up than the gage indicated. For
example, the gage may have indicated
the tank was half full, but it actually
took
a little more or less than half the
tank’s capacity to fill the tank.
The gage moves a little when you turn
a corner or speed up.
The gage doesn’t go back to E when
you turn off the ignition.
For your fuel tank capacity, see

If the gage pointer moves into the red
area, your engine is too hot! It means
that
your engine coolant has
overheated.
If you have been operating
your vehicle under normal driving
conditions, you should pull
off the road,
stop your vehicle and turn
off the
engine as soon as possible.

NOTICE:
Towing a vehicle over rough
surfaces could damage a vehicle.
Damage can occur from vehicle to
ground or vehicle to wheel-lift
equipment. To help avoid damage,
install a towing dolly and raise
vehicle until adequate clearance is
obtained between the ground
and/or wheel-lift equipment.
Do not attach winch cables or J-hooks
to suspension components when
using car carrier equipment. Always
use T-hooks inserted in the T-hook

I Hydraulic Clutch
The hydraulic clutch
in your vehicle is
self-adjusting. The clutch master
cylinder reservoir is filled with hydraulic
clutch fluid.
It isn’t
a good idea to “top off” your
clutch fluid. Adding fluid won’t correct
a leak.
A fluid loss in this system could
indicate a problem. Have the system
inspected and repaired.
When to Check and What to Use
Refer to the Maintenance Schedule to
determine how often
you should check
the fluid level in your clutch master
cylinder reservoir and for the proper fluid. See
Owner Checks and
Services
and Recommended Fluids and
Lubricants
in the Index.
How to Check
You do not need to check the fluid level
unless you suspect a clutch problem.
To
check the fluid level, take the cap off. If
the fluid reaches the step inside the
reservoir, the fluid level is correct.
I Engine Coolunt
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 Chevrolet will:
Give freezing protection down to -34°F
Give boiling protection up to 262°F
Protect against rust and corrosion.

should.
What to Use
Use a mixture
of one-half clean water
(preferably distilled) and one-half
antifreeze that meets “GM Specification
1825-M,” which won’t damage aluminum
parts. You can also use a recycled
coolant conforming to GM Specification
1825-M with
a complete coolant flush
and refill. If you use this mixture, you
don’t need to add anything else.

Adding Coolant -3. IL V6 Engine
To Check Coolant
When your engine is cold, the coolant
level should be at
FULL COLD, or a
little
higher.
To Add Coolant
If you need more coolant, add the
proper
mix at the surge tank.

Radiator Pressure Cap
NOTICE:
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.
When
you replace your radiator
pressure cap, a
GM cap is recommended.
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
you replace your thermostat, an
AC@ thermostat is recommended.
