When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Radiator Pressure Cap
B. Coolant Recovery Tank
C. Engine Fan(s)
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.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
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.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered
by your warranty.
If there seems to be no leak, start the engine again. See
if the fan speed increases when idle speed is doubled by
pushing the accelerator pedal down.
If it doesn’t, your
vehicle needs service. Turn
off the engine.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the FULL COLD mark, add a 5060 mixture of
clean water (preferably distilled) and DEX-COOL’”
(orange-colored, silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant”
in the Index for
more information.)
Adding only plain water to your cooling sy,,,m
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 antifreeze.

nuts,
and take off the
flat tire.
7. Remove any rust or dirt
from the
wheel bolts,
mounting surfaces and
spare wheel.
A CAUTION:
Rust or dirt on the wheel, or on the parts to
which
it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use a cloth
or a paper towel
to do this; but be
sure to use a scraper or wire
brush later,
if you need to, to get all the rust or
dirt off.
I A CAUTION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing
a serious accident.

your vehicle will have
a auxiliary engine fan in addition
to the belt driven fan.
A CAUTION:
If your vehicle has air conditioning, the auxiliary
engine 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
could be burned. Be careful not to drop or spill
things that will burn onto a hot engine.
Before closing the hood, be sure all the filler caps are
on properly.
Then lift the hood to relieve pressure
on the hood prop.
Remove the hood prop from the slot in the hood and
return the prop
to its retainer. Then just let the hood
down and close
it firmly.

If your vehicle has a diesel engine, see “Engine Oil
(Diesel Engine)” in the Diesel Engine Supplement.
It’s
a good idea to check your engine oil every time you
get fuel.
In order to get an accurate reading, the oil must
be warm and the vehicle must be
on level ground.
Turn off the engine and give the
oil a few minutes to drain
back
into the oil pan. If you
don’t, the oil dipstick might
not show the actual level.
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push
it back in all the way. Remove it again,
keeping
the tip down, and check the level.
When to Add Oil
If the oil is at or below the ADD mark, then you’ll need to
add some
oil. But you must use the right kind. This part
explains what kind
of oil to use. For crankcase capacity,
see “Capacities and Specifications”
in the Index.
I NOTICE:
Don’t add too much oil. If’ your engine has so much
oil that the oil level gets above the upper mark that
shows the proper operating range,
your engine
could be damaged.

The engine oil filler cap is located between the air
cleaner and engine oil dipstick.
Just fill
it enough to put the level somewhere in the
proper operating range. Push the dipstick
all the way
back in when you’re through. Oils recommended for your vehicle can be identified
by
looking for the “Starburst” symbol. This symbol
indicates that the
oil has been certified by the American
Petroleum Institute (API).
Do not use any oil which
does not carry this Starburst symbol.
If you change your own oil,
be sure you use oil that has
the Starburst symbol on the
front
of the oil container.
If you have your oil
changed for you, be sure
the
oil put into your engine
is American Petroleum
Institute certified for
gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:
