A’
Adding Coolant
To Check Coolant:
When your engine is cold, the coolant
level should be between the
FULL
COLD mark and FULL HOT. When
your engine is warm, the level should be
up
to FULL HOT, or a little higher.
m.. 240
If you have the optional low coolant
warning light and it comes on when
your engine is running, you’re low on
coolant. Or, if you have the optional
Driver Information Center and the
warning
LOW COOLANT appears,
you’re low on coolant.
To Add Coolant:
If you need more coolant, add the
proper
mix at the coolant recovery
tank.
II Turning the radiator pressure 1
- 1 cap when the engine and
raalator are hot can allow steam
and scalding liquids to blow out
and bum
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.
ProCarManuals.com

Add coolant mix at the recovery tank,
but be careful not to spill it.
I "-" ""IW
You can be burned if you spill
L 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. I
Radiator Pressure Cap I Thermostat
1,. Your radiator pressure cap is a 15 psi (105 kPa) pressure-type cap and
must be tightly installed
to prevent
coolant
loss and possible engine i.
damage from overheating. Be sure
the arrows on the cap line up with
the overflow tube on the radiator
..
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 you replace your radiator pressure
cap, an AC@ cap is recommended.

Brake Master Cylinder (CONI:)
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.
, If you have too much brake
hid,
it can spill on the
engine. The fluid will burn if the
engine is hot enough.
You or
others could be burned, and your
engine could be damaged. Add
brake fluid only when work is
done on the brake hydraulic
system.
244
When your brake fluid falls to a low
level, your brake warning light will
come on. A continuous chime will
sound if
you try to drive with this
warning light on. See the
Index under
Brake System Warning Light.
What to Add:
When you do need brake fluid, use only
DOT-3 brake fluid-such as Delco
Supreme
ll@ (GM Part No. 1052535).
Use new brake fluid from a sealed
container only.
DOT-5 silicone brake fluid can
damage your vehicle. Don’t use
it.
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.

engine code for your
GM engine. This
code will help you identify your engine,
specifications, and replacement parts in
