Engine Oil
Checking Engine Oil
(Except ZO6, ZR1, and Grand Sport)
If the CHECK OIL LEVEL message displays on the
Driver Information Center (DIC), check the engine oil
level right away. For more information, see Driver
Information Center (DIC)
on page 4‑47. Check the
engine oil level regularly; this is an added reminder.
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.
See Engine Compartment Overview
on page 6‑14for the location of the engine oil dipstick.
1. Turn off the engine and give the oil a few minutes to drain back into the oil pan. If this is not done,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a lint‐free paper towel or a cloth, then push it back in all
the way.
3. Remove the dipstick again, keeping the tip down and read the level on the cross‐hatched area.
Oil levels that fall in the cross‐hatched area are
normal.
4. Push the dipstick back in all the way.

When to Check and What to Use
The hydraulic clutch fluid
reservoir cap has this
symbol on it. See Engine
Compartment Overview
on page 6‑14for
reservoir location.
Refer to the Maintenance Schedule for the proper
fluid to use. See Recommended Fluids and Lubricants
on page 7‑10. The fluid requires changing every
two years. See Scheduled Maintenance on page 7‑3.
How to Check and Add Fluid
Visually check the clutch fluid reservoir to make sure
the fluid level is at the MIN (minimum) line on the side
of the reservoir. The hydraulic clutch fluid system
should be closed and sealed.
Do not remove the cap to check the fluid level or to
top‐off the fluid level. Remove the cap only when
necessary to add the proper fluid until the level
reaches the MIN line.
Cooling System (Engine)
The cooling system allows the engine to maintain the
correct working temperature.

{WARNING:
An electric engine cooling fan under the hood 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.
{WARNING:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them.
If you do, you can be burned.
Do not run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle. Notice:
Using coolant other than DEX-COOL
®can
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant could
require changing sooner, at 50 000 km (30,000 miles)
or 24 months, whichever occurs first. Any repairs
would not be covered by the vehicle warranty.
Always use DEX-COOL
®(silicate-free) coolant
in the vehicle.
Cooling System (Intercooler)
The 6.2L LS9 supercharged V8 engine has an
intercooler cooling system. See Engine Compartment
Overview
on page 6‑14for location of the intercooler.
The intercooler cooling system has a special procedure
for draining and adding coolant. Because this procedure
is difficult, see your dealer/retailer for service if the
intercooler is low on coolant. The procedure can also
be found in the service manual. To purchase a service
manual, see Service Publications Ordering Information
on page 8‑16.
6-33

Checking Coolant
1. Verify that the engine and intercooler are no longer hot.
2. Place a cloth to absorb possible coolant loss under the driver's side bleeder valve (A). 3. Loosen, but do not completely unscrew the bleeder
valve to check for coolant in the system.
4. Tighten the bleeder valve if there is coolant flowing out of the bleeder valve.
5. If there is no coolant flowing out of the bleeder valve, there could be a leak in the system. Tighten
the bleeder valve and contact your dealer/retailer
for service.
Engine Coolant
The cooling system in the vehicle is filled with
DEX-COOL®engine coolant. This coolant is designed
to remain in the vehicle for five years or 240 000 km
(150,000 miles), whichever occurs first.
The following explains the cooling system and how
to check and add coolant when it is low. If there is
a problem with engine overheating, see Engine
Overheating on page 6‑38.
6-34

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.
6-35

The engine coolant surge
tank is located toward
the rear of the engine
compartment on the
driver side of the vehicle.
See Engine Compartment
Overview
on page 6‑14for more information on
location.
When the engine is cold, the coolant level should be at
the FULL COLD mark on the coolant surge tank.
When the engine is hot, the level could be higher
than the FULL COLD line. If the coolant is below the
FULL COLD line 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 a dealer/retailer for service.
How to Add Coolant to the Coolant
Surge Tank
{WARNING:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot enough.
Do not spill coolant on a hot engine.
{WARNING:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They are
under pressure, and if you turn the coolant surge
tank pressure cap —even a little —they can come
out at high speed. Never turn the cap when the
cooling system, including the coolant surge tank
pressure cap, is hot. Wait for the cooling system
and coolant surge tank pressure cap to cool if you
ever have to turn the pressure cap.
