1998 CADILLAC DEVILLE coolant level

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the proper level
(2.5 inches (6.4 cm) below the
base of the fill neck), add a
50/50 mixture of clean
water (preferably distilled) and DEX-COOL’ coolant at
the coolant surge tank, but be sure the cooling system,
including the coolant surge tank pressure cap, is cool
before
you do it. (See “Engine Coolant” in the Index for
more information.)
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the coolant
surge tank pressure cap
-- even a little -- they
can come out
at high speed. Never turn the
cap when the cooling system, including the
coolant surge tank pressure cap,
is hot. Wait
for the cooling system and coolant surge tank
pressure cap to cool
if you ever have to turn
the pressure cap. Adding
only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system
is set for the proper coolant
mixture. With plain water or the wrong mixture,
your engine could get too hot but you wouldn’t

engine and let it run until
you can feel the upper
radiator hose getting hot. Watch out for the engine
cooling 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 mixture to the coolant surge tank
until the level reaches about
2.5 inches (6.4 cm)
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 through 3 or see your dealer.

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.

Downloaded from www.Manualslib.com manuals search engine Power Steering Fluid
The power steering fluid
reservoir is located next to
the coolant surge.tank on
the passenger’s side of
the engine.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap
and the top
of the reservoir clean, then unscrew the cap
and wipe the dipstick with a clean rag. Replace the cap
and completely tighten it. Then remove the cap again
and look at the fluid level on the dipstick.
The level should be at the
FULL COLD mark. If
necessary, add only enough fluid to bring the level up
to the mark.
What to Use
To determine what kind of fluid to use, see
“Recommended Fluids and Lubricants” in the
Maintenance Schedule booklet. Always use the
proper fluid. Failure to use the proper fluid can cause
leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use.
If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
