CHEVROLET S10 1996 2.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine A 50/50 mixture of water and the proper coolant for
your vehicle 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
DEX-COOL (orange-colored, silicate-free)
coolant meeting GM Specification 6277M.
If silicated coolant 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. What to
Use
Use a mixture of one-half
clean water (preferably
distilled) and one-half DEX-COOL (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M’ which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need to add anything else.
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 mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, 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 mix of clean
water and
DEX-COOL (orange-colored,
silicate-free) antifreeze.

r
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair
cost wouldn’t be covered by your
warranty.
Too much water in the mix 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: I
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
LID to FULL HOT, or a little higher.

If you need more coolant, add the proper mix at the
coolant recovery tank.
1 A CAUTION:
Add coolant mix at the recovery tank, but be careful not
to spill
it.
Tbrning 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.
A CAUTION:
+-
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.

Downloaded from www.Manualslib.com manuals search engine Radiator Pressure Cap
NOTICE: - ~ I
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.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.

When the engine compartment is cool, unscrew the cap
and wipe the dipstick with a clean rag. Replace the cap
and completely tighten it. Then remove the cap again
and
look at the fluid level on the dipstick.
The level should be between the
ADD and FULL marks.
For the
LN2 engine, the fluid level should be at the C
mark. If necessary, add only enough fluid to bring the
level up
to the proper range.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid
to use. See “Recommended Fluids and
Lubricants” in the Index. Always use the proper fluid.
Failure to
use the proper fluid can cause leaks and
damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle
in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid
unless you suspect there is a leak
in the system or you hear
an unusual noise.
A fluid loss in this system could indicate
a problem. Have
the system inspected and repaired.

When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause the solution to freeze and damage your washer fluid tank and
other parts of the washer system. Also,
water doesn’t clean
as well as washer fluid.
Fill your washer fluid tank only
3/4 full
when it’s very cold. This allows for
expansion, which could damage the tank if
it is completely full.
Don’t use radiator antifreeze in your
windshield washer.
It can damage your
washer system and paint.

Brake Fluid
Your brake master cylinder reservoir is here. It is filled
with
DOT-3 brake fluid.
There are only two reasons
why the brake fluid level in the
reservoir might
go down. The first is that the brake fluid
goes down
to an acceptable level during normal brake
lining wear. When new linings
are put in, the fluid level
goes back up. The other reason
is that fluid is leaking out
of the brake system. If it is, you should have your brake
system fixed, since a leak means that sooner or later your
brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak.
If you add fluid
when your linings are worn,
then you’ll have too much
fluid when
you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work
is
done on the brake hydraulic system.
’ A CAUTION: I
If you have too much brake fluid, it can spill on
the engine. The fluid will burn if the engine is hot
enough. You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work
is done on the brake hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections”
in the Index.
6-31

Downloaded from www.Manualslib.com manuals search engine Checking 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 11 @ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only, and always clean the brake fluid
reservoir cap before removing it.
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake fluid.

Downloaded from www.Manualslib.com manuals search engine Brake Wear
NOTICE:
0 0 Using the wrong fluid can badly damage
brake system parts. 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. Don’t let someone put in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged.
Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care” in
the Index. Your
vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicatbrs 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).
The brake wear warning sound means that sooner
or later your brakes won’t work well. That could
lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
6-33

Downloaded from www.Manualslib.com manuals search engine 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.
Free movement of brake calipers and properly torqued
wheel nuts are necessary to help prevent brake
pulsation. When tires are rotated, inspect brake calipers
for movement, brake pads
for wear, and evenly torque
wheel nuts in the proper sequence to
GM specifications.
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.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be
a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
If your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
backing
up and firmly applying the brakes a few times.
Replacing Brake System Parts
The braking system on a modern vehicle is complex.
Its many parts have to be of top quality
and work well
together if the vehicle is to have really good braking.
Vehicles we design and test have top-quality
GM brake
parts
in them, as your vehicle does when it is new. When
you replace parts of your braking system
-- for example,
when your brake linings wear down and you have to
have new ones put in
-- be sure you get new genuine
GM replacement parts. If you don’t, your brakes may no
longer work properly. For example,
if someone puts in
brake linings that are wrong for your vehicle, the balance
between your front and rear brakes can change
-- for the
worse. The braking performance you’ve come
to expect
can change
in many other ways if someone puts in the
wrong replacement brake parts.
