2010 CHEVROLET CORVETTE oil temperature

COOLANT OVER TEMPERATURE
This message displays and a sound will be heard if the
engine coolant exceeds 124°C (255°F). If you have
been operating the vehicle under normal driving
conditions, pull off the road, stop the vehicle, and
turn off the engine as soon as possible.
You can monitor the coolant temperature with the
gauges button on the DIC or the engine coolant
temperature gauge on the instrument panel cluster.
See Engine Overheating
on page 6‑38,DIC Operation
and Displayson page 4‑47, and Engine Coolant
Temperature Gauge on page 4‑40.
To acknowledge the message, press the RESET button.
The message and sound will come back on until this
condition changes. If you do not press the RESET
button, the message remains on until the condition
changes.
CRUISE DISENGAGED
This message displays briefly when you disengage
the cruise control system by stepping on the brake on
an automatic transmission vehicle or the clutch on a
manual transmission vehicle, or by turning off the cruise
control switch. See Cruise Control
on page 4‑7for
more information.
ENGINE DRAG CONTROL ACTIVE
This message displays when engine drag control is
active. When driving in a lower gear in rainy, snowy,
or icy conditions and then letting up on the accelerator
or downshifting, the rear wheels may begin to slip and
this message displays. This message stays on for a few
seconds following the engine drag control event.
ENGINE OVERHEATED –STOP ENGINE
This message displays and a sound will be heard when
the engine has overheated. Stop and turn the engine
off immediately to avoid severe engine damage.
See Engine Overheating on page 6‑38.
ENGINE PROTECTION REDUCE
ENGINE RPM
This message displays if the engine oil temperature
exceeds 160°C (320°F). Check the engine coolant
temperature and engine oil level. If the engine is
too hot, see Engine Overheating
on page 6‑38.
The vehicle may need service, so see your dealer/
retailer.
You can monitor the oil temperature with the gauges
button on the DIC. See DIC Operation and Displays
on
page 4‑47.

Checking Engine Oil (ZO6, ZR1, and
Grand Sport)
A. Engine Oil Dipstick
B. Engine Oil Fill Cap
It is a good idea to check the engine oil level at each
fuel fill. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground. The engine oil dipstick handle is a yellow loop.
The dipstick is located on the dry sump engine oil tank.
See
Engine Compartment Overview
on page 6‑14for
the location of the dry sump engine oil tank.
These vehicles have a racetrack‐ready dry sump
engine lubrication system. This high‐performance
system operates differently than a standard engine
lubrication system and requires a special procedure
when checking the engine oil level. Follow this
procedure closely when checking the engine oil level.
The engine oil level must be checked when the
engine is warm. Cold oil level in the dry sump tank
may not indicate the actual amount of oil in the system.
With this system, engine oil is contained in an external
tank, separate from the engine. Under normal operating
conditions, the oil pan under the engine does not store
any oil. If the vehicle has been parked for an extended
period without the engine being started, some oil will
seep back into the oil pan, reducing the amount of oil
held in the dry sump tank and there could be no engine
oil at all showing on the dipstick. This is normal since
the dipstick is designed to read engine oil level only
after the engine has run long enough to reach normal
operating temperature. Do not add engine oil based on
6-21

Oils meeting these
requirements should have
the starburst symbol on
the container. This symbol
indicates that the oil has
been certified by the
American Petroleum
Institute (API).
This vehicle's engine was filled at the factory with a
Mobil 1
®synthetic oil meeting all requirements for this
vehicle.
Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard GM4718M
might not be available. You can add substitute oil
designated SAE 5W-30 with the starburst symbol at all
temperatures. Substitute oil not meeting GM Standard
GM4718M should not be used for an oil change.
Engine Oil Additives / Engine Oil
Flushes
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM Standard
GM4718M are all that is needed for good performance
and engine protection.
Engine oil system flushes are not recommended and
could cause engine damage not covered by the vehicle
warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer that indicates when to
change the engine oil and filter. This is based on
engine revolutions and engine temperature, and not
on mileage. Based on driving conditions, the mileage at
which an oil change is indicated can vary considerably.
For the oil life system to work properly, the system must
be reset every time the oil is changed.

What to Use
{WARNING:
Adding only plain water to the cooling system
can be dangerous. Plain water, or some other
liquid such as alcohol, can boil before the proper
coolant mixture will. The vehicle's coolant warning
system is set for the proper coolant mixture.
With plain water or the wrong mixture, the engine
could get too hot but would not get the overheat
warning. The engine could catch fire and you or
others could be burned. Use a 50/50 mixture of
clean, drinkable water and DEX-COOL
®coolant.
Use a 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant. If using this mixture, nothing else
needs to be added. This mixture:
.Gives freezing protection down to −37°C (−34°F),
outside temperature.
.Gives boiling protection up to 129°C (265°F),
engine temperature.
.Protects against rust and corrosion.
.Will not damage aluminum parts.
.Helps keep the proper engine temperature. Notice:
If an improper coolant mixture is used,
the engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
Notice: If extra inhibitors and/or additives are used
in the vehicle's cooling system, the vehicle could be
damaged. Use only the proper mixture of the engine
coolant listed in this manual for the cooling system.
See Recommended Fluids and Lubricants
on
page 7‑10for more information.
Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
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 FULL COLD mark, add a 50/50 mixture of
clean, drinkable water and DEX-COOL coolant at the
coolant recovery tank, but be sure the cooling system
is cool before this is done. See Engine Coolant
on
page 6‑34for more information.

Overheated Engine Protection
Operating Mode
This emergency operating mode lets the vehicle
be driven to a safe place, up to 50 miles (80 km),
in an emergency situation. If an overheated engine
condition exists and the messages COOLANT OVER
TEMPERATURE and REDUCED ENGINE POWER
are displayed, along with the check engine light, an
overheat protection mode which alternates firing groups
of cylinders helps prevent engine damage. In this
mode, there is a significant loss in power and engine
performance.
Driving extended distances in the overheat protection
mode should be avoided.
Notice: After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded.
Repair the cause of coolant loss, change the oil
and reset the oil life system. See Engine Oil
on
page 6‑19.
Power Steering Fluid
See Engine Compartment
Overviewon page 6‑14for reservoir location.
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.
