Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning
light will come on when
the engine has
overheated.
If this happens you should pull over and seeEngine
Overheating on page 309for more information.
Notice:Driving with the engine coolant
temperature warning light on could cause your
vehicle to overheat. SeeEngine Overheating
on page 309. Your vehicle could be damaged,
and it might not be covered by your warranty.
Never drive with the engine coolant
temperature warning light on.
This light will come on and ash when the
temperature of the automatic transaxle uid is too
high. If this happens you should pull over, shift
into PARK (P) and let the engine idle until the light
goes out.
This light will also come on briey when starting your
vehicle. If it does not, have your vehicle serviced.
Low Coolant Warning Light
This light comes on
briey when you turn
your ignition on.
If this light comes on and stays on, the coolant
level in your vehicle is low. If the light is on along
with an overheat warning, you may have a
serious overheating problem.
Notice:Driving with the low coolant warning
light on could cause your vehicle to overheat.
See “Engine Overheating” underEngine
Coolant on page 306. Your vehicle could be
damaged and the damages might not be
covered by your warranty.
SeeEngine Coolant on page 306for information
on what to do. Your vehicle should be serviced as
soon as possible.

Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 296
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.

Checking Coolant
The surge tank is located on the driver’s side
of the engine compartment. SeeEngine
Compartment Overview on page 296for more
information on location.
{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 COLD FILL line. When your engine is warm,
the level should be at the COLD FILL line or a
little higher.
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. SeeEngine
Overheating on page 309for instructions on
“How to Add Coolant to the Coolant Surge Tank.”

Cooling System
When you decide it is safe to lift the hood, here is
what you will see:
A. Electric Engine Fan
B. Coolant Surge Tank with Pressure Cap{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 surge tank is
boiling, do not do anything else until it cools
down. The vehicle should be parked on a
level surface.
311
ProCarManuals.com

The coolant level should be at the COLD FILL
line. If it is not, you may have a leak at 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 re,
and you could be burned. Get any leak
xed before you drive the vehicle.If there seems to be no leak, with the engine on,
check to see if the electric engine cooling fan
is running. If the engine is overheating, the
fan should be running. If it is not, your vehicle
needs service. Turn off the engine.
Notice:Engine damage from running your
engine without coolant is not covered by
your warranty.
Notice:Using coolant other than DEX-COOL®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant could require changing sooner, at
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. 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
Notice:This vehicle has a specic coolant ll
procedure. Failure to follow this procedure
could cause your engine to overheat and
be severely damaged.
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 COLD
FILL line, 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. SeeEngine Coolant
on page 306for more information.
{CAUTION:
Steam and scalding liquids from a hot
cooling system can blow out and burn
you badly. They are under pressure, and if
you turn the coolant surge tank pressure
cap — even a little — they can come out at
high speed. Never turn the cap when the
cooling system, including the coolant
surge tank pressure cap, is hot. Wait for
the cooling system and coolant surge
tank pressure cap to cool if you ever have
to turn the pressure cap.

4. With the coolant surge tank pressure cap off,
start the engine and let it run until you can
feel the upper radiator hose getting hot.
Watch out for the engine cooling fan.By this time, the coolant level inside the
coolant surge tank may be lower. If the level
is lower, add more of the proper DEX-COOL
®
coolant mixture to the coolant surge tank
until the level reaches the COLD FILL line.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight.
Check the level in the surge tank when the cooling
system has cooled down. If the coolant is not at
the proper level, repeat Steps 1 through 3 and
reinstall the pressure cap. If the coolant still is not
at the proper level when the system cools down
again, see your retailer.
