1994 CHEVROLET BLAZER warning

Downloaded from www.Manualslib.com manuals search engine If the differential is cold, add enough lubricant to raise the level to 1/2 inch
(12 mm) below the filler plug hole.
What to use
Refer to the Maintenance Schedule to determine what kind of lubricant to
use.
See “Recommended Fluids and Lubricants” in the Index.
Engine Coolanr
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.
The proper coolant for your vehicle will:
0 Give freezing protection down to -20 “F (-29”C), or -34°F (-37°C) in
Give boiling protection up to 258°F (125°C).
Canada
and for
vehicles with the cold climate option.
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.
What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 6038-M,” which won’t damage
aluminum parts.
You can use a recycled coolant conforming to “GM
Specification 6038-M,” with a complete coolant flush and refill. If you use
this mixture, you don’t need to add anything else.

Downloaded from www.Manualslib.com manuals search engine To Check Brake Fluid
You can check the
brake fluid without
taking off the cap. Just
look at the windows
on the brake fluid
reservoir.
The fluid levels should be above
“MIN.” If they aren’t, have your brake
system checked to see if there
is a leak.
After work is done on the brake hydraulic system, make sure the levels are
above
“MIN” and below the top of each window.
What to Add
When you do need brake fluid, use only DOT-3 brake fluid - such as
Delco Supreme
II@ (GM Part No.1052535). Use new brake fluid from a
sealed container only, and always clean the brake fluid reservoir cap before
removing it.
NOTICE:
0 Don’t let someone put in the wrong kind of fluid. For
example, just a few drops of mineral-based oil, such
as engine
oil, in your brake system can damage brake system parts so
badly that they’ll have to be replaced.
0 Brake fluid can damage paint, so be careful not to spill brake
fluid on your vehicle.
If you do, wash it off immediately. See
“Appearance Care” in the Index.
Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a high-pitched
warning sound when the brake pads are worn and new pads are needed. The
sound may come and go or be heard all the time your vehicle is moving
(except when you are pushing on the brake pedal firmly).

Downloaded from www.Manualslib.com manuals search engine If you ever replace your tires with those not having a TPC Spec number,
make sure they are the same size, load range, speed rating and construction
type (bias, bias-belted or radial) as your original tires.
Uniform Tire Quality Grading
The following information relates to the system developed by the United
States National Highway Traffic Safety Administration which grades tires
by treadwear, traction and temperature performance. (This applies
only to
vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the
tire when tested under controlled conditions on a specified government test
course. For example, a tire graded
150 would wear one and a half (1 1/2)
times as well on the government course as a tire graded 100. The relative
performance of tires depends upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in
driving habits, service practices and differences
in road characteristics and
climate.
Traction - A, B, C
The traction grades, from highest to lowest are: A, B, and C. They represent
the tire’s ability to stop on wet pavement as measured under controlled
conditions on specified government test surfaces
of asphalt and concrete. A
tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based
on braking
(straight-ahead) traction tests and does
not include cornering (turning)
traction.
6-46

Downloaded from www.Manualslib.com manuals search engine Temperature - A, B, C
The temperature grades are A (the highest), B, and C, representing the tire’s
resistance to the generation
of heat and its ability to dissipate heat when tested
under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire failure.
The grade
C corresponds to a level of performance which all passenger car
tires must meet under the Federal Motor Vehicle Safety Standard\

No. 109.
Grades B and A represent higher levels of performance on the laboratory test
wheel
than the minimum required by law.
Warning: The temperature grade for this tire
is established for a tire that is
properly inflated and not overloaded. Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat
buildup and possible tire failure.
These grades are molded on the sidewalls
of passenger car tires.
While the tires available as standard or optional equipment on General
Motors vehicles may vary
with respect to these grades, all such tires meet
General Motors performance standards and have been approved for use on
General Motors vehicles. All passenger type
(P Metric) tires must conform
to Federal safety requirements
in addition to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced carefully at the
factory to give you the longest tire life and best overall performance.
In most cases, you
will not need to have your wheels aligned again.
However,
if you notice unusual tire wear or your vehicle pulling one way or
the other, the alignment may need to be reset. If you notice your vehicle
vibrating when driving on
a smooth road, your wheels may need to be
rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted. If wheel nuts keep
coming loose, the wheel, wheel bolts, and wheel nuts should be replaced. If
the wheel leaks air, replace
it (except some aluminum wheels, which can
sometimes
be repaired). See your GM dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load carrying capacity, diameter,
width, offset, and be mounted the same way as the one
it replaces.

NOTICE:
If your vehicle has P235/75R15 size tires, don’t use tire chains;
they can damage your vehicle.
If you have other size tires, use tire chains only where legal and
only when you must. Use only
SAE Class “S” type chains that
are the proper size for your tires. Install them on the drive axle
tires (four-wheel-drive vehicles can use chains on both axles)
and tighten them
as tightly as possible with the ends securely
fastened. Drive slowly and follow the chain manufacturer’s
instructions.
If you can hear the chains contacting your vehicle,
stop and retighten them.
If the contact continues, slow down
until it stops. Driving too fast with chains on will damage your
vehicle.

t
Remember, cleaning products can be hazardous. Some are toxic. Others can
burst into flame if
you strike a match or get them on a hot part of the
vehicle. Some are dangerous if
you breathe their fumes in a closed space.
When you use anything from a container
to clean your vehicle, be sure to
follow the manufacturer’s warnings and instructions. And always open your
doors or windows when you’re cleaning the inside.
