1. You can remove the radiator pressure cap when the cooling system,
including the radiator pressure cap and upper radiator hose, is
no
longer hot. Turn the pressure cap slowly to the left 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.

5. Put the cap back
on the coolant
recovery tank, but
leave the radiator
pressure cap
off.
6. Start the engine
and let it run
until
you can feel the
upper radiator
hose getting hot.
Watch out for the
engine fans.
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 filler neck.

An electric 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.

A CAUTION:
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 just pull the
hood down until it’s about 15 inches (38 cm) from
closing. Then close it firmly.
FLUID USAGE LABEL
Use the fluid usage label to identify the correct fluid you want to check.

The following explains your cooling system and how to add coolant when
it is
low. If you have a problem with engine overheating, see “Engine
Overheating” in the Index.
The proper coolant for your Cadillac will:
0 Give freezing protection down to -34°F (-37°C) .
0 Give boiling protection up to 262°F (128” C) .
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights work as they should.
What to Use:
Use a mixture
of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 1825-M,” which won’t damage
aluminum parts.
You can also use a recycled coolant conforming to GM
Specification 1825-M with a complete coolant flush and refill. Use GM
Engine Coolant Supplement (sealer) with any complete coolant change.
If you use these, you don’t need to add anything else.
A CAUTION:
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 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
Waf--- and
a proper anti” e. .-

To Check Coolant:
When your engine
is
cold, the coolant level
should be at “FULL
COLD,” or a little
higher. When your
engine is
warm, the
level should be
up to
“FULL
HOT,” or a
little higher.
To Add Coolant: If you need more coolant, add the proper mix at the
coolant recovery tank.
A CAUTION: I
lhrning the radiator pressure cap when the engine and radiator si:;
-z. *?’
are hot can allow steam and scalding liquids to blow out and
burn you badly. With the coolant recovery tank, you will almost
never have to add coolant at the radiator. Never turn the
radiator pressure cap
-- even q little -- when tken le and
radiator are hot.

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 enougl- spill coolant on
a hot e-yine.
RADUTOR PRESSURE CAP
I-
_I
must be tightly Installed to prevent coolant loss and possible
engine
damage from overheating. Be sure the arrows on the c
line up with the overflow tube on the radiator filler neck .L
When you replace your radiator pressure cap, an ACS 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.
When you replace your thermostat, an
AC@ thermostat is recommended.
