1995 CHEVROLET BLAZER Owners Manual

Downloaded from www.Manualslib.com manuals search engine If the coolant inside the coolant recovery tank is boiling, don’\
t do anything
else until
it cools down.
The coolant level should be at the
ADD mark. 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.
NOTICE:
Engine damage from running your engine without coolant isn’t \
covered
by your warranty.
If there seems to be no leak, start the engine again. See if the fan speed
increases when idle speed is doubled
by pushing the accelerator pedal down.
If it doesn’t, your vehicle needs service. Turn off the engine.

If you haven’t found a problem yet, but the coolant level isn’t \
at ADD, add a
50/50 mixture of clean water (preferably distilled) and a proper antifreeze at
the coolant recovery tank. (See “Engine Coolant’’ in the Index for more
information about the proper coolant
mix.) ..
NOTICE:
In cold weather, water can freeze and crack the engine, radiat\
or,
heater core and other parts. Use the recommended coolant.

If the overheat warning continues, there’s one more thing you can try. You
can add the proper coolant mix directly to the radiator but be sure the
cooling system
is cool before you do it.

1. You can remove the radiator pressure cap when the cooling system,
including the radiator pressure cap and upper radiator hose, is
no longer
hot. Turn the pressure cap slowly
to the 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.

as you turn it.
Remove the

with the proper
mix, up to the
base
of the filler

neck.
4. Then fill the coolant recovery
tank
to the ADD

6. Start the engine
and let it
run until
you can feel'the
upper radiator hose getting hot.
Watch out for the
engine fan.
7. By this time the coolant level inside the filler neck may be lower. If the
level is lower, add more of the proper mix through the filler neck unt\
il
the level reaches the base of the filler neck.
8. Then replace the
pressure cap. At
any time during
this procedure if
coolant begins to
flow out of the
filler neck,
reinstall the
pressure cap. Be
sure the arrows
on the pressure
cap line
up like
this.
Engine Fan Noise
This vehicle has a clutched engine cooling fan. When the clutc\
h is engaged, the fan spins faster to provide more air to cool the engine. \
In most every day
driving conditions the clutch
is not engaged. This improves fuel economy
and reduces fan noise. Under heavy vehicle loading, trailer tow\
ing and/or
high outside temperatures, the fan speed increases when
the clutch engages.
So you may hear an increase in fan noise. This is normal and should not be
mistaken
as the transmission slipping or making extra shifts. It is merely \
the
cooling system functioning properly. The fan will slow down when
additional cooling is not required and
the clutch disengages.
You may also hear this fan noise when you start the engine. It will go away
as the fan clutch disengages.

It’s unusual for a tire to “blow out” while you’re driving, especially if you
maintain your tires properly. If air goes out
of a tire, it’s much more likely to
leak out slowly. But
if you should ever have a “blowout,” here are a few tips
about what to expect and what
to do:
If a front tire fails, the flat tire will create a drag that pulls the vehicle
toward that side. Take your foot
off the accelerator pedal and grip the
steering wheel firmly. Steer to maintain lane position, then ge\
ntly brake to a
stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a skid and may
require the same correction you’d use in a skid. In any rear blowout, remove
your foot from
the accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be very bumpy and
noisy, but you can still steer. Gently brake to a stop, well
off the road if
possible.
If a tire goes flat,
the next part shows how to use your jacking equipment to
change
a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage by driving slowly to a
level place.
Turn on your hazard warning flashers.

t
The following steps will tell you how to use the jack and change a tire.
Your vehicle is equipped with work gloves and a plastic ground mat to assist
in the changing of a flat tire.
Jacking Equipment Storage
The jacking equipment you’ll need is stored along the driver’s rear wall. In
some cases,
you may have to remove the spare tire in order to reach the
jack.
To remove your jack
cover, pull
up on the
latch. Pull the wheel
blocks, jack and wheel
wrench
off.
