What to Use 
Use a mixture of one-half clean water (preferably 
distilled) and one-half 
DEX-COOL@ coolant which 
won’t damage aluminum parts.  If you use this mixture, 
you  don’t need to add anything  else. 
Adding  only  plain  water  to  your  cooling  system 
can  be  dangerous.  Plain  water,  or  some  other 
liquid  like  alcohol,  can  boil  before  the  proper  coolant  mixture  will. Your  vehicle’s  coolant 
warning  system  is  set  for  the  proper  coolant 
mixture.  With  plain  water  or  the  wrong  mixture, 
your  engine  could  get  too  hot  but  you wouldn’t 
get  the  overheat  warning.  Your engine  could 
catch  fire  and  you or  others  could  be  burned. 
Use 
a 50/50 mixture  of clean  water  and 
DEX-COOL@ coolant. 
J 
NOTICE: 
If you  use an  improper  coolant  mixture,  your 
engine  could  overheat  and  be  badly  damaged. 
The  repair  cost  wouldn’t  be  covered  by your 
warranty.  Too much  water  in the  mixture  can 
freeze  and  crack  the  engine,  radiator,  heater  core 
and  other  parts. 
If  you  have to add coolant more  than four times a  year, 
have your retailer check your  cooling system. 
NOTICE: 
If you use the  proper  coolant,  you  don’t  have  to 
add  extra  inhibitors  or  additives  which claim  to 
improve  the  system.  These  can  be  harmful.

Checking Coolant 
The  engine  coolant  reservoir is located on the driver’s 
side 
of the  vehicle,  above the air cleaner. 
When your  engine 
is cold, the coolant  level  should  be 
at 
FULL COLD, or  a little  higher. When your  engine 
is warm, the level  should be above  the 
FULL COLD 
mark, or a little  higher. 
Adding  Coolant 
If this  light  comes on,  it 
means you’re low on 
engine  coolant. 
If you  need more  coolant, add the  proper DEX-COOL@ 
coolant  mixture at  the  coolant  recovery tank. 
- 
Turning the  radiator pressure cap  when the 
engine  and  radiator  are  hot can  allow  steam and 
scalding  liquids to  blow out and  burn  you  badly. 
With  the coolant  recovery  tank, you  will  almost 
never  have 
to add  coolant  at the radiator.  Never 
turn  the radiator  pressure  cap 
-- even a little -- 
when  the engine  and  radiator  are  hot.

1 Add coolant mixture  at  the recovery tank, but  be careful 
~ not  to  spill it. 
~ 
You  can be burned if you  spill  coolant  on  hot 
engine  parts. Coolant  contains  ethylene  glycol, 
and 
it will  burn  if the  engine  parts  are  hot 
enough.  Don’t  spill  coolant  on 
a hot  engine. 
_- - 
When you replace  your radiator  pressure  cap, a GM cap 
is  recommended. 
Radiator  Pressure Cap 
NOTICE: 
Your  radiator  cap is a 15 psi (105 kPa) 
pressure-type  cap and  must  be  tightly  installed  to 
prevent  coolant  loss  and possible  engine  damage 
from  overheating.  Be 
sure the arrows  on the cap 
line  up with  the overflow  tube on the  radiator 
filler  neck. 
Thermostat 
Engine coolant temperature  is controlled  by a thermostat 
in  the  engine  coolant system.  The thermostat 
stops the 
flow of coolant  through the  radiator  until  the  coolant 
reaches  a preset temperature. 
When  you replace  your thermostat,  a 
GM thermostat 
is recommended.

Part C: Periodic  Maintenance 
Inspections 
Listed  below  are inspections  and  services  which  should  be 
performed  at  least  twice  a  year  (for  instance,  each  spring  and  fall). 
You should  let  your retailerk  service  department 
or other  qualified  service  center do these jobs. Make  sure 
any  necessary  repairs  are  completed  at once. 
Proper procedures  to perform these  services  may be 
found  in  a service  manual. 
See “Service  and Owner 
Publications”  in the  Index. 
Steering,  Suspension  and  Front  Drive  Axle 
Boot  and  Seal  Inspection 
Inspect  the  front and  rear  suspension  and  steering  system 
for  damaged,  loose  or missing  parts,  signs  of  wear  or lack 
of  lubrication.  Inspect  the  power  steering  lines  and  hoses 
for  proper  hook-up,  binding,  leaks,  cracks,  chafiig, etc. 
Clean  and  then  inspect  the  drive axle boot  seals  for 
damage,  tears  or leakage.  Replace  seals  if necessary. 
Exhaust  System  Inspection 
Inspect  the  complete exhaust  system.  Inspect  the  body  near 
the  exhaust  system.  Look for broken,  damaged,  missing  or 
out-of-position  parts  as well  as  open  seams,  holes,  loose 
connections  or other  conditions  which  could  cause a  heat  build-up 
in the  floor  pan or could  let  exhaust  fumes  into 
the  vehicle.  See “Engine  Exhaust” 
in the  Index. 
Engine  Cooling  System  Inspection 
Inspect  the hoses  and  have  them  replaced  if  they  are 
cracked,  swollen  or deteriorated.  Inspect  all pipes,  fittings 
and  clamps;  replace  as  needed.  Clean  the  outside  of  the 
radiator  and 
air conditioning  condenser. To help  ensure 
proper  operation,  a  pressure  test  of the  cooling  system  and 
pressure  cap 
is recommended  at least  once  a  year. 
Throttle  System  Inspection 
Inspect  the  throttle  system  for interference  or binding,  and  for 
damaged  or missing  parts.  Replace  parts  as  needed.  Replace 
any  components  that  have  high  effort  or excessive  wear. 
Do not  lubricate  accelerator  and  cruise  control  cables. 
Brake  System  Inspection 
Inspect  the  complete system.  Inspect  brake  lines  and 
hoses  for  proper  hook-up,  binding,  leaks,  cracks, 
chafing,  etc.  Inspect disc  brake  pads for wear and  rotors 
for  surface  condition.  Also inspect  drum brake  linings 
for  wear and  cracks.  Inspect  other  brake parts, including 
drums,  wheel cylinders,  calipers,  parking brake, etc. 
Check parking brake  adjustment.  You may  need 
to have 
your brakes  inspected more  often if your  driving  habits 
or  conditions  result  in frequent  braking.
