1995 CHEVROLET S10 engine oil

Downloaded from www.Manualslib.com manuals search engine I NOTICE:
Use only engine oil with the American Petroleum Institute Certified For Gasoline Engines “Starburst” symbol. Failure \
to
use the proper oil can result in engine damage not covered by
your warranty.
GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the
requirements for your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your GM dealer is ready to advise if you
think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 5 to 10 miles (8 to 16 km). This is particularly
important when outside temperatures are below freezing.
Most trips include extensive idling (such as frequent driving in stop and
go traffic).
You operate your vehicle in dusty areas or off-road frequently.
0 You frequently tow a trailer.
If any one of these is true for your vehicle, then
you need to change your oil
and filter every
3,000 miles (5 000 km) or 3 months - whichever comes
first.
If none of them is true, change the
oil and filter every 7,500 miles (12 500
km) or 12 months - whichever comes first.

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 (-1 8 O 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 round air cleaner filter for the 4.3L (VIN 2) engine, turn the
wing nuts counterclockwise. Remove the cover and change the filter. Care
should be taken during reassembly to ensure that the cover is on straight and
the wingnuts
are properly tightened.
= To avoid ingesting
dust in the engine, the
arrow on the air
cleaner lid should
point
to the front of
the engine.

Downloaded from www.Manualslib.com manuals search engine Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule to determine
when to change your fluid. See “Scheduled Maintenance Services” in the
Index.
How to Check
Because this operation can be a little difficult, you may choose to have this
done at your GM dealership Service Department.
If
you do it yourself, be sure to follow all the instructions here, or you could
get a false reading on the dipstick.
I NOTICE:
Too much or too little fluid can damage your transmission. Too
much can mean that some of the fluid could come out and fall\

on
hot engine parts or exhaust system parts, starting a fire. Be sure
to get an accurate reading if you check your transmission fluid.
Wait at least 30 minutes before checking the transmission fluid level if you
have been driving:
When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
0 In heavy traffic - especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal operating
temperature, which
is 180°F to 200°F (82°C to 93°C).
To check transmission fluid hot: Get the vehicle warmed up by driving
about
15 miles (24 krn) when outside temperatures are above 50°F ( 1 0°C).
If it’s colder than 50°F (lO”C), drive the vehicle in THIRD GEAR (D) until
the engine temperature gage moves and then remains steady for ten minutes.
Then follow the hot check procedures.

When to Check
A good time to have it checked is when the engine oil is changed. However,
the fluid in your manual transmission doesn't require changing.
How to Check
Because this operation can be a little difficult, you may choose to have this
done at your
GM dealership Service Department.
If you do it yourself, be sure to follow all the instructions here, or you could
get a false reading.
NOTICE:
Too much or too little fluid can damage your transmission. Too
much can mean that some of the fluid could come out and fall on
hot engine parts or exhaust system parts, starting a fire. Be sure
to get an accurate reading if
you check your transmission fluid.
Check the fluid level only when your engine is off, the vehicle is parked on
a level place and the transmission is cool enough for
you to rest your fingers
on the transmission case.
Then, follow these steps:
h
1. Remove the filler
Plug-
2. Check that the
lubricant level is
up to the bottom
of the filler plug
hole.
3. If the fluid level is good, install the plug and be sure it is fully seated. If
the fluid level is low, add more fluid as described in the next steps.

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 Index.
Engine Coolant
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:
Give freezing protection down to -34°F (-37 “C).
Give boiling protection up to 262°F (128 “C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
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,” or “GM Specification
6043-M’ with the 2.2L (LN2) Code 4 engine, which won’t damage
aluminum parts.
You can also use a recycled coolant conforming to “GM
Specification 603%”’ or “GM Specification 6043-M” with the 2.2L
(LN2) Code 4 engine. Use GM Coolant Supplement (Sealer) 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 NOTICE:
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.
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).
I NOTICE:
Continuing to drive with worn-out brake pads could result in
costly brake repair.
Some driving conditions or climates may Cause a brake squeal when the
brakes are
first applied or lightly applied. This does not mean something is
wrong with your brakes.
Your rear drum brakes don’t have wear indicators, but if you ever hear a
rear brake rubbing noise, have the rear brake linings inspected. Also, the
rear brake drums should be removed and inspected each time the tires are
removed for rotation or changing. When you have the front brakes replaced,
have
the rear brakes inspected, too.
Brake linings should always be replaced as complete axle sets.

Downloaded from www.Manualslib.com manuals search engine Lock Cylinders
To be sure your locks operate properly, they must be lubricated.
Refer
to the Maintenance Schedule to determine how often to lubricate them
and what type of lubricant to use.
You should not
use penetrating oils because they could wash out the factory
installed lubricant and cause the lock to bind. De-icers which contain
alcohol could also wash away the lubricant,
so be sure to lubricate the lock
after using a de-icer of this type.
Exhaust System
To help prevent damage to your exhaust system, do not continue to drive
your vehicle if you notice:
Engine misfiring
Loss of performance
Exhaust system components hanging lower than normal.
Loud exhaust system noises.
Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three-way Catalytic Converter
Your vehicle’s three-way catalytic converter is designed to reduce the
pollutants in your vehicle’s exhaust. Use only unleaded fuel in your vehicle.
If you use leaded fuel, you could damage your three-way catalytic converter
and other engine components.
Engine Control Module System
This system has an oxygen (02) sensor that helps keep your engine’s
air-fuel mixture at a proper level. Use only unleaded fuel in your vehicle. If
you use leaded fuel, you could damage your oxygen
(02) sensor and affect
your vehicle’s emissions.
Malfunction Indicator Lamp (SERVICE ENGINE
SOON)
This light on your instrument panel lets you know when your emission
system needs service. See “Malfunction Indicator Lamp” in the Index.

I NOTICE:
Be careful. A blow dryer may scorch the fabric.
0 Wipe with a clean cloth.
Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all. Some spots and
stains will clean off better with just water and mild soap.
If you need to use a solvent:
Gently scrape excess soil from the trim material with a clean, dull knife
or scraper. Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at the outside
of the
stain, “feathering” toward the center. Keep changing to a clean section
of the cloth.
0 When you clean a stain from fabric, immediately dry the area with a
blow dryer to help prevent a cleaning ring. (See the previous NOTICE.)
