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,
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.

In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
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.

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.
Checking Engine Oil
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.

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:

6. Take out the air filter and remove any loose debris
that may be found laying
in the air cleaner base.
7. Install a new air filter element. See “Normal

operating temperature, which is
180" F to 200" F
(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.

With the parking brake applied, place the shift lever
in PARK

With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position the shift
lever in PARK (P).
Let the engine run at idle for three to five minutes.
Then, without shutting
off the engine, follow these steps: 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

Downloaded from www.Manualslib.com manuals search engine Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL TM (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your
vehicle for
5 years or 100,000 miles (166 000 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:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
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 (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.
(To order a service manual, see
“Service and Owner Publications” in the Index.)

Downloaded from www.Manualslib.com manuals search engine 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.
If you have to add coolant more than four times a year,
have 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.

The surge tank is located next to the engine block on the

lhrning 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 (60 mm) below
the base
of the fill neck. Use a flashlight as necessary to
see into the tank..
