{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.

Fiberglass Springs
(Composite Springs)
Notice:
If you use acidic or corrosive cleaning products,
engine degreasers or aluminum cleaning agents on
fiberglass springs, you may damage the springs.
The repairs would not be covered by your warranty.
Use only approved cleaners when cleaning your
vehicle's fiberglass springs.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on the vehicle. This damage
can take two forms: blotchy, ring-shaped discolorations,
and small, irregular dark spots etched into the paint
surface.
Although no defect in the paint job causes this, we will
repair, at no charge to the owner, the surfaces of new
vehicles damaged by this fallout condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever occurs first.
Vehicle Identification
Vehicle Identification Number (VIN)
This legal identifier is in the front corner of the
instrument panel, on the driver side. It can be seen
through the windshield from outside. The VIN also
appears on the Vehicle Certification and Service
Parts labels and certificates of title and registration.
Engine Identification
The eighth character in the VIN is the engine code.
This code identifies the vehicle's engine, specifications,
and replacement parts. See “Engine Specifications”
under Capacities and Specifications
on page 6‑108for
the vehicle's engine code.

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.

the Restraint Systems on page 2‑60.
.Engine air cleaner filter inspection. See Engine Air
Cleaner/Filter on page 6‑27.
