1998 CADILLAC CATERA radiator

Downloaded from www.Manualslib.com manuals search engine An electric engine cooling fan under the hood can
start up even when the engine is not running and
can injure you. Keep hands, clothing and tools
away from any underhood electric fan.
If the coolant inside the coolant surge tank is boiling,
don’t
do anything else until it cools down.
I
The coolant level should be at or slightly above the
KALTKOLD line (seam). 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.
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.
I NOTICE: I
Engine damage from running your engine
without coolant isn’t covered by your warranty.
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.

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 mixture will. 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 wouldn’t
get the overheat warning. Your engine could
catch fire and you
or others could be burned.
Use
a 50/50 mixture of clean water and
DEX-COOL@ coolant.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
I 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.

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.
2. Then keep turning the pressure cap slowly, and
remove it.

mixture, up to the KALTKOLD line (seam). 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 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 mixture to the coolant surge tank
until the level reaches the KALTKOLD line (seam).

If the low oil level light on
the instrument panel comes
on, it means you need to
check your engine oil level
right away. For more information, see “Low Oil
Level Light”
in the Index.
You should check your engine oil level regularly; this is
an added reminder.
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
hose on the driver’s side
of
the engine. The yellow
looped handle helps to
identify 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.

Refer to the Maintenance Schedule to determine what
kind of lubricant to use. See “Recommended Fluids and
Lubricants” in the Maintenance Schedule booklet.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant.
This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240 000 krnb whichever occurs first, if you add only
DEX-COOL extended life coolant.
J
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 DEX-COOL’
coolant will:
a Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 OF (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
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.

Downloaded from www.Manualslib.com manuals search engine What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL@ coolant which
won’t damage aluminum parts.
If you use this mixture,
you don’t need to add anything else.
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 mixture will. 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 wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use
a 50/50 mixture of clean water and
DEX-COOL@ coolant.
NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your
warranty. Too much water
in the mixture 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.

Downloaded from www.Manualslib.com manuals search engine Checking Coolant
The surge tank is located behind the air cleaner on the
passenger’s side
of the engine.
The cooling system when hot is under a lot
of pressure.
If the low coolant warning light on the instrument panel
appears, you will need to add coolant.
= I
Turning 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 KALTKOLD line (seam).

If the light comes on, it
means you’re low on
engine coolant.
