Engine Overheating - Chevrolet Corvette Owner's Manual

Engine Overheating

The vehicle has several indicators
to warn of engine overheating.
There is an engine coolant
temperature gauge on the
instrument cluster. See Engine
Coolant Temperature Gauge 0 109.
The vehicle may also display a
message on the Driver Information
Centre (DIC).
If the decision is made not to lift the
bonnet but to get service help
right away.
If the decision is made to lift the
bonnet, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fan is running. If the engine
is overheating, the fan should be
running. If it is not, do not continue
to run the engine, and have the
vehicle serviced.
Caution
Do not run the engine if there is a
leak in the engine cooling system.
This can cause a loss of all
coolant and can damage the
system and vehicle. Have any
leaks fixed right away.
If Steam Is Coming from the
Engine
Warning
Steam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure
cap, even a little, can cause them
to jet out at high speed and you
could be burned. Never turn the
cap when the cooling system,
including the pressure cap itself,
is hot. Wait for the cooling system
and pressure cap to cool.
Vehicle Care
If No Steam Is Coming from
the Engine
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
Climbs a long hill on a hot day.
Stops after high-speed driving.
Idles for long periods in traffic.
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the
highest temperature and to the
highest fan speed. Open the
windows as necessary.
3. When it is safe to do so, pull off
the road, shift to P (Park) or
N (Neutral) and let the
engine idle.
If the temperature overheat gauge is
no longer in the shaded area or an
overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slowly
