Windshield Washer
A CAUTION:
In freezing weather, don’t use your washer until
the windshield
is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
NOTICE:
When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other parts of the washer system.
Also,
water doesn’t clean as well as washer fluid.

The coolant level should be indicated by a CHECK
COOLANT LEVEL message on the Driver Information
Center.
If it isn't, you may have a leak in the radiator
hoses, heater
hoses, radiator, water pump or somewhere
else in the cooling system.
A CAUTION:
Heater and radiator hoses, 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.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
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.

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 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.

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
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 mix to the coolant surge tank
until the level reaches about
2.5 inches (60 mm)
below the base of the filler neck.
5. Then replace the pressure cap. Be sure the arrows on
the pressure cap line up like this.
Start
the engine and allow it to warm up. If the CHECK
COOLANT LEVEL message does not appear on the
Driver Information Center, coolant is at the proper fill
level.
If a CHECK COOLANT LEVEL message does
appear, repeat Steps 1 to
3 or see your dealer.

A CHECK OIL LEVEL message will appear when
the engine oil
is approximately a quart low. If the
message
is displayed, check the dipstick level and add
oil
as needed.
It's a good idea to check your engine oil every time you
get fuel.
In order to get an accurate reading, the oil must
be
warm and the vehicle must be on level ground. The engine oil dipstick
is
located behind
the radiator
on the driver's side of the
engine. The black handle
says ENGINE OIL on it.
Turn off the engine and
give the oil a few minutes
to
drain back into the oil
pan. If you don't, the oil
dipstick
might not show
the actual level.

The oil fill cap is located
behind the radiator
on the
L
~ passenger’s side of the
~ engine. Turn the cap
1 counterclockwise to
remove.
Just 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.
What Kind of Oil to Use
Oils recommended for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute
(API). Do not use any oil which
does not carry this Starburst symbol.
If you change your own
oil, be sure you use oil
that has the Starburst
symbol on the front
of the
oil container. If you have
your oil changed for you,
be sure the oil put into
your engine
is American
Petroleum Institute certified
for gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

Downloaded from www.Manualslib.com manuals search engine Wait at least 30 minutes before checking the transaxle
fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180°F to 200°F
(82°C to 93°C).
Get the vehicle warmed up by driving abut 15 miles (24 km)
when outside temperatures are above 50°F (10°C). If it's
colder
than 50°F (lO"C), you may have to drive longer.

The cooling system in your vehicle is filled with new
DEX-COOL (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your vehicle for
5 years or 100,000 miles (166 0o0 km),
whichever occurs first.
The following explains your cooling system and how
to
add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating” in
the Index.
A 50/50 mixture of water and the proper coolant for
your Cadillac will:
Give freezing protection down to -34°F (-37 O C).
Give boiling protection up to 265 “F (129 “C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant 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.
What
to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL (orange-colored,
silicate-free) antifreeze that meets
GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need
to add anything else.
A special procedure is required for adding sealer; see the
Cadillac service manual.

“Service and Owner Publications”
in the Index.)

A CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or
some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water
or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you
or
others could be burned. Use a 50/50 mix of clean
water and
DEX-COOL (orange-colored,
silicate-free) antifreeze.
NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by your
warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
[f you have to add coolant more than four times a year,
lave your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
