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.

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.
S. Then replace the pressure cap. Be sure the arrows on
the pressure cap line up like this. c
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.

behind the radiator on the
passenger’s side
of the
engine. Turn the cap
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 throtlgh. 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
(APT). Do not use any oil which
does not carry this Starburst symbol.
_- .. U 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,

located near the radiator hose (not shown) and the
other latch
is located next to the IAT sensor.
5. Pivot the air cleaner and air duct assembly towards
the front
of the vehicle. Remove the cover.
6. Take out the air filter and remove anv loose debris
that may
be found laying in the air cieaner base.
7. Install a new air filter element. See “Normal

fluid level if you have been driving:
When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
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 OF to 200 OF
(82°C to 93°C).
Get the vehicle warmed up by driving about 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.

Let the engine run at idle for three to five minutes. Then,
without shutting off the engine, follow these steps:
1. 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. Simply lift up on the air cleaner assembly
to remove it. Find the transaxle fluid cap and turn it
counterclockwise to remove. Pull out the dipstick
and wipe it with
a clean rag or paper towel.
2. Push it back in all the way. wait three seconds and

The cooling system in your vehicle is filled with new
DEX-COOL rm (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain
in your
vehicle
for 5 years or 100,000 miles (1 66 000 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:
0 Give freezing protection aown to -34°F (-37°C).
0 Give boiling protection up to 265 “F (129 O C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If dicated 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.
(To order a service manual, see
“Service and Owner Publications”
in the Index.)
