NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn't be covered by your
warranty. Too much water in the mixture can
freeze and crack the engine, radiator, heater core
and other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don't have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
Checking Coolant
The surge tank is located next to the engine block on the
passenger's side of the engine.
The cooling system is under a lot of pressure when it is
hot. If the CHECK COOLANT LEVEL message
appears on the Driver Information Center (DIC), you
will need to add coolant.

CAUTION:
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
Never turn the surge tank pressure cap
-- even a
little
-- when the engine and radiator are hot.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the full
cold mark, which is 2.5 inches (6.4 cm) below the base
of the fill neck. Use a flashlight as necessary to see into
the tank.
If the CHECK COOLANT LEVEL message comes on
and stays on, it means you're low on engine coolant.For more information, see ªCheck Coolant Level
Messageº in the Index.
Adding Coolant
If you need more coolant, add the proper DEX
-COOL

coolant mixture at the surge tank, but only when the
engine is cool.
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. Don't spill coolant on a hot engine.
When replacing the pressure cap, make sure it
is hand
-tight.
