1998 CADILLAC CATERA engine overheat

Downloaded from www.Manualslib.com manuals search engine What to Use
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.

If you need more coolant, add the proper Dm-COOL@
coolant mixture at the surge tank, but only when the
engine is cool.
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
Surge Tank Pressure Cap
NOTICE:
The surge tank cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating.

If the surge tank pressure cap needs to be replaced, a
Thermostat
When replacing the pressure cap, make sure it is tight.
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
If the thermostat needs to be replaced, a GM thermostat
is recommended.

the wiper
arm to engage the “J” hooked end on the
wiper blade assembly. Pull up on the assembly to
lock it into place.
Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service, see
your Catera Warranty booklet for details. Poorly maintained and improperly
used tires
are dangerous.
Overloading your tires can cause overheating
as a result of too much friction. You could
have
an about and a serious accident. See
‘Zoading Your Vehicle’’ in the Index.
Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
cut, punctured or broken by
a sudden
impact
-- such as when you hit a pothole.
Keep
tires at the recommended pressure.
Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.
See “Inflation
-- Tire Pressure’’ in this section
for inflation pressure adjustment for higher
speed driving.
Overinflated tires are more likely to be

Add-on Electrical Equipment
I NOTICE:
Don’t add anything electrical to your vehicle
unless you check with your dealer first. Some electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment
can keep other components from working as
they should.
Headlamp Wiring
The headlamp wiring has several fuses which are
powered by a MaxiFuse@. An electrical overload will
cause the lamps to go on and off, or in some cases to
remain
off. If this happens, have the headlamp wiring
checked right away.
MaxiFuse is a registered trademark of Little Fuse
Incorporated.
Windshield Wiper Fuses
If the windshield wiper motor overheats due to heavy
snow, etc., the wipers will stop until the motor cools. If
the overload is caused by some electrical problem, be
sure to have it fixed.
Your vehicle has an air bag system. Before attempting
to
add anything electrical to your vehicle, see “Servicing
Your Air Bag-Equipped Vehicle” in the Index.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is
too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.
