Checking Intercooler System Coolant
(2.0L L4 Engine Only)
Park your vehicle on a level surface and turn off
the engine. When your engine is cold, the coolant
level should be just visible within the horizontal
tube section of the fill neck. When your engine is
warm, the coolant level could be as high as
the FULL HOT line, or a little higher. The FULL
HOT line has an arrow pointing down at it.
Notice: This vehicle has a specific coolant fill
procedure. Failure to follow this procedure
could cause your engine to overheat and
be severely damaged.

Adding Coolant
If you need more coolant, add the proper
®
DEX-COOL coolant mixture at the surge tank
and/or intercooler fill neck, but only when the
engine is cool. See Cooling System on page 300
for instructions on how to add coolant to the
coolant surge tank and/or 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.
