See your Warranty Book before  using your  Corvette  for 
racing  or  other competitive  driving. 
NOTICE: 
If you  use  your Corvette 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.

are  on  properly.  Then, just pull the hood down and  close 
it  firmly. 
Engine Oil 
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.

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 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. 
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.

What Kind of Oil to Use 
Look for  two things: 
GM4718M 
The  Corvette  engine  requires a special  oil  meeting 
GM Standard GM47 18M. 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. 
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. I I 
1 NOTICE: I 
If you  use  oils  that  don’t  have  the GM4718M 
Standard  designation,  you  can  cause  engine 
damage  not  covered 
by your  warranty.
