2020 CHEVROLET CORVETTE oil change

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12470550) - 2020 - CRC - 4/23/20
222 Vehicle Care
This vehicle has 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
changing the engine oil and filter.
SeeEngine Oil 0218.
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on.
Change the oil as soon as possible
within the next 1 000 km (600 mi).
It is possible that, if driving under
the best conditions, the oil life
system may not indicate that an oil
change is necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level. If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Scroll through the DIC Info Pages menu until the
REMAINING OIL LIFE
percentage is displayed. See
Driver Information Center (DIC)
0108.
2. Press and hold SEL on the DIC while the Oil Life display is
active. The oil life will change
to 100%.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.
Dual Clutch Transmission
Fluid
How to Check Dual Clutch
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer and have it repaired as soon
as possible.
The vehicle is not equipped with a
transmission fluid level dipstick.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at the dealer. Contact the
dealer for additional information or
the procedure can be found in the
service manual. To purchase a
service manual, see Publication
Ordering Information 0311.

Dual Clutch Transmission
Fluid Life System
When to Change the Dual
Clutch Transmission Fluid
This vehicle has a computer that
indicates when to change the
transmission fluid. This is based on
a combination of factors which
include temperature and miles
driven. Based on driving conditions, the mileage at which a fluid change
is indicated can vary considerably.
For the fluid life system to work
properly, the system must be reset
every time the fluid is changed.
When the system has calculated
that fluid life has been diminished, it
indicates that a fluid change is
necessary. A CHANGE
TRANSMISSION FLUID SOON
message comes on. Change the
fluid as soon as possible within the
next 1 000 km (600 mi). Failure to
change transmission fluid at
required intervals could lead to
suboptimal transmission
performance. Your dealer has
trained service technicians who will
change the fluid and reset the
system. If the system is ever reset
accidentally, the fluid must be
changed at 72 000 km (45,000 mi)
since the last fluid change.
How to Reset the Dual Clutch

.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.

to a clean area frequently to
prevent forcing the soil in to the
fabric.
4. Continue gently rubbing the soiled area until there is no
longer any color transfer from
the soil to the cleaning cloth.
5. If the soil is not completely removed, use a mild soap
solution followed only by plain
water.
If the soil is not completely
removed, it may be necessary to
use a commercial upholstery
cleaner or spot lifter. Test a small
hidden area for colorfastness before
using a commercial upholstery
cleaner or spot lifter. If ring
formation occurs, clean the entire
fabric or carpet.
After cleaning, use a paper towel to
blot excess moisture.Cleaning High Gloss Surfaces
and Vehicle Information and
Radio Displays
Use a microfiber cloth on high gloss
surfaces or vehicle displays. First,
use a soft bristle brush to remove
dirt that can scratch the surface.
Then gently clean by rubbing with a
microfiber cloth. Never use window
cleaners or solvents. Periodically
hand wash the microfiber cloth
separately, using mild soap. Do not
use bleach or fabric softener. Rinse
thoroughly and air dry before
next use.
Caution
Do not attach a device with a
suction cup to the display. This
may cause damage and would
not be covered by the vehicle
warranty.
Instrument Panel, Leather,
Vinyl, Other Plastic Surfaces,
Low Gloss Paint Surfaces, and
Natural Open Pore Wood
Surfaces
Use a soft microfiber cloth
dampened with water to remove
dust and loose dirt. For a more
thorough cleaning, use a soft
microfiber cloth dampened with a
mild soap solution.
Caution
Soaking or saturating leather,
especially perforated leather, as
well as other interior surfaces,
may cause permanent damage.
Wipe excess moisture from these
surfaces after cleaning and allow
them to dry naturally. Never use
heat, steam, or spot removers. Do
not use cleaners that contain
silicone or wax-based products.
Cleaners containing these
solvents can permanently change (Continued)
