2003 Oldsmobile Alero heating

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.
If the surge tank is empty, a special fill
procedure is necessary. See
Engine Overheating
on page
5-26 and “How to Add Coolant to the Coolant
Surge Tank under
Cooling System on page 5-28
for instructions.
Engine Overheating
You will find a coolant temperature gage and a low
coolant warning light on your vehicle’s instrument panel.
See
Engine Coolant Temperature Gage on page 3-31
and Low Coolant Warning Light on page 3-31.
If Steam Is Coming From Your Engine

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
hand-tight.

Heater a _.__ . -ldiatoL -.oses, and other engine
parts, can be very hot. Don’t touch them. If you
do, you can be burned.
Don’t run the engine if there
is a leak. If you
run the engine, it could lose all coolant. That
could cause an engine fire, and you could be
burned. Get any leak fixed before you drive the
vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fans are running.
If the engine is overheating, both fans should be
running.
If they aren’t, your vehicle needs service.
Notice: Engine damage from running your engine
without coolant isn’t covered by your warranty.
Notice: When adding coolant, it is important that
you use only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL
is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the engine
coolant will require change sooner
- at 30,000 miles
(50 000 km) or 24 months, whichever occurs first.
Damage caused by the use of coolant other
than DEX-COOL@ is not covered by your new vehicle
warranty.
How to Add Coolant to the Coolant
Surge Tank
Notice: This vehicle has a specific coolant fill
procedure. Failure to follow this procedure could
cause your engine to overheat and be severely
damaged.
If you haven’t found a problem yet, check to see
if
coolant is visible in the surge tank. If coolant is visible
but the coolant level isn’t at or above the
FULL
COLD mark, 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. See Engine Coolant on page 5-23 for more
information.

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer.
If you ever have questions
about your tire warranty and where to obtain service,
see your Oldsmobile Warranty booklet for details.

Poorly maintained and improperly used tires
are dangerous.
0 Overloading your tires can cause
overheating as a result of
too much
friction. You could have an air-out and a
serious accident. See “Loading Your
Vehicle” in the Index.
CAUTION: (Continued)
4 inflated tires pose -..? same c ~ lger
I as overloaded tires. The resulting accident
I could cause serious injury. Check all tires
frequently to maintain the recommended
~ pressure. Tire pressure should be checked
when your tires are cold.
~ Overinflated tires are more likely to be
cut, punctured or broken by a sudden
~ impact - such as when you hit a pothole.
Keep tires at the recommended pressure.
~ Worn, old tires can cause accidents. If
I
I
your tread is badiy WBTii, or if your tires
have been damaged, replace them.
