A low coolant level should be indicated by a LOW

ENGINE COOLANT message on the Driver Information

Center (DIC). If it is, you may have a leak at the pressure

cap or in the radiator hoses, heater hoses, radiator, water

pump or somewhere else in the cooling system.

{CAUTION:

Heater and radiator hoses, and other engine

parts, can be very hot. Do not touch them.

If you do, you can be burned.

Do not run the engine if there is a leak. If you run

the engine, it could lose all coolant. That could

cause an engine ﬁre, and you could be burned.

Get any leak ﬁxed before you drive the vehicle.

If there seems to be no leak, with the engine on, check

to see if the electric engine cooling fans are running.

If the engine is overheating, both fans should be

running. If they are not, your vehicle needs service.

Notice: Engine damage from running your engine

without coolant is not covered by your warranty.

See Overheated Engine Protection Operating Mode

(4.6L V8 Engine) on page 5-40 for information on

driving to a safe place in an emergency.

Notice: Using coolant other than DEX-COOL

may

cause premature engine, heater core or radiator

corrosion. In addition, the engine coolant may

require changing sooner, at 30,000 miles (50 000 km)

or 24 months, whichever occurs ﬁrst. Any repairs

would not be covered by your warranty. Always use

DEX-COOL

(silicate-free) coolant in your vehicle.

How to Add Coolant to the Coolant

Surge Tank

If you have not found a problem yet, check to see if

coolant is visible in the surge tank. If coolant is

visible but the coolant level is not at the proper level

(4.5 inches (11.4 cm) below the top of the ﬁller neck),

add a 50/50 mixture of clean, drinkable water and

DEX-COOL

coolant at the coolant surge tank, but be

sure the cooling system, including the coolant surge tank

pressure cap, is cool before you do it. See Engine

Coolant (3.8L V6 Engine) on page 5-31 or Engine

Coolant (4.6L V8 Engine) on page 5-34 for more

information.
