.The gauge moves a little while
turning a corner or speeding up.
. The gauge takes a few seconds
to stabilize after the ignition is
turned on, and goes back to
empty when the ignition is
turned off.
Engine Coolant
Temperature Gauge
This gauge shows the engine
coolant temperature.
If the gauge pointer moves into the
red zone, the engine is too hot.
This reading indicates the same
thing as the warning light. It means
that the engine coolant has
overheated. If the vehicle has been
operating under normal driving
conditions, pull off the road, stop the
vehicle, and turn off the engine as soon as possible. See
Engine
Overheating 0230 for more
information.
Transmission
Temperature Gauge
This gauge will display when the
transmission is experiencing
abnormal temperatures.
As the transmission begins to
overheat, the gauge fills to the right.
The Transmission Temperature
Gauge monitors all aspects of the
transmission. Elevated transmission
temperatures may not be reflected
in the Transmission Fluid
Temperature cluster display gauge.
Messages will display to indicate the
severity of the overheating. As the
gauge fills up there will be a
reduction in vehicle performance. Once full, the transmission is
overheated and a message to stop
safely will display. Do not drive the
vehicle until the message clears.

Seat Belt Reminders
Driver Seat Belt Reminder
Light
There is a driver seat belt reminder
light on the instrument cluster.
When the vehicle is started, this
light flashes and a chime may come
on to remind the driver to fasten
their seat belt. Then the light stays
on solid until the belt is buckled.
This cycle may continue several
times if the driver remains or
becomes unbuckled while the
vehicle is moving.

5. Thread the lower lock nut (2)back on to the center support
tube and torque it against the
spring seat (1) to 25 Y
(18.4 lb ft).
Load Limit
Limit vehicle load to the driver only,
with no other cargo. Inflate the front
tires to 159 kPa (23 psi) and the rear
tires to 165 kPa (24 psi). Drive at a
maximum speed of 296 km/h
(184 mph).
Road Course target hot pressures of
220–240 kPa (32–35 psi). Value will
vary based on driving style, track,
temperature, and weather
conditions.
Wheel Alignment
Caution
Using these wheel alignment
settings may cause excessive tire
wear. Only use these wheel
alignment settings for racing or (Continued)
Caution (Continued)
competitive driving. Excessive tire
wear is not covered under the
vehicle warranty.
The racing and competitive driving
wheel alignment settings should be
set as described here.
To achieve the track alignment
specified settings: 1. The upper control arm to body washers on all four corners will
need to be moved from
between the body and the
control arm and relocated
between the head of the bolt
and the control arm.
2. Adjust the lower control arm cam bolt position to achieve
the following specifications.
Front (per corner)
. Caster: +8.0 degrees

Caster: 0 degrees
. Camber: -2.5 degrees
. Toe (total): 0.1 degrees toe in
. Thrust Angle: 0 degrees
After track use, reinstall washers
between the body and the control
arms. Reset to factory alignment
settings.
General Information
If reduced performance is
experienced during track events or
competitive driving, turning off the
A/C will help to improve engine
performance.
Maintain a mixture of 40%
DEX-COOL coolant and 60% clean,
drinkable water to optimize engine
performance.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types

{Warning
An underhood electric fan can
start up even when the engine is
not running and can cause injury.
Keep hands, clothing, and tools
away from any underhood
electric fan.
{Warning
Do not touch heater or radiator
hoses, or other engine parts.
They can be very hot and can
burn you. Do not run the engine if
there is a leak; all coolant could
leak out. That could cause an
engine fire and can burn you. Fix
any leak before driving the
vehicle.
Engine Coolant
The cooling system in the vehicle is
filled with DEX-COOL engine
coolant. See Recommended Fluids
and Lubricants 0295. The fluid
requires changing at certain
intervals. See Maintenance
Schedule 0286.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see Engine Overheating 0230.
What to Use
{Warning
Plain water, or other liquids such
as alcohol, can boil before the
proper coolant mixture will. With
plain water or the wrong mixture,
the engine could get too hot but
there would not be an overheat
warning. The engine could catch
fire and you or others could be
burned.
Use a mixture of 40% DEX-COOL
coolant and 60% clean, drinkable
water. If using this mixture, nothing
else needs to be added. This
mixture:
. Gives freezing protection down
to−28 °C (−18 °F), outside
temperature.
. Gives boiling protection up to
129 °C (265 °F), engine
temperature.
. Protects against rust and
corrosion.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12470550) - 2020 - CRC - 4/23/20
228 Vehicle Care
.Will not damage aluminum parts.
. Helps keep the proper engine
temperature.
Caution
Do not use anything other than a
mix of DEX-COOL coolant that
meets GM Standard
GMW3420 and clean, drinkable
water. Anything else can cause
damage to the engine cooling
system and the vehicle, which
would not be covered by the
vehicle warranty.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or into sewers, streams,
or bodies of water. Have the coolant
changed by an authorized service
center, familiar with legal
requirements regarding used
coolant disposal. This will help
protect the environment and your
health. If ambient temperatures are
anticipated below
−28 °C (−18 °F),
make sure a proper mixture ratio of
50% DEX-COOL coolant and 50%
clean, drinkable water is used.Checking Coolant
Be sure the cooling system is cool
and that the vehicle is on a level
surface.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down. If coolant is visible
but the coolant level is not at or
above the cold fill line, add a
mixture of 40% DEX-COOL coolant
and 60% clean, drinkable water at
the coolant recovery tank, but be
sure the cooling system is cool
before this is done. See Engine
Overheating 0230.
The surge tank is in the engine
compartment. See Engine
Compartment Overview 0215.
When the engine is cold, the coolant
level should be at the COLD FILL
indicator in the coolant surge tank.
When the engine is hot, the level
could be higher than the COLD FILL
indicator. If the coolant is below the
COLD FILL indicator when the
engine is hot, there could be a leak
in the cooling system.
If the coolant is low, add the coolant
or take the vehicle to your dealer for
service.
