  a little  too  hot  when  you: 
Climb  a long  hill on a hot  day. 
Stop  after  high-speed  driving. 
Idle for long  periods  in  traffic. 
Tow  a trailer.  See “Driving  on Grades” in the  Index 
If 
you get  the  overheat  warning with no  sign  of  steam, 
try  this  for  a minute  or 
so: 
1. If you have an air conditioner,  turn it off. 
2. Turn  on  your  heater  to full hot  at the highest  fan 
speed 
and open  the  window  as  necessary. 
3. If you’re in a  traffic  jam, shift to NEUTRAL (N); 
otherwise,  shift  to the highest gear while 
driving 
-- AUTOMATIC OVERDRIVE (,@) 
or  DRIVE (D) for  automatic  transmissions. 
If you  no  longer  have  the  overheat  warning, you can 
drive.  Just  to  be  safe, drive  slower  for  about 
10 minutes. 
If the  warning  doesn’t  come  back  on,  you  can 
drive  normally. 
If the  warning  continues, pull  over,  stop,  and  park  your 
vehicle  right  away. 
If there’s  still  no sign  of steam,  push  the  accelerator  until 
the engine  speed  is  about  twice 
as fast as normal  idle 
speed.  Bring  the  engine speed  back  to  normal  idle  speed 
after  two  or  three  minutes.  Now see 
if the  warning  stops. 
But then, if you still  have  the  .warning, turn ofthe 
engine 
and get everyone  out of the vehicle until  it 
cools down. 
You may decide  not  to lift  the  hood  but  to  get  service 
help  right 
away.

To open the hood,  first pull 
the  handle inside  the vehicle 
on  the  lower  left  side  of the 
instrument  panel. 
Then 
go to  the front  of the  vehicle  and  release the 
secondary hood release.  Lift 
the  hood,  release the  hood  prop from its retainer  and 
put  the  hood  prop  into the slot  in  the  hood. You may

A CAUTION: 
Things  that  burn  can  get on  hot  engine  parts  and 
start 
a fire.  These  include  liquids  like  gasoline, 
oil,  coolant,  brake  fluid,  windshield  washer  and 
other  fluids,  and  plastic  or  rubber. 
You or  others 
could  be  burned.  Be careful  not  to  drop  or  spill
