COLD when the engine is cold.
Ifa Tire Goes Flat
It’s unusual for a tire to (‘blow out’’
while you’re driving, especially if you
maintain your tires properly. If air goes
out
of a tire, it’s much more likely to
leak out slowly. But
if you should ever
have a “blowout,” here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire will
create a drag that pulls the vehicle
toward that side. Take your foot
off the
accelerator pedal and
grip the steering
wheel firmly. Steer to maintain lane
position, then gently brake to a stop
well out of the trafEic lane.
A rear blowout, particularly on a curve,
acts much like a skid and may require
the same correction you’d use in a skid.
In any rear blowout, remove your foot
from the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It may
be very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road if possible.
If your tire goes flat, the
next section
shows how to use your jacking
equipment to change a flat tire safely.

Then go to the front of the vehicle and
release the secondary hood release.
Lift the hood. An electric fan
under the
hood can start up and injure
you even when the engine is not
running. Keep hands, clothing and
tools away from any underhood
electric fan.

Things that burn can get on
hot engine parts and start a
fire. These include liquids like gasoline,
oil, coolant, brake fluid,
windshield washer and other fluids,
and plastic or rubber.
You or others
nnuld be burned. Be careful not to
-,3p or spill things that will burn
onto
a hot enqine.

Adding Coolant
To Check Coolant:
When your engine is cold, the coolant
level should be between
the COLD
and HOT marks or a little higher.
When your
engine is warm, the level
should be u.p to HOT, or a little
higher.
If this light comes on, it means you’re
low
on engine coolant.
To Add Coolant:
If you need more coolant, add the
proper
mix at the coolant recovery
tank.
Turning the radiator pressure I
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
radia
I are hot.

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.

Cooling System Service*-Drain, flush, and refill
the system with new or approved recycled coolant
conforming to
GM Specification 1825M. Keep
coolant at the proper mixture as specified. See the
Index under Coolant. This provides proper freeze
protection, corrosion inhibitor level, and engine
operating temperature.
Inspect hoses and replace if they are cracked,
swollen or deteriorated. Tighten screw-type hose
clamps. Clean the outside of the radiator and air
conditioning condenser. Wash the pressure cap
and neck.
To help ensure proper operation, we recommend a
pressure test of both the cooling system and the
pressure cap.
