What to Use
Use a mixture of one-halfclean, drinkable waterand
one-half DEX-COOL®coolant which won’t damage
aluminum parts. If you use this coolant mixture,
you don’t need to add anything else.
{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 re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.Notice:If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost would not 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 do not
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.
Checking Coolant
The coolant recovery tank
is located between the
power steering uid
reservoir and the
underhood fuse block in
the engine compartment
on the passenger’s side of
the vehicle. SeeEngine
Compartment Overview on
page 5-12for more
information on location.

How to Add Coolant to the Radiator
Notice:Your engine has a specic radiator ll
procedure. Failure to follow this procedure could
cause your engine to overheat and be severely
damaged.
The radiator pressure cap is located in the front of the
engine compartment near the diagonal cross brace
on the passenger’s side of the vehicle. SeeEngine
Compartment Overview on page 5-12.1. Turn the pressure cap slowly counterclockwise until
it rst stops. (Don’t press down while turning the
pressure cap.)
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.
2. Then keep turning the pressure cap, but now push
down as you turn it. Remove the pressure cap.
5-40

{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.
3. If you have the 3800 V6 engine, remove the
3800 Series II V6 engine cover shield to access
the bleed valve.
3.1. Clean the area around the engine oil ll tube
and cap before removing. Twist the oil ll
tube, with cap attached, counterclockwise
and remove it.
3.2. Lift the engine cover shield at the front, slide
the catch tab out of the engine bracket and
remove the cover shield.
3.3. Put the oil ll tube, with cap attached, in the
valve cover oil ll hole until you’re ready to
replace the cover shield.
5-41

5. Fill the radiator with the proper DEX-COOL®
coolant mixture, up to the base of the ller neck.
SeeEngine Coolant on page 5-29
If you see a stream of coolant coming from an
air bleed valve, close the valve. Otherwise,
close the valves after the radiator is lled.
6. Rinse or wipe any spilled coolant from the engine
and the compartment.7. If you have the 3800 V6 engine, replace the
3800 Series II V6 engine cover shield.
7.1. Remove the oil ll tube, with cap attached,
from the valve cover.
7.2. Insert the catch tab on the cover shield
under the bracket on the engine.
7.3. Place the hole in the cover shield over the
hole in the valve cover. Install oil ll tube and
cap by twisting clockwise.
8. Then ll the coolant recovery tank to the COLD mark.
9. Put the cap back on the coolant recovery tank,
but leave the radiator pressure cap off.

Notice:If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other. If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set the
parking brake rmly on both vehicles involved in the
jump start procedure. Put an automatic transaxle in
PARK (P) or a manual transaxle in NEUTRAL before
setting the parking brake.Notice:If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the accessory power outlets. Turn off
the radio and all lamps that aren’t needed. This will
avoid sparks and help save both batteries. And it
could save your radio!
4. Open the hoods and locate the batteries. Find the
positive (+) and negative (−) terminal locations on
each vehicle.
You will not need to access your battery for jump
starting. Your vehicle has a remote positive (+) jump
starting terminal for that purpose. The remote
positive (+) terminal is located in the engine
compartment on the passenger’s side of the vehicle,
next to the upper underhood fuse block. See
Engine Compartment Overview on page 5-12for
more information on location.

4. Gently pull the headlamp assembly away from the
vehicle and remove the electrical connector.
5. Remove the round dust caps to gain access to
the bulbs.6. Turn the old bulb counterclockwise and remove it
from the retaining ring by gently pulling it away
from the headlamp.
7. Remove the electrical connector from the bulb by
raising the lock tab and pulling the connector away
from the bulb’s base.
8. Install the electrical connector to the bulb.
9. Install the new bulb by inserting the smallest tab on
the bulb base into the matching notch in the
retaining ring. Turn the bulb a quarter-turn clockwise
until it stops.
10. Reverse Steps 1 through 5 to reinstall the headlamp
assembly. Then, check the lamps.
