Do not tow with sling-type
equipment or hcia/fog light damage
will occur. Use wheel-lift or car
carrier equipment (additional
ramping may be required for car
carrier equipment). Use safety
chains and wheel straps.
To help avoid damaging a vehicle
during a tow over rough surfaces,
install a towing dolly beneath the
wheels that would otherwise be on
the ground during the tow. This
will increase clearance between the wheel-lift equipment and the
underbody
of the towed vehicle.

If you get the overheat warning but see

be too serious. Sometimes the engine
can get a little too hot when you:

Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer. If you
get the overheat warning with no
sign of steam, try this for a minute or
so:
1 . Turn off your air conditioner.
2. Turn your heater to full hot at the

Engine Overheating (CONK)
Cooling System
When you decide it’s safe to
lift the
hood, here’s what you’ll see:
(A) Coolant recovery tank
(B) Radiator pressure cap
(C) Electric engine fan
An
electric fan under the hood
h 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
recovery tank is boiling, don’t do
anything else
until it cools down.
The coolant level should be at or above
the
FULL COLD mark. 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.
I I 1 Heater and radiator hoses, anc
- 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.

engine without coolant isn’t

If you haven’t found a problem yet, but
the coolant level isn’t up to the

clean water (preferably distilled) and a
proper antifreeze at the coolant recovery
tank. See the Index under Coolant for

6. Start the engine and let it run until
you can feel the upper radiator hose
getting hot. Watch out for the engine

7. By this time, the coolant level inside
the radiator filler neck may be lower.
If the level is lower, add more of the
proper mix through the filler neck
until the level reaches the base of the

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 1
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 traffic lane.
ProCarManuals.com

Page 210 of 322

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.
Air lnflator Sysfem
Some vehicles have an air inflator for
use in bringing tires up to the proper
pressure. The air inflator is located in
the trunk. The
ON switch will work
even with the ignition off. The air
inflator comes with
a kit that
includes a 20-foot hose and an air
pressure gage, as well as instructions
and special adapters for inflating things
like an air mattress or basketball.
Inflating something too much
can make it explode, and
you
or others could be injured. Be sure
to read the inflator instructions,
and inflate any object only
to its
1 recommended pressure.
