th e "Add" line. Rem ember,  your engine  may use more oil when it is new . 
• The best time  to  check  the engine  oil level is when  the oil is warm,  such  as 
during  a fuel stop. First,  wait  about  5 minutes  for the  oil to drain back  to 
the  oil pan,  Then,  pull out the dipstick,  wipe

Some 
dipSlicks  have "Add" and "Full" lines , Others are  marked "Add! Qt" 
and "Operaling  Range." In all cases, keep the oil level above the 
"Add" line. Push· the dipstick  back down  all the  way  after  taking  the

• If you  check  the oil level  when  the oil is cold, do no t  run  the engine  first. The cold  oil wilJ not drain  back to the  pan  fast enough  to give  a true  oil level. 
Engine Oil Additives 
There  are many extra engine  oil additives  (or helpers)  for sale.  Your  engine should 
not  need  these  extra additives if you use SE-quality or SF·quality engine  oil and 
change 
it as  suggested. If you  think  your engine  has .an oil-related  problem, talk 
to  your  authorized  dealer. 
If needed, your dealer  can provide  you with  a tested 
and  approved  oil additive  called "GM Engine Oil Supplement." 
AUTOMATIC TRANSAXLE FLUID RECOMMENDATIONS 
Use the Proper Fluid Use only automatic  transmission  fluid labe led DEXRON-®II. You  can buy  this 
fluid  from  your Chevrolet  dealer or 
othe~,'service outlets. 
Check the Fluid Level with care Check  the automatic  transmission  fluid level at each engine  oil change.  Before 
checking  the fluid  level,  set the  parking  brake and then  start  the engine.  AppJy 
the  regular  brakes and then 
'mov e the shift lever  through  all of the gear  ranges, 
ending  in 
"P '·(Park).  You must check  the fluid  level with the engine  funning  at 
slow idle and  the car  level.

Downloaded from www.Manualslib.com manuals search engine NOTICE: You cannot read the correct fluid level if you have just driven the car for a long time at high speed, in city traffic in hot weather, or if the car has been pulling a trailer. Wait. until the fluid has cooled down (about 30 minutes). 
Remove the dipstick  located on the  driver's  side forward of the cowl.  Carefully 
touch  the wet  end of the dipstick  to find  out if the fluid is cool,  warm  or hot.  Wipe 
it  clean  and push  it back  in until  the cap  seats.  Pull 
out the dipstick  and read  the 
fluid  level. 
• If it felt cool or warm (about room temperature), the level should be 
between the dimples above the "Full" mark. 
• If it was too hot to hold. the level should be at or in the hatched area. 
Add just  enough DEXRON-®n fluid to fill the  transaxle. It takes  only 0.5 liter 
(one pint)to raise  the level  from "Add" to "Full" with a hot  transaxle. 
Do not overfill  the transaxle.  Overfilling  can cause  foaming  and loss of fluid,  which 
could  result in transaxle  damage. 
Automatic Transaxle Drain Intervals 
Change the transmission  fluid and change  the filter  (or clean  the screen)  as 
outlined  in Section 
A of the  Maintenance  Schedule folder. 
ELECTRIC FAN 
CAUTION: Keep hands, tools, and clothing away from the angine cooling fan to help prevent personal injury. This fan is electric and can come on whether or not the engine  is running.  The fan can start automatically in response to a heat sensor when the ignition is  in the "Run" position. 
ENGINE COOLING SYSTEM 
The  coolant  recovery  system is standard.  The coolant in the radiator  expands  with 
heat,  and the overflow  collects in the  recovery  tank.  When the system  cools down, 
the  coolant 
is drawn  back into the radiator. 
The  cooling  system was filled  at the  factory  with a quality  coolant  that meets 
GM Specification  1899-M. The cooling  system is designed  to use  coolant  (a mixture 
of water  and ethylene  glycol antifreeze)  rather than plain  water.  The coolant 
solution  should be used year round. It has many  advantages,  such as: 
• provides freezing protection  down to _37°C, (-34°P) 
• 
provides  boiling protection  up to 128QC, (262°P) 
• 
protects  against rust and corrosion in the cooling  system, 
• maintains  the proper  engine  temperature  for efficient  operation  and emission 
control,  and 
• allows proper  operation of the coolant  temperature  light (or gage). 
See  Section  A of  the  Maintenance  Schedule folder to find  out when  the coolant 
must 
be replaced. 
COOLING SYSTEM CARE 
Check  the cooling  system at regular  intervals,  such as during  fuel stops. You 
usually  do not  need  to remove  the radiator  cap to check  the coolant  level. Lift 
the  engine  hood and look  at the "see  through" coolant  recovery  tank. When  the 
engine 
is cold,  the coolant  level -should  be at or slightly  above the "Full Cold" 
mark on the tank.  When  the engine  has fully  warmed  up, the level  should  be at ')r slightly  below the "Full Hot" mark on the  tank. If the coolant  level is low,

Cooling System Service 
The cooling  syste m should be serviced  at the  intervals  specifi ed inSection A of 
the Maintenan ce Sch edule  fold er as  follows: 
I. W ash the radiatqr cap .and filler  neck with clean  water. See step J of "Coolant 
Replacement"  to remove rapiator cap.  . 
2. C hec k the coolant  level in  the radiator and have  it tes ted for  freeze  proteCtion . Add·· ethylene  gly col antifreeze, if needed, to· m aintain freeze protecti on at -37'C(-34'F), 
3~ Have ·the coOlin-g  sys tem and radiat or cap tested fo r a press ure  capacity  of 
105 kPa  (15  psi) . If a repl acement cap is  needed"Hse an AC ca'p,or an 
equivalent · cap,  designed fOl:  coolant  recovery system ·s and spe cified  for your model; 
4. Tighten  all radiator hose clamps and heater hose clamps and inspect  an  hose s.

eplace  the  hose s if  they  are  swollen, "checked" or otherwise  worn . 
NOTICE: Take care when tightenjng·the hose clemps at tMI radiator. Overtightening COUld. bend or collapse .the radiator fittings. 
5.  Clean the front. of the  radiator core and air condit ioning condenser  to  re m ove 
dirt and oth er·objects. Al so  clean  the auxiliary  engine oil andlor transmission -fluid ' cooler  if the vehicle  has them. 
Coolant, Replacement 
At the interval s specified  in Section  A of  the  Maintenance Schedule  folder,  flu sh 
a
nd refill the cool ing system  as follows : 
1. Remove the·radiat or·cap when the engin e is ·cool : 
• 
Turn . t he cap s lowly  to  the  len until ·it reaches a " stop. " Do  not press down while  turning  the cap. 
•  'Wait until any  rem aining press ure  (indicated  by a hissing  sound) is 
reliev ed.  then press down on  the cap an d continue  turning it t(j the left. 
CAUTION:· To help ~lVoid the danger of being ,burned, do not remove the radiator cap while the angine and radiator are still hot s.c.lding flutd and steam can be bk)wn out under pressure if the·cap is taken off.too soon. 
2. Whe n the cap is re m oved, run the eng ine until the upper radiator hose  is hot.
