{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 mi)
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 10‑8 for location of the
intercooler.
The intercooler cooling system has
a special procedure for draining and
adding coolant. Because this
procedure is difficult, see the dealer
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 13‑16.
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.

If coolant is needed, add the proper
DEX-COOL coolant mixture directly
to the surge tank, but be sure the
cooling system is cool before this
is done.
1. When the cooling system,including the coolant surge tank
pressure cap and upper radiator
hose, is no longer hot, remove
the pressure cap. Turn the pressure cap slowly
counterclockwise about
one-quarter turn and then stop.
If a hiss is heard, wait for that to
stop. A hiss means there is still
some pressure left.
2. Keep turning the pressure cap slowly, and remove it.
3. Fill the coolant surge tank withthe proper DEX-COOL coolant
mixture until the level inside
stabilizes at the FULL COLD
mark on the front of the
surge tank.
4. With the coolant surge tankpressure cap off, start the
engine and let it run until the
upper radiator hose can be felt
getting hot. Any time during this
procedure, watch out for the
engine cooling fan.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge tank
until the level stabilizes at the
FULL COLD mark on the coolant
surge tank.
