engine coolant CADILLAC CATERA 1997 1.G User Guide

Downloaded from www.Manualslib.com manuals search engine 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.
I A C A UTION:
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.
If there seems to be no leak, with the engine on, check to
see if the electric engine fans are running. If the engine
is overheating, both fans should be running. If they
aren’t, your vehicle needs service.

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 water (preferably distilled) 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 “Engine
Coolant” in the Index for more information.)
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.

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@ coolant.
I 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.

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.

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 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 the
KALTKOLD line (seam).

Downloaded from www.Manualslib.com manuals search engine If you get gasoline on yourself and then
something ignites
it, you could be badly burned.
Gasoline can spray out on you
if you open the
fuel filler cap too quickly. This spray can happen
if your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any “hiss” noise to stop. Then unscrew
the cap all the
way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See “Cleaning the
Outside of Your Catera” in the Index.
When
you put the cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make sure
you fully install the cap.
Checking Things Under the Hood
A CAC-ION:
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.
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.

The air cleaner is located behind the headlamps on the
passenger’s side
of the engine. Be sure the engine has
cooled before following these steps
to replace the air filter.
I
1. Unhook the five clips that attach the air cleaner lid to
the housing.
2. 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.

Downloaded from www.Manualslib.com manuals search engine 4. Lift the lid, take out the air filter and remove any
loose debris that may be found laying in the air
cleaner base.
5. Install a new air filter element. See “Normal
Maintenance Replacement Parts”
in the Index.
To reinstall the air cleaner assembly, replace the air
cleaner lid, reattach the five clips, replace the air intake
tube and tighten the clamp. Return the coolant surge
tank hose
to its proper position.
Refer
to the Maintenance Schedule to determine when to
replace the air filter. See
“Scheduled Maintenance Services” in the
Maintenance Schedule booklet.
‘
A CAUTION:
Operating the engine with the air cleaner off can
cause you or others to be burned. The air cleaner
not only cleans the air, it stops flames
if the
engine backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it off, and be careful working on the engine with
the air cleaner off.
NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage
it. Always
have the air cleaner in place when you’re driving.
