1995 CHEVROLET BLAZER service

Downloaded from www.Manualslib.com manuals search engine When your vehicle is being towed, have the ignition key off. The steering
wheel should be clamped in a straight-ahead position with a clamping
device designed for towing service. Do not use the vehicle’s steering
column lock
for this. The transmission (either automatic or manual) should
be
in NEUTRAL (N) and the transfer case (either manual shift or electronic
shift), if you have one, should be in
2HI. The parking brake should be
released.
Don’t have your vehicle towed
on the rear wheels, unless you have to. If the
velucle must be towed
on the rear wheels, don’t go more than 35 mph (56
Mh) or farther than 50 miles (80 km) or your transmission will be
damaged. If these limits must be exceeded, then the rear drive wheels have
to be supported on a dolly.
Don’t have your vehicle towed with the wheels in contact with the ground if
it has all-wheel drive. If your vehicle has the all-wheel-drive option,
it can
only be towed with all four wheels off the ground. If the vehicle must be
towed with wheel lift equipment, then either the front or rear wheels must
be supported
on a dolly or the vehicle must be transported on a flatbed
carrier.

If you get the overheat warning but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high speed driving.
0 Idle for long periods in traffic.
e Tow a trailer. See "Driving on Grades" in the Index.
If
YOU get the overheat warning with no sign of steam, try this for a minute
or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan speed and open the
window as necessary.
3. If you're in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the
highest gear while driving
- AUTOMATIC OVERDRIVE (@) or
DRIVE (D) for automatic transmissions.
If you no longer have the overheat warning, you can drive. Just \
to be safe,
drive slower for about ten minutes.
If the warning doesn't come back on,
you
can drive normally.
If the warning continues, pull over, stop, and park your vehicle \
right away.
If there's still no sign of steam, push the accelerator until the engine speed is
about twice as fast
as normal idle speed. Bring the engine speed back to
normal idle speed after two or three minutes. Now
see if the warning stops.
But then, if you still have the warning,
turn oflthe engine and get everyone
out
of the vehicle until it cools down.
You may decide not to lift the hood but to get service help right away.

When you decide it's
safe to lift the hood,
here's what you'll
see:
A. Coolant recovery
B. Radiator pressure C. Engine fan tank
cap

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.

Downloaded from www.Manualslib.com manuals search engine Doing Your Own Service Work
If you want to do some of your own service work, you’ll want to get the
proper
GM Service Manual. It tells you much more about how to service
your vehicle than this manual can.
To order the proper service manual, see
“Service Publications” in the Index.
You should keep a record with all parts receipts and list the mileage and the
date
of any service work you perform. See “Maintenance Record” in the
Index.
I NOTICE:
If you try to do your own service work without knowing enough
about it, your vehicle could be damaged.
Fuel
Use regular unleaded gasoline rated at 87 octane or higher. Use premium
unleaded gasoline rated at 91 octane or higher for high power performance,
when towing a trailer or with a high payload requirement.
But when
operating with a light load as a normal condition, you may use middle grade
or regular unleaded gasolines.
6-2 0

Downloaded from www.Manualslib.com manuals search engine The gasoline you use should meet specifications ASTM D4814 in the
United States and
CGSB 3.5-92 in Canada. These fuels should have the
proper additives,
so you should not have to add anything to the fuel.
In the United States and Canada, it’s easy to be sure you get the right kind
of gasoline (unleaded). You’ll see
UNLEADED right on the pump. And
only unleaded nozzles will fit into your vehicle’s filler neck.
Be sure the posted octane is at least
91 for premium, 89 for middle grade
and 87-for regular.
If the octane is less than 87, you may get a heavy
knocking noise when you drive. If it’s bad enough,
it can damage your
engine.
If you’re using fuel rated at 91 octane or higher and you still hear heavy
knocking, your engine needs service. But don’t
worry if you hear a little
pinging noise when you’re accelerating
or driving up a hill. That’s normal,
and you don’t have to buy a higher octane fuel to get rid of it. It’s the heavy,
constant knock that means you have a problem.
What about gasoline with blending materials that contain oxygen
(oxygenates), such as
MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.” Fuel that is no more than 15%
MTBE is fine for your vehicle.
Ethanol is ethyl or grain alcohol. Properly-blended fuel that is no more than
10% ethanol is fine for your vehicle.
Methanol is methyl or wood alcohol.
~ NOTICE:
1 Fuel that is more than 5% methanol is bad for your vehicle.
I Don’t use it. It can corrode metal parts’in your fuel system and
1 also damage plastic and rubber parts. That damage wouldn’t b\
e
1 covered under your warranty. And even at 5% or less, there
~ must be “cosolvents” and corrosion preventers in this fuel\
to
~ help avoid these problems.

Downloaded from www.Manualslib.com manuals search engine Gasolines for Cleaner Air
Your use of gasoline with deposit control additives will help preven\
t
deposits from forming in your engine and fuel system. That hel\
ps keep your
engine
in tune and your emission control system working properly. It’s \
good
for your vehicle, and you’ll be doing your part for cleaner air.
Many gasolines are now blended with oxygenates. General Motors
recommends that you use gasolines with these blending materials, such as
MTBE and ethanol. By doing so, you can help clean the air, especially in
those parts of the country that have high carbon monoxide levels.
In addition, some gasoline suppliers are now producing reformulated
gasolines. These gasolines are specially designed to reduce vehicle
emissions. General Motors recommends that you use reformulated gasoline.
By doing
so, you can help clean the air, especially in those parts of the
country that have high ozone levels.
You should ask your service station operators if their gasolines contain
deposit control additives and oxygenates, and
if they have been
reformulated
to reduce vehicle emissions.
Fuels in Foreign Countries
If you plan on driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can corrode,
and your engine oil can deteriorate quickly. Your vehicle’s oxygen sensor
will be damaged. All of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be driving.
You can also write us at the following address for advice. Just tell us where
you’re going and give your Vehicle Identification Number (VI\
N).

If your vehicle has four-wheel drive, you will have a remote oil filter. There
is a special access door in the steering linkage shield assembly located under
the radiator support. Twist the screw to lock or unlock the door.
Engine Coolant Heater
An engine coolant heater can be a big help if you have to park outside in
very cold weather,
0°F (-18 “C) or colder. If your vehicle has this option,
see “Engine Coolant Heater” in
the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer? Don’t let used oil stay
on your skin for very long. Clean your skin and nails with soap and water,
or a good hand cleaner. Wash or properly throw away clothing or rags
containing used engine oil. (See the manufacturer’s warnings about the use
and disposal of oil products.)
Used oil can be a real threat to the environment. If you change your own oil,
be sure to drain all free-flowing oil from the filter before disposal. Don’t
ever dispose of oil by putting it in the trash, pouring
it on the ground, into
sewers, or into streams or bodies of water. Instead, recycle it by taking
it to
a place that collects used oil. If you have a problem properly disposing of
your used oil, ask your dealer, a service station or a local recycling center
for help.
Air Cleaner
To remove the rectangular air cleaner filter for the 4.3L (VIN W) engine,
open both clamps and push the rear
of the air cleaner back toward the rear
of the engine compartment to change the filter.
