2010 CHEVROLET CORVETTE engine coolant

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.

Adding Washer Fluid
Open the cap with the
washer symbol on it.
Add washer fluid until the
tank is full. See Engine
Compartment Overview
on page 6‑14for
reservoir location.
Notice:
.When using concentrated washer fluid,
follow the manufacturer's instructions for
adding water.
.Do not mix water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage the washer fluid tank and other
parts of the washer system. Also, water does
not clean as well as washer fluid.
.Fill the washer fluid tank only three-quarters
full when it is very cold. This allows for fluid
expansion if freezing occurs, which could
damage the tank if it is completely full.
.Do not use engine coolant (antifreeze) in
the windshield washer. It can damage the
vehicle's windshield washer system and
paint.
Brakes
Brake Fluid
The brake master cylinder
reservoir is filled with
DOT 3 brake fluid. See
Engine Compartment
Overview
on page 6‑14for the location of the
reservoir.
There are only two reasons why the brake fluid level in
the reservoir might go down:
.The brake fluid level goes down because of
normal brake lining wear. When new linings are
installed, the fluid level goes back up.
.A fluid leak in the brake hydraulic system can also
cause a low fluid level. Have the brake hydraulic
system fixed, since a leak means that sooner or
later the brakes will not work well.

Scheduled Maintenance
When the Change Engine Oil Message
Displays
Change engine oil and filter. See Engine Oilon
page 6‑19. An Emission Control Service.
When the Change Engine Oil message displays,
service is required for the vehicle as soon as possible,
within the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than a
year. The engine oil and filter must be changed at least
once a year and the oil life system must be reset. Your
dealer/retailer has trained service technicians who will
perform this work and reset the system. If the engine
oil life system is reset accidentally, service the vehicle
within 5 000 km/3,000 miles since the last service.
Reset the oil life system whenever the oil is changed.
See Engine Oil Life System on page 6‑25. When the Change Engine Oil message displays,
certain services, checks, and inspections are
required. The services described for Maintenance
I
should be performed at every engine oil change.
The services described for Maintenance IIshould
be performed when:.Maintenance Iwas performed the last time the
engine oil was changed.
.It has been 10 months or more since the Change
Engine Oil message has displayed or since the last
service.
Maintenance I
.Change engine oil and filter. See Engine Oilon
page 6‑19. An Emission Control Service.
.Engine coolant level check. See Engine Coolanton page 6‑34.
.Windshield washer fluid level check. See
Windshield Washer Fluid on page 6‑42.
.Tire inflation check. See Inflation - Tire Pressureon page 6‑70.
7-3

.Tire wear inspection. SeeTire Inspection and
Rotation on page 6‑76.
.Fluids visual leak check (or every 12 months,
whichever occurs first). A leak in any system must
be repaired and the fluid level checked.
.Engine air cleaner filter inspection (vehicles
driven in dusty conditions only). See Engine Air
Cleaner/Filter on page 6‑27.
.Brake system inspection (or every 12 months,
whichever occurs first).
Maintenance II
.Perform all services described in Maintenance I.
.Steering and suspension inspection. Visual
inspection for damaged, loose, or missing parts
or signs of wear.
.Engine cooling system inspection. Visual
inspection of hoses, pipes, fittings, and clamps
and replacement, if needed.
.Windshield wiper blade inspection for wear,
cracking, or contamination and windshield and
wiper blade cleaning, if contaminated. See
Windshield and Wiper Blades
on page 6‑96.
Worn or damaged wiper blade replacement.
See Windshield Wiper Blade Replacement
on
page 6‑59.
.Body hinges and latches, key lock cylinders, any
folding seat hardware, and rear compartment,
hood, and console door hinges and latches
lubrication. See Recommended Fluids and
Lubricants
on page 7‑10. More frequent
lubrication may be required when vehicle is
exposed to a corrosive environment. Applying
silicone grease on weatherstrips with a clean cloth
makes them last longer, seal better, and not stick
or squeak.
.Restraint system component check. See Checking
the Restraint Systems on page 2‑60.
.Engine air cleaner filter inspection. See Engine Air
Cleaner/Filter on page 6‑27.
.Passenger compartment air filter replacement
(or every 12 months, whichever occurs first). More
frequent replacement may be required if vehicle is
driven regularly under dusty conditions.
Additional Required Services

.Engine oil level check. See Engine Oilon
page 6‑19.
.Engine coolant level check. See Engine Coolanton page 6‑34.

Recommended Fluids and
Lubricants
Fluids and lubricants identified below by name, part
number, or specification can be obtained from your
dealer/retailer. Usage Fluid/Lubricant
Engine Oil The engine requires a special engine
oil meeting GM Standard GM4718M.
Oils meeting this standard can be
identified as synthetic, and should
also be identified with the American
Petroleum Institute (API) Certified for
Gasoline Engines starburst symbol.
However, not all synthetic API oils
with the starburst symbol will meet
this GM standard. Look for and use
only an oil that meets GM Standard
GM4718M. For the proper viscosity,
see
Engine Oil on page 6‑19.
