How to Add Coolant to the
Intercooler System Fill Neck
(2.0L L4 Supercharged Engine Only)
If you have not found a problem yet, turn the engine off
and allow it to cool down, then check to see if coolant
is visible within the horizontal tube section of the
fill neck. If coolant is not visible, add a 50/50 mixture of
clean, drinkable water and DEX-COOL
the fill neck. Be sure the Intercooler System, including
the Intercooler System pressure cap, is cool before
doing so. See Engine Coolant on page 5-25 for more
information.
CAUTION:
{
Turning the Intercooler System pressure cap
when the engine and intercooler are hot can
allow steam and scalding liquids to blow out
and burn you badly. Never turn the Intercooler
System pressure cap, even a little, when the
engine and intercooler are hot.

Notice: In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
CAUTION:
{
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid such as alcohol, can boil before the
proper coolant mixture will. Your vehicle's
coolant warning system is set for the proper
coolant mixture. With plain water or the wrong
mixture, your engine could get too hot but you
would not get the overheat warning. Your
engine could catch fire and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
