coolant CADILLAC CATERA 2000 1.G User Guide

5-13
The coolant level should be at or slightly above the
KALT/COLD 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.
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.
NOTICE:
Engine damage from running your engine
without coolant isn't covered by your warranty.

5-14
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.
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.
How to Add Coolant to the Coolant
Surge Tank
If you haven't found a problem yet, but the coolant level
isn't at the KALT/COLD line (seam), 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 ªEngine Coolantº in the
Index for more information.)

5-15
CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the coolant
surge tank pressure cap
-- even a little -- they
can come out at high speed. Never turn the cap
when the cooling system, including the coolant
surge tank pressure cap, is hot. Wait for the
cooling system and coolant surge tank pressure
cap to cool if you ever have to turn the
pressure cap.

5-16
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 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, drinkable water
and DEX
-COOL
coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So use the recommended coolant.
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.

5-17
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 (left) 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.

5-18
3. Then fill the coolant surge tank with the proper
mixture, to the KALT/COLD 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 KALT/COLD line (seam).

Here you will find information about the care of your vehicle. This section begins with service and fuel information,
and then it shows how to check important fluid and lubricant levels. There is also technical information about your

Checking Things Under the Hood
CAUTION:
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
CAUTION:
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not to drop or spill
things that will burn onto a hot engine.
Hood Release
Pull the lever inside the
vehicle to open the hood.
It is located on the
lower left side of the
instrument panel.
Then go to the front of the vehicle and find the
secondary hood release which is located above the front
grille. Lift up on the release lever as you raise the hood.

6-10
When you open the hood, you'll see:
A. Coolant Fill Location
B. Engine Air Cleaner/Filter
C. Passenger Compartment
Air FilterD. Engine Oil Fill Location
E. Engine Oil Dipstick Location
F. Windshield Washer FluidG. Brake Master Cylinder
H. Power Steering Fluid
I. Battery
Before closing the hood, be sure all filler caps are on properly. Then pull the hood down and close it firmly.

1. Unhook the five clips that attach the air cleaner lid
to the housing. You may need to use a screwdriver
to help you unhook the clips.
2. With a screwdriver, loosen the retaining clamp on
the air intake tube and then disconnect the tube as
shown by the arrow above.
3. Move the hose going to the coolant surge tank
out of the way so the air cleaner lid can be lifted.4. Lift the lid, take out the air filter and remove any
loose debris that may be found lying in the air
cleaner base.
5. Install a new air filter element. See ªNormal
Maintenance Replacement Partsº in the Index.
