Cooling System
(Intercooler)
The 6.2L LS9 supercharged
V8 engine has an intercooler
cooling system. See Engine
Compartment Overview on
page 10‑10 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 13‑15.
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
the dealer 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 5 years or
240 000 km (150,000 mi), 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 10‑34.
