INTERCOOLER SYSTEM (CTS-V
MODEL ONLY)
NOTICE
The intercooler system on the
6.2L V8 engine has a specific
coolant fill procedure. Failure to
follow this procedure may
result in the engine overheating
and in severe engine damage.
See "Intercooler System" under
"Engine Overheating" in
Section 5 for the proper fill
procedure.
1. The vehicle must be on a level
surface.
2. Turn off the engine.
3. Locate the intercooler system
pressure cap.
If the engine is cold, the coolant
level should be near the
COLD
FILL
line on the side of the coolant
fill bottle. If it is not, you could
have a leak in the
cooling system.
CAUTION
Steam and scalding liquids from
a hot cooling system can blow
out and burn you badly. Never
turn the cap when the engine
and cooling system are hot.
If the coolant level is low, add a
50/50 mixture of water and
DEX-COOL
®
coolant to bring the
level to the proper mark.
CAUTION
Adding only plain water or
a liquid other than the
recommended coolant can be
dangerous. The engine could
overheat, but you would not
get the overheat warning. The
engine could catch on fire and
you or others could be burned.
