Front License Plate/Bracket Removal
(ZL1 Only)
For track use, the front license plate and
bracket can be removed from the fascia for
increased airflow. Remove the license plate
to access the four screws that attach the
license plate bracket to the front fascia.
Water Deflector
If operating a ZL1 on a closed course in hot
temperatures, remove the water deflector to
increase airflow and improve cooling.
Remove the three bolts. Replace
immediately after track use to protect the
engine compartment from water intrusion.
Torque to 4.5Y(40 lb in).
Wicker Bill
A rear spoiler wicker bill is available for
LS/LT and SS with the 1LE package only.
If equipped with a wicker bill, use the
instructions for installation.
Underbody Air Deflector Tire Dam Kit
The underbody air deflector tire dam kit
provided with ZL1 vehicles reduces the
amount of aerodynamic lift on the front
axle for better handling. The original tire
dams must be reinstalled after the track
event. For installation, see the instructions
provided with the kit.

16 Driving and Operating
Supplemental Power Steering Deflectors
The supplementary power steering
deflectors, if equipped, provide additional
cooling to the power steering gear during
track events. Remove the noise shields and
install the deflectors as directed by the
enclosed instruction sheet. Remove the
deflectors and reinstall the noise shields
immediately after track use to protect the
engine compartment from additional water
intrusion.
Adjustable Front Struts (ZL1 1LE Only)
Camber Position for Track Events
The front strut top mount can be positioned
two ways. The original setting is in the
street position, but it can be turned 180° to
the track position for additional negative
camber on the front.To adjust the position:
1. Raise the vehicle so the tires are slightly off the ground.
2. From the bottom side of the strut topmount, remove the Allen bolt that
secures the top mount alignment pin to
the top mount.
3. Remove the three strut mount bolts andthe alignment pin.

Engine Oil
To ensure proper engine performance and
long life, careful attention must be paid to
engine oil. Following these simple, but
important steps will help protect your
investment:
.Use engine oil approved to the proper
specification and of the proper viscosity
grade. See “Selecting the Right Engine
Oil” in this section.
.Check the engine oil level regularly and
maintain the proper oil level. See
“Checking Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the appropriate
time. See“Engine Oil Life System” in the
owner’s manual.
.Always dispose of engine oil properly. See
“What to Do with Used Oil” in this
section.
Checking Engine Oil
Check the engine oil level regularly, every
650 km (400 mi), especially prior to a long
trip. The engine oil dipstick handle is a loop.
See Engine Compartment Overview 027 for
the location.
{Warning
The engine oil dipstick handle may be
hot; it could burn you. Use a towel or
glove to touch the dipstick handle.
If a low oil Driver Information Center (DIC)
message displays, check the oil level.
Follow these guidelines:
.To get an accurate reading, park the
vehicle on level ground. Check the engine
oil level after the engine has been off for
at least two hours. Checking the engine
oil level on steep grades or too soon after
engine shutoff can result in incorrect readings. Accuracy improves when
checking a cold engine prior to starting.
Remove the dipstick and check the level.
.If unable to wait two hours, the engine
must be off for at least 15 minutes if the
engine is warm, or at least 30 minutes if
the engine is not warm. Pull out the
dipstick, wipe it with a clean paper towel
or cloth, then push it back in all the way.
Remove it again, keeping the tip down,
and check the level.
When to Add Engine Oil
If the oil is below the cross-hatched area at
the tip of the dipstick and the engine has
been off for at least 15 minutes, add 1 L (1
qt) of the recommended oil and then
recheck the level. See
“Selecting the Right
Engine Oil” later in this section for an
explanation of what kind of oil to use. For
engine oil crankcase capacity, see Capacities
and Specifications 043.

Vehicle Care 31
1. Remove the five screws and lift the coverassembly. Use caution not to drop any
of the loose screws.
{Warning
If part replacement is necessary, the part
must be replaced with one of the same
part number or with an equivalent part.
Use of a replacement part without the
same fit, form, and function may result
in personal injury or damage to the
vehicle.
2. Inspect or replace the air cleaner/filter.
3. Reverse Steps 1 and 2 to reinstall the housing cover. 4. If equipped, reset the engine air filter life
system after replacing the engine air
filter. See Engine Air Filter Life System
0 30.
{Warning
Operating the engine with the air
cleaner/filter off can cause you or others
to be burned. Use caution when working
on the engine. Do not start the engine or
drive the vehicle with the air cleaner/
filter off, as flames may be present if the
engine backfires.
Caution
If the air cleaner/filter is off, dirt can
easily get into the engine, which could
damage it. Always have the air cleaner/
filter in place when driving.
Cooling System
The cooling system allows the engine to
maintain the correct working temperature.
1. Engine Coolant Surge Tank and
Pressure Cap
2. Engine Cooling Fan (Out of View)
{Warning
An underhood electric fan can start up
even when the engine is not running and
can cause injury. Keep hands, clothing,
and tools away from any underhood
electric fan.

32 Vehicle Care
{Warning
Do not touch heater or radiator hoses,
or other engine parts. They can be very
hot and can burn you. Do not run the
engine if there is a leak; all coolant could
leak out. That could cause an engine fire
and can burn you. Fix any leak before
driving the vehicle.
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.
Engine Coolant
See”Engine Coolant” under“Cooling
System” in the owner’s manual.
Engine Overheating
See“Engine Overheating” in the owner’s
manual.
Brakes
Due to California and Washington law, brake
service for some high-performance Camaros
manufactured after December 31, 2020,
cannot be conducted using GM original
equipment brake pads in those states.
Service requiring original equipment brake
pads can be performed at any GM
dealership in the remaining 48 states.
Otherwise, replacement of brake pads in
California or Washington will require
replacement of additional brake system
components. See your dealer to verify the
manufacture date for your vehicle.
Wheels and Tires
Low-Profile Tires
If the vehicle has 285/30ZR20,
305/30ZR20, 305/30ZR19, or 325/30ZR19
size tires, they are classified as
low-profile tires. Caution
Low-profile tires are more susceptible to
damage from road hazards or curb impact
than standard profile tires. Tire and/or
wheel assembly damage can occur when
coming into contact with road hazards
like potholes, or sharp edged objects,
or when sliding into a curb. The warranty
does not cover this type of damage. Keep
tires set to the correct inflation pressure
and when possible, avoid contact with
curbs, potholes, and other road hazards.
Competition Oriented Tires
This vehicle may come with 305/30ZR19 and
325/30ZR19 Goodyear Eagle F1 Supercar 3R
competition oriented tires that are DOT
approved for street use. Competition
oriented tires use a special tread pattern
and compound that provide more grip than
normal road tires. The minimum tread depth
will be reached earlier than typical tires,
resulting in reduced tire life. This special
tread pattern and compound will have
decreased performance in cold climates,
heavy rain, and standing water. It is
recommended that winter tires be installed
