When  using  concentrated  washer fluid, 
follow  the manufacturer’s instructions  for 
adding  water. 
Don’t 
mix water  with  ready-to-use  washer 
fluid.  Water  can cause  the solution  to freeze 
and  damage your  washer  fluid tank  and 
other  parts  of the washer  system.  Also, 
water  doesn’t  clean 
as well as washer  fluid. 
Fill  your  washer  fluid  tank only 
314 full 
when  it’s  very  cold.  This allows  for 
expansion,  which  could  damage the  tank 
if 
it is  completely  full. 
Don’t  use  radiator antifreeze  in your 
windshield  washer. 
It can damage  your 
washer  system  and paint. 
Cruise Control  (Option) 
With cruise  control,  you can maintain a  speed of about 
25 mph (40 km/h) or  more  without keeping  your  foot on 
the accelerator.  This can really help on long trips.  Cruise 
control  does  not work at speeds below about 
25 mph 
(40 km/h).

The coolant  level  should  be  at  or  above FULL COLD.  If 
it isn’t,  you may  have  a leak  in the  radiator 
hoses, heater 
hoses,  radiator,  water  pump  or somewhere  else  in  the 
cooling  system.

NOTICE: 
Engine  damage  from  running  your  engine 
without  coolant  isn’t  covered  by  your  warranty. 
If there  seems  to  be  no  leak,  with the  engine  on  check  to 
see if the  electric  engine  fan  is running. If the  engine  is 
overheating,  the  fan  should  be  running. If it isn’t,  your 
vehicle  needs  service. 
How to Add Coolant  to  the  Coolant  Surge 
Tank 
If you haven’t  found a problem  yet,  but  the  coolant  level 
isn’t  at 
FULL COLD, add  a 50/50 mixture  of clean 
water (preferably  distilled)  and a  proper  antifreeze at the 
coolant  surge  tank, but be sure  the cooling  system, 
including  the  coolant  surge  tank  pressure  cap, 
is cool 
before  you do it. 
(See “Engine  Coolant”  in the  Index  for 
more  information  about  the proper  coolant  mix.)

NOTICE: 
In  cold  weather,  water  can  freeze  and  crack  the 
engine,  radiator,  heater  core  and  other  parts. 
So use  the  recommended  coolant. 
1. You can  remove  the coolant  surge tank pressure  cap 
when  the  cooling  system,  including  the coolant surge 
tank  pressure  cap and  upper radiator  hose, 
is no 
longer  hot. Turn  the  pressure  cap  slowly about 
one-quarter  turn  to  the left and then stop. 
5-17  
     
        
        Page 201 of 340
4. With  the  coolant  surge  tank  pressure  cap off, start the 
engine  and  let  it run  until 
you can feel  the  upper 
radiator  hose  getting  hot.  Watch  out for the engine 
fan. 
By 
this time,  the coolant  level  inside  the coolant 
surge  tank  may  be  lower. 
If the  level  is lower,  add 
more  of the  proper 
mix to  the  coolant  surge  tank 
until  the  level reaches 
FULL COLD, or just  above 
the  small  cylinder  at  the  base 
of the  opening. 
5. Then  replace  the  pressure  cap.  Be  sure  the  pressure 
cap  is tight.

What to Use 
Use a mixture  of one-half clearz water (preferably 
distilled) and one-half  antifreeze  that meets 
“GM 
Specification 182SM,” which  won’t damage  aluminum 
parts.  You can also  use a recycled coolant  conforming  to 
GM Specification 1825M with a complete coolant flush 
and refill. Use 
GM Engine  Coolant Supplement  (sealer) 
with  any complete coolant flush and refill. 
If you use 
this mixture,  you don’t  need to add anything  else. 
I 
I NOTICE: 
If you use an improper coolant mix, your engine 
could overheat  and be badly  damaged. The 
repair cast  wouldn’t  be  covered by your 
warranty. 
Too much  water  in the mix can freeze 
and  crack  the engine,  radiator, heater core and 
other parts.

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,  an  AC@ thermostat 
is recommended. 
Power Steering Fluid

How To Check  Power  Steering Fluid 
When the  engine compartment is  cool, unscrew the  cap 
and wipe the  dipstick with 
a clean  rag.  Replace the  cap 
and completely tighten  it. Then  remove  the cap  again 
and look  at the  fluid  level  on the  dipstick. 
The level should  be  at the FULL COLD mark.  Add 
enough  fluid  to bring the  level up to the mark. 
A fluid loss in this system  could  indicate  a problem. 
Have  the system inspected  and repaired. 
What to Add 
Refer to the Maintenance  Schedule  to determine what 
kind 
of fluid  to  use. See “Recommended Fluids  and 
Lubricants” 
in the Index. 
I NOTICE: 
When  adding  power  steering  fluid  or  making  a 
complete  fluid  change,  always use  the  proper 
fluid.  Failure  to  use  the  proper  fluid  can  cause 
leaks  and  damage  hoses  and  seals.

may  fall below freezing, use  a fluid that has sufficient 
protection against freezing. 
To Add 
Open the cap labeled 
WASHER 
FLUID OmY. 
Add washer fluid until the 
tank  is  full.
