Checking Coolant
The coolant recovery
tank cap has this
symbol on it. The tank
is located in the
engine compartment
toward the front
of the engine on the
passenger’s side of the
vehicle.
SeeEngine Compartment Overview on page 298
for more information on location.
The vehicle must be on a level surface when
checking the coolant level.
When the engine is cold, the coolant level should
be at the COLD FILL line or a little higher. The
COLD FILL line is near the bottom of the tank and
sticks out from the rear of the tank.
Adding Coolant
If more coolant is needed, add the proper
DEX-COOL®coolant mixture at the coolant
recovery tank, but only when the engine is cool.
If the coolant recovery tank is completely empty, a
special ll procedure is necessary. SeeCooling
System on page 312for more information.
{CAUTION:
Turning the radiator pressure cap when
the engine and radiator are hot can allow
steam and scalding liquids to blow out
and burn you badly. With the coolant
recovery tank, you will almost never
have to add coolant at the radiator. Never
turn the radiator pressure cap — even a
little — when the engine and radiator
are hot.

Cooling System
When you decide it is safe to lift the hood, here is
what you will see:
A. Pressure Cap
B. Coolant Recovery Tank
C. Electric Engine Cooling Fan{CAUTION:
An electric engine cooling fan under the
hood can start up even when the engine
is not running and can injure you. Keep
hands, clothing, and tools away from any
underhood electric fan.
If the coolant inside the coolant recovery tank is
boiling, do not do anything else until it cools down.
The vehicle should be parked on a level surface.
When the engine is cold, the coolant level
should be at or above the COLD FILL line. If it is
not, you may have a leak at the pressure cap
or in the radiator hoses, heater hoses, radiator,
water pump, or somewhere in the cooling system.

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:
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.1. You can remove the
pressure cap when
the cooling system,
including the
pressure cap and
upper radiator hose,
is no longer hot.
Turn the pressure
cap slowly
counterclockwise.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left to
be vented.
2. Then keep turning the pressure cap and
remove it.
3. Add the proper DEX-COOL
®coolant mixture
to the coolant ll port, up to the base of the
port. SeeEngine Coolant on page 306
for more information about the proper coolant
mixture.
4. Rinse or wipe any spilled coolant from the
engine and the compartment.
