1998 CADILLAC DEVILLE cooling

Downloaded from www.Manualslib.com manuals search engine Checking Coolant
L
The surge tank is located next to the engine block on the
passenger's side of the engine.
The cooling system is under a lot of pressure when it is
hot.
If the CHECK COOLANT LEVEL message
appears on the Driver Information Center (DIC), you
will need to add coolant.
l'brning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow
out and burn you badly.
Never turn
the surge tank pressure cap -- even a
little
-- when the engine and radiator are hot.
When your engine is cold, the coolant level should be
at the
FULL COLD mark, which is 2.5 inches (6.4 cm)
below the base
of the fill neck. Use a flashlight as
necessary to
see into the tank.

If the CHECK COOLANT LEVEL message comes on,
it means you're low on engine coolant.
For more information, see "Check Coolant Level"
message in the Index.

Replace any wheel that is bent, cracked, or badly rusted
or corroded.
If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced. If the
wheel leaks
air, replace it (except some aluminum
wheels, which can sometimes be’repaired). See your
dealer
if any of these conditions exist.
Your dealer
will know the kind of wheel you need.
Each
new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new
GM original
equipment parts.
This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your Cadillac model.
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous.
It could affect the braking and
handling
of your vehicle, make your tires lose
air and make you lose control. You could have a
collision in which you or others
could be injured.
Always use the correct wheel, wheel bolts and
wheel nuts
for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer
or
-odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
See “Changing a Flat Tire” in the Index for
more information.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band
is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one
of the identical size
and rating.
If you ever have a problem on the road and don’t
have a spare fuse, you can “borrow” one that has the same amperage. Pick some feature
of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
There are two fuse blocks in your vehicle: the engine
compartment fuse block and the rear compartment
fuse block.
