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. See
Engine
Compartment Overview on
page 5-12
for more
information on location.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the COLD
mark or a little higher. When your engine is warm,
the level should be up to the HOT mark or a little higher.
Adding Coolant
If you need more coolant, add the proper DEX-COOLž
coolant mixtureat the coolant recovery tank,but be
careful not to spill it.
If the coolant recovery tank is completely empty, add
coolant to the radiator. See
Engine Overheating
on page 5-29.
{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 Ð even a little Ð when the engine and
radiator are hot.
{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.
Occasionally check the coolant level in the radiator.
For information on how to add coolant to the radiator,
see
Cooling System on page 5-32.

How to Add Coolant to the Radiator
Notice:Your engine has a speci®c 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 on the passenger's side of the
vehicle, near the diagonal cross brace. SeeEngine
Compartment Overview on page 5-12for more
information on location.
1. You can remove the radiator pressure cap when
the cooling system, including the radiator pressure
cap and upper radiator hose, is no longer hot.
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.
5-37

2. Then keep turning the pressure cap, but now push
down as you turn it. Remove the pressure cap.
{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.
A. 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.
B. Lift the engine cover shield at the front, slide
the catch tab out of the engine bracket and
remove the cover shield.
C. 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. Fill the radiator with the proper DEX-COOLž
coolant mixture, up to the base of the ®ller
neck. SeeEngine Coolant on page 5-26for more
information about the proper coolant mixture.
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 you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
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.To uncover the remote positive (+) terminal, lift the
plastic cap. You should always use the remote
positive (+) terminal instead of the positive (+)
terminal on the battery.
