1996 CADILLAC DEVILLE radiator cap

Downloaded from www.Manualslib.com manuals search engine NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
A CAUTION:
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.
A
1. You can remove the coolant surge tank pressure
cap when
the cooling system, including the coolant
surge tank pressure cap and upper radiator hose,
is no longer hot.
Turn the pressure cap slowly
counterclockwise until it first stops. (Don't press
down while turning the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there is
still some pressure left.

4. With the coolant surge tank pressure cap off, start the
engine and let it run until
you can feel the upper
radiator hose getting hot. Watch out for the engine
fans.
By this time, the coolant level inside the coolant
surge tank may be lower.
If the level is lower, add
more
of the proper mix to the coolant surge tank
until the level reaches about
2.5 inches (60 mm)
below the base of the filler neck.
5. Then replace the pressure cap. Be sure the arrows on
the pressure cap line up like this.
Start
the engine and allow it to warm up. If the CHECK
COOLANT LEVEL message does not appear on the
Driver Information Center, coolant is at the proper fill
level.
If a CHECK COOLANT LEVEL message does
appear, repeat Steps 1 to
3 or see your dealer.

The oil fill cap is located
behind the radiator
on the
L
~ passenger’s side of the
~ engine. Turn the cap
1 counterclockwise to
remove.
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.
What Kind of Oil to Use
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:

Downloaded from www.Manualslib.com manuals search engine Wait at least 30 minutes before checking the transaxle
fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180°F to 200°F
(82°C to 93°C).
Get the vehicle warmed up by driving abut 15 miles (24 km)
when outside temperatures are above 50°F (10°C). If it's
colder
than 50°F (lO"C), you may have to drive longer.

Park your vehicle on a level place. Keep the engine
running.
With the parking brake applied, place the shift Lever
in
PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position the shift lever
in PARK (P).
Let the engine run at idle for three to five minutes. Then, without shutting off
the engine, follow these steps:
1. The black transaxle fluid cap is located next to the
radiator hose and below the air cleaner assembly
on
the driver's side of the engine. Remove the air
cleaner assembly
so you can reach the transaxle fluid
cap. The assembly is attached to the vehicle
by two
fasteners. Simply
lift up on the air cleaner assembly
to remove it. Find the transaxle fluid cap and turn
it
counterclockwise to remove. Pull out the dipstick
and wipe
it with a clean rag or paper towel.
then pull it back out again.
2. Push it back in all the way, wait three seconds and

.
The surge tank is located next to the engine block on the
passenger’s side of the engine.
The cooling system when hot is under a lot of pressure.
If the CHECK COOLANT LEVEL message appears on
the
DIC, you will’need to add coolant.
A CAUTION:
I’urning 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 (60 mm) below
the
base of the fill neck. Use a flashlight as necessary to
see into the tank.

Adding Coolant
If you need more coolant, add the proper mix at the
surge tank, but only when the engine is cool.
I A CAUTION:
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.
~~~ ~ ~~~~~~~
When replacing the pressure cap, make sure it is tight.
Surge Tank Pressure Cap
I NOTICE:
The surge tank cap is a 15 psi (105 kPa)
pressure-type
cap and must be tightly instalfed to
prevent coolant loss and possible engine damage
from overheating. Be sure
the arrows on the
cap line up.
If the surge tank pressure cap needs to be replaced, a
General Motors cap
is recommended.
Thermostat
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.
If your thermostat needs to be replaced, a General
Motors thermostat
is recommended.

Adding Washer Fluid
The windshield washer fluid reservoir is located next to
the air filter on the driver’s side
of the engine.
Open the cap labeled WASHER
FLUID ONLY. Add
washer fluid until the tank
is full.

e
When using concentrated washer fluid,
follow the manufacturer’s instructions
for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause
the solution to freeze
and damage
your washer fluid tank and
other parts of the washer system. Also,
water doesn’t clean
as well as washer fluid.
Fill your washer fluid tank only
314 full
when
it’s very cold. This allows for
expansion, which could damage the tank if
it is completely full.
Don’t use radiator antifreeze in
your
windshield washer. It can damage your
washer system and paint.
