See your Warranty Book before  using your  vehicle  for 
racing 
or other  competitive  driving. 
NOTICE: 
If you  use  your vehicle  for racing  or other 
competitive  driving, your  engine  may  use  more 
oil  than 
it would  with  normal use. Low oil  levels 
can damage the  engine. Be sure  to check  the oil 
level  often  during racing or other  competitive 
driving  and keep  the level  at  or  near  the  upper 
mark  on the  engine 
oil dipstick.  You may  need  to 
add  oil.  See  “Adding  Oil”  under “Engine”  in 
the  Index. 
Engine  Coolant  Heater 
(Canada  Only) 
The engine  coolant heater  is located  on the  driver’s side 
of  the  engine  under the manifold.  The electrical cord is 
attached  to  the generator bracket  assembly, between the 
generator  and the windshield washer fluid tank. 
In  very  cold  weather, 
0 OF (- 18 O 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.

If the LOW OIL LEVEL message on the Driver 
Information Center comes on,  it means  you  need  to 
check  your engine oil level right  away. For more 
information, see “Driver Information Center” in the 
Index.  You should check your engine oil level regularly; 
this  is an added reminder. 
It’s 
a good idea to check  your engine oil level every time 
you  get fuel. In order to  get an accurate reading,  the oil 
must  be warm  and  the vehicle must be on level ground. 
The engine oil dipstick  is 
next to  the coolant surge 
tank.  The dipstick handle  is 
a  round, yellow loop. 
Turn  off the engine and give  the oil a few minutes to 
drain  back into the oil pan.  If  you  don’t, the oil dipstick 
might  not show  the actual level. 
Checking  Engine  Oil 
Pull  out the dipstick  and  clean it with  a  paper  towel  or  a 
cloth,  then  push  it back  in all the  way.  Remove  it again, 
keeping the tip down. 
When to Add Engine  Oil 
If the oil  is  at or below  the  ADD  mark,  you’ll  need  to 
add at least  one quart  of oil.  But  you  must  use  the  right 
kind. This part explains  what  kind  of oil to use.  For 
crankcase  capacity, see “Capacities  and  Specifications” 
in the Index.

Downloaded from www.Manualslib.com manuals search engine I NOTICE: 
Don’t  add  too  much oil. If your  engine  has so 
much  oil  that  the  oil  level  gets  above  the  upper 
mark  that  shows  the  proper  operating  range, 
your  engine  could  be  damaged. 
The engine oil  fill  cap  is on 
top of the right valve rocker 
arm  cover. 
Be  sure  to fill it  enough to put the level somewhere in 
the  proper  operating  range. Push the dipstick all the  way 
back  in when  you’re  through. 
What Kind of Engine Oil to Use 
Look for two things: 
GM4718M 
The Corvette engine requires  a special oil meeting 
GM Standard GM4718M. Oils meeting this Standard 
may be identified  as synthetic. However, not all 
synthetic oils will meet this GM Standard.  You 
should look for and use  only  an oil that meets 
GM 
Standard GM47  18M. 
FNOTICE: 
If you  use  oils  that  don’t  have  the GM4718M 
Standard  designation,  you  can  cause  engine 
damage  not  covered  by  your  warranty.
