{ CAUTION:
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.
{ CAUTION:
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 5-14 for 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 7-16.
