1998 CHEVROLET BLAZER engine overheat

Downloaded from www.Manualslib.com manuals search engine A 50/50 mixture of water and DEX-COOL@ coolant 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.
0 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.
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.
A 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 water and
DEX-COOL@ coolant.

Downloaded from www.Manualslib.com manuals search engine 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.
I 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.
Checking Coolant
When your engine is cold, the coolant level should be at
ADD, or a little higher. When your engine is warm, the
level should be
up to FULL HOT, or a little higher.
Adding Coolant If you need more coolant, add the proper
DEX-COOL@
coolant mixture at the coolant recovery tank.

lhrning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids
to blow out and burn you badly.
With the coolant recovery tank, you will almost
never have to add coolant at the radiator.
Never turn the radiator pressure cap
-- even a
little
-- when the engine and radiator are hot.
Add coolant mixture at the recovery tank, but be careful
not
to spill it.
- v:
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.
I NOTICE:
Your radiator 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. Be sure the arrows on the cap
line up with the overflow tube
on the radiator
filler neck.

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 airout and a serious accident.
See
“Loading 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.
Overinflated tires are more likely to be
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.
Inflation -- Tire Pressure
The CertificatiodTire label, which is on the driver’s
door edge, above the door latch, shows the correct
inflation pressures for your tires when they’re cold.
“Cold” means your vehicle has been sitting
for at least
three hours or driven
no more than 1 mile (1.6 km).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right. It’s not.
If your tires
don’t have enough air (underinflation), you can
get the following:
0 Too much flexing
0 Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.

The headlamp wiring is protected by an internal
circuit breaker. An electrical overload will cause the
lamps to go
on and off, or in some cases to remain off.
If this happens, have your headlamp wiring checked
right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem, be
sure to get it fixed.
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. The
wiring circuits in your vehicle are protected from
short circuits by a combination
of fuses and circuit
breakers. This greatly reduces the chance of fires
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band
is broken or melted, replace the fuse. Be sure you
replace
a bad fuse with a new one of the identical size
and rating.
If
you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without -- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as
you can.
