Service
All vehicles have a label underhood that
identifies the refrigerant used in the vehicle.
The refrigerant system should only be
serviced by trained and certified technicians.
The air conditioning evaporator should never
be repaired or replaced by one from a
salvage vehicle. It should only be replaced
by a new evaporator to ensure proper and
safe operation.
During service, all refrigerants should be
reclaimed with proper equipment. Venting
refrigerants directly to the atmosphere is
harmful to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite, or other
health-based concerns.
The air conditioning system requires periodic
maintenance. See Maintenance Schedule
0 293.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14622938) - 2021 - CRC - 9/22/20
180 Driving and Operating
Be sure to follow all service procedures
before driving the vehicle at track events or
competitively.
{Warning
Prior to each track event and again
before returning to public roads, tighten
the wheel nuts with a torque wrench to
the proper torque specification. Wheel
nuts that are improperly or incorrectly
tightened can cause the wheels to
become loose or come off, resulting in a
crash. SeeCapacities and Specifications
0 305 for wheel nut torque specifications.
If equipped, the front license plate bracket
should be removed and replaced with the
aero cover for track use.
Engine Sound Management Setting Caution
Do not place the vehicle in Engine Sound
Management–Stealth mode. Damage
could result to exhaust valve actuators.
Engine Oil
Caution
If the vehicle is used for track events and
competitive driving, the engine may use
more oil than it would with normal use.
Low oil levels can damage the engine.
Check the oil level often and maintain
the proper level. See Engine Oil0238.
Check the oil level often during track events
and competitive driving. See “Checking the
Engine Oil" in Engine Oil0238.
Engine Cooling
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.
Fuel
Unleaded gasoline, rated at 93 octane or
higher, is required.
Caution
Some high octane fuels contain additives
and compounds that may damage the
vehicle and void the vehicle warranty. See
Prohibited Fuels 0226.
Dual Clutch Transmission Fluid
The transmission fluid and external filter
should be changed after every 24 hours of
track usage. If prompted by the transmission
fluid life monitor that remaining fluid life is
low, the fluid and external filter should be
changed as soon as possible.
Add an additional 2 L (2 qt) of DCT
transmission fluid prior to track usage. It is
not required to remove the additional 2 L
(2 qt) of DCT fluid.
Any transmission level set or change should
be performed at your dealer.
Brakes
Battery Disconnect
Disconnect the battery before servicing the
hydraulic brake system. It is critical to
disconnect the battery before bleeding the
system, replacing the pads, or any other
work. The battery must be disconnected to

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14622938) - 2021 - CRC - 9/22/20
Driving and Operating 181
prevent the brake master cylinder from
pressurizing the hydraulic system during its
automated self diagnostic tests that can
possibly occur when a door is opened or the
remote key is present.
{Caution
To avoid personal injury and/or vehicle
damage, always disconnect the battery
before performing service work on the
hydraulic brake system. Bleeding the
brake system with the battery connected
can lead to excessive pressurization of
the system during automatic diagnostic
tests or diagnosis of a leak or air in the
braking system. A Diagnostic Trouble
Code (DTC) may set and vehicle speed
may be limited.
Brake Fluid
Replace existing brake fluid with a qualified
high performance DOT 4 brake fluid from a
sealed container. Brake fluid with a dry
boiling point >310 °C (590 °F) is qualified.
If high performance brake fluid is used,
replace it with GM approved brake fluid
before driving on public roads. If high
performance brake fluid is in the vehicle and
the age of the brake fluid is over a month old or unknown, replace the brake fluid
before track events and competitive driving.
Do not use silicone or DOT-5 brake fluids.
Check the fluid level before each competitive
driving event.
Brake System Flushing & Bleeding
The J55 brake system requires specific
processes for bleeding and fluid flushing.
These can be found in the service manual.
Properly bleeding the brake system is
required for proper operation of the
hydraulic brake system.
Brake Leak Detection
The hydraulic braking system has advanced
diagnostic capability to help detect hydraulic
leaks, trapped air, and other performance
issues. These diagnostics are active when
the hydraulic system is powered. In order to
avoid inadvertently setting a leak Diagnostic
Trouble Code (DTC), disconnect the battery
before servicing the brake system.
If the vehicle sets a DTC related to a brake
system leak, the Brake System Warning
Light will come on and vehicle speed may
be limited to 100 kph (62 mph). Any time a
leak DTC is set, the vehicle should be
inspected carefully for evidence of a leak
and should be repaired immediately. See
your dealer.
Brake Fade Warning Assist
The Brake Fade Warning Assist system
monitors the performance of the brake
system. If the system detects brake fade,
or if the brake fluid is near the boiling point,
the driver will be alerted.
The Brake Fade Warning Assist system is
designed for use with the factory-installed
brake pads or GM-approved replacement
pads. If the brake pads on the vehicle need
to be replaced, use GM-approved brake pads.
If this is not done, the brake fade warning
system may not function properly.
Stage 1 :
The Driver Information Center (DIC)
displays a “Reduce Braking to Avoid
Overheating” message and brake pedal
effort and travel is increased. When the
message displays, the driver should decrease
brake pedal pressure.
Stage 2 : The Driver Information Center
(DIC) displays a “Brakes Overheated Service
Now” message that the brake fluid
temperature is excessive and is about to
boil. The system increases brake pedal effort
and travel, and will also limit vehicle speed.
