Downloaded from www.Manualslib.com manuals search engine An electric fan under the hood can start up even
when the engine
is not running and can injure
you. Keep hands, clothing and tools away from
any underhood electric fan.
If the coolant inside the coolant surge tank is boiling,
don’t do anything else until it cools down.
The coolant level should be at or above
FULL COLD.
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.
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do,
you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
I NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine fans
are running. If the engine
is overheating, both fans should be running. If they
aren’t, your vehicle needs service.

Downloaded from www.Manualslib.com manuals search engine 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 fM coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.

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.

1. You can remove the coolant surge tank pressure cap
when the cooling system, including the coolant surge
tank pressure cap and upper radiator hose,
is no
longer hot. Turn the pressure cap slowly about
one-quarter
of a turn to the left and then stop.
If you hear a hiss, wait for that
to stop. A hiss means
there is still some pressure left.
2. Then keep turning the pressure cap slowly, and
remove
it.

up to FULL COLD.
4. With the coolant surge tank pressure cap off, start the
engine and let it
run until you can feel the upper
radiator hose getting hot. Watch out
for the
engine fans.
By
this time, the coolant level inside the coolant
surge tank may
be lower. If the level is lower, add
more of the proper
mix to the coolant surge tank
until the level reaches FULL COLD.

Downloaded from www.Manualslib.com manuals search engine A 50/50 mixture of water and the proper coolant for
your Chevrolet will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 OF (129 O C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
NOTICE:
When adding coolant, it is important that you use
only
DEX-COOL TM (silicate-free) coolant.
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 TM coolant which
won’t damage aluminum parts.
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 TM coolant.

NOTICE:
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:
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.
The surge tank is located on the passenger's side of the
engine compartment.

Thrning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
Never turn the surge tank pressure cap
-- even a
little -- when the engine and radiator are hot.
When your engine is cold, the coolant level should be at
the
FULL COLD mark.

If the light comes on, it
means you're low on
engine coolant.
Adding Coolant
If you need more coolant, add the proper DEX-COOL"
coolant mixture ut the surge tank, but only when the
engine is cool.
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.
When replacing the pressure cap, make sure it is tight.

NOTICE:
Your pressure cap is an 15 psi (105 kPa)
pressure-type cap and must be tightly installed to
prevent coolant
loss and possible engine damage
from overheating.
When you replace your surge tank pressure cap, a GM
cap is recommended.
Thermostat Power Steering Fluid
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
you replace your thermostat, an AC@ thermostat
is recommended.
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
three-quarters full when it’s very cold. This
allows for expansion if freezing occurs,
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.
Brakes
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
