Use  a mixture  of one-half clean water (preferably 
distilled)  and  one-half 
DEX-COOL TM (orange-colored, 
silicate-free) antifreeze that meets  GM Specification 
6277M, which  won’t  damage aluminum  parts. Use 
GM Engine Coolant Supplement (sealer) (GM 
Part 
No. 3634621) with any complete coolant change. 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  mix  will.  Your  vehicle’s  coolant warning 
system  is set  for  the  proper  coolant mix. With 
plain  water  or the  wrong  mix,  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 mix of clean 
water  and 
DEX-COOL TM (orange-colored. 
silicate-free) antifreeze. 
NOTICE: 
If you  use  an  improper  coolant  mix,  your  engine 
could  overheat  and  be  badly  damaged.  The 
repair  cost  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. 
If  you  have to add coolant more  than four times a year, 
have  your dealer 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.

LOW 
COOLANT 
When  your  engine is cold, check  the  dipstick on the  cap 
of the coolant  recovery  tank. The  coolant  level should 
be at COLD, or a little  higher.  When  your engine  is 
warm, the level  on the  dipstick should  be  up  to HOT, 
or  a little  higher.  If  this 
light comes  on,  it 
means  you’re 
low on engine 
coolant. 
Your  Corvette  also has a high  fill reservoir  located at 
the  right rear 
of the  engine  compartment. 
If the  recovery  tank is  very low or empty,  also  add 
coolant  to the  high  fill reservoir. 
To add  coolant  at 
the  high  fill reservoir,  see  “Engine  Overheating”  in 
the  Index.

Downloaded from www.Manualslib.com manuals search engine Adding Coolant  to  the Recovery  Tank 
If you  need more coolant,  add the  proper  mix at the 
coolant recovery tank, but only  when  your  engine  is 
cool.  If the tank  is 
very low or empty,  also add  coolant 
to  the  coolant  high fill reservoir.  See  “Engine 
Overheating”  in the  Index for  information. 
.JTION: 
r 
Turning the  coolant high fill reservoir  pressure  cap 
when  the  engine  and radiator  are  hot 
can allow 
steam and scalding  liquids  to blow out and  burn 
you  badly.  Never 
turn the  pressure  cap -- even a 
little 
-- when  the  engine  and  radiator  are  hot. 
Add coolant  mix  at the recovery tank,  but  be careful  not 
to spill  it. 
I 
CAUTION: 
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. 
For  complete  drain, flush  and  refill  of the  engine, 
contact  your Chevrolet dealer  or  the  procedure  may be 
found  in a  Chevrolet  Corvette Service Manual. 
To 
purchase  a service  manual,  see “Service  and  Owner 
Publications”  in  the  Index.

Downloaded from www.Manualslib.com manuals search engine Coolant High Fill Reservoir  Cap 
NOTICE: 
Your  coolant  high  fill  reservoir  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. 
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  pre-set  temperature. 
Power  Steering  Fluid 
When to Check  Power  Steering Fluid 
It  is  not  necessary  to regularly  check  power  steering 
fluid  unless  you  suspect  there  is  a  leak  in  the system or 
you  hear  an  unusual  noise. 
A fluid  loss in this system 
could indicate  a  problem. Have the system inspected 
and  repaired.
