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 FULL COLD mark,
add a 50/50 mixture ofclean, drinkable waterand
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 5-20for 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.
{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.

CAUTION: (Continued)
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: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 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 (left) about one-quarter of a
turn. If you hear a hiss, wait for that to stop. This
will allow any pressure still left to be vented out the
discharge hose.
2. Then keep turning the pressure cap slowly, and
remove it.

3. Fill the coolant surge tank with the proper
DEX-COOL®coolant mixture, to the COLD line.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 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 then reinstall the
pressure cap. If the coolant is not at the proper level
when the system cools down again, see your retailer.
Power Steering Fluid
The power steering fluid
reservoir is located toward
the front of the engine
compartment on the
driver’s side of the vehicle.
SeeEngine Compartment
Overview on page 5-12
for reservoir location.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid
unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid
To check the power steering fluid, do the following:
1. Turn the key off and let the engine compartment
cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the fluid level
on the dipstick.
The level should be at the “C” mark. If necessary, add
only enough fluid to bring the level up to the mark.
What to Use
To determine what kind of fluid to use, see
Recommended Fluids and Lubricants on page 6-13.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.

Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted
or corroded. If wheel bolts keep coming loose, the
wheel and wheel bolts should be replaced. If the wheel
leaks air, replace it (except some aluminum wheels,
which can sometimes be repaired). See your Saturn
Retailer if any of these conditions exist.
Your retailer will know the kind of wheel or wheel bolt
you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.
If you need to replace any of your wheels or wheel
bolts, replace them only with new Saturn original
equipment parts. This way, you will be sure to have the
right wheel and wheel bolts for your Saturn.{CAUTION:
Using the wrong replacement wheels or wheel
bolts on your vehicle can be dangerous. It
could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in
which you or others could be injured. Always
use the correct wheel and wheel bolts for
replacement.
Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance and tire or tire chain
clearance to the body and chassis.
SeeChanging a Flat Tire on page 5-62for more
information.
