catch fire and you
or others could be burned.
Use a 50/50 mixture of clean water and
DEX-COOL@ coolant.
1 NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
I A 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.
I. You can remove the coolant surge tank pressure
cap when the cooling system, including the coolant
surge tank pressure cap and upper radiator hose,
is no longer hot. Turn the pressure cap slowly
counterclockwise until it first 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.

engine and
let it run until you can feel the upper
radiator hose getting
hot. Watch out for the engine
cooling fans.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level
is lower, add
more
of the proper mixture to the coolant surge tank
until the level reaches about 2.5 inches (6.4 cm)

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.
When to Add Engine Oil
If the oil is at or below the ADD line, then you’ll need
to add at
least one quart of oil. But you must use the
right kind. This part explains what kind of oil to use. For
crankcase capacity,
see “Capacities and Specifications”
in the
Index.
NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
A
The oil fill cap is located
behind the radiator
on the
passenger’s side
of the
engine.
Turn the cap to the
left to remove it.
Be sure to
fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you’re through.

The black transaxle fluid cap is located next to the
radiator hose and below the air cleaner assembly on
the driver’s side
of the engine. Remove the air
cleaner assembly
so you can reach the transaxle fluid
cap. The assembly is attached to the vehicle by two
fasteners. Lift up on
the air cleaner assembly to
remove it.
Find the transaxle fluid cap and turn it to the left
to remove.
3. Pull out the dipstick and wipe it with a clean rag or
paper towel.
then pull it back out again.

5. Check both sides of the dipstick, and read the
lower level. The fluid level must be in the
cross-hatched area.
6. If the fluid level is in the acceptable range, push
the dipstick back
in all the way. Replace the air
cleaner assembly.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind
of transaxle fluid to use. See “Recommended Fluids
and Lubricants”
in the Maintenance Schedule booklet.

.
The surge tank is located next to the engine block on the
passenger's side
of the engine.
The cooling system is under a
lot of pressure when it
is hot. If the CHECK COOLANT LEVEL message
appears
on the Driver Information Center (DIC), you
will need to add coolant.
A 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.
When your engine is cold. the coolant level should be at
the full cold mark, which
is 2.5 inches (6.4 cm) below
the base
of the fill neck. Use a flashlight as necessary to
see into the tank.

Downloaded from www.Manualslib.com manuals search engine Adding Coolant
If you need more coolant, add the proper DEX-COOL@
coolant mixture ut the surge tank, but only when the
engine
is cool.
I A 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.
When replacing
the pressure cap, make sure it is tight.
Surge Tank Pressure Cap
NOTICE:
The surge tank cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed
to prevent coolant loss and possible engine
damage
from overheating. Be sure the arrows
on the cap line up.
If the surge tank pressure cap needs to be replaced, a
GM cap is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow
of coolant through the radiator until the coolant
reaches a preset temperature.
If your thermostat needs to be replaced. a GM
thermostat is recommended.
