Checking Intercooler System Coolant
(4.4L V8 STS-V Engine Only)
See Engine Compartment Overview on page 5-12 for
the location of the intercooler system pressure cap.
Notice: This vehicle has a specific coolant
fill procedure. Failure to follow this procedure
could cause your engine to overheat and be
severely damaged.
Park the vehicle on a level surface and turn off the
engine. When the engine is cold, the coolant level
should be at or above the FULL COLD line. The FULL
COLD line has an arrow pointing to it.
Adding Coolant
If you need more coolant, add the proper DEX-COOL
®
coolant mixture at the intercooler fill neck, but only
when the engine is cool. See Cooling System on
page 5-33 for instructions on how to add coolant to the
intercooler fill neck.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
When replacing a pressure cap, make sure it is
hand-tight and fully seated.
