The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant
is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX-COOL" extended
life coolant.
8
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.
A 50/50 mixture of water and DEX-COOL"
coolant will:
0 Give freezing protection down to -34°F (-37°C).
c
F
Give boiling protection up to 265°F (129°C).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
NOTICE:
When adding coolant, it is important that you
use only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@' is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the use
of coolant other than DEX-COOL@ is not
covered
by your new vehicle warranty.
Use a mixture of one-half cEean wccfer (preferably
distilled) and one-half DEX-COOL'" coolant which
won't damage aluminum parts.
If you use this mixture,
you don't need to add anything else.

If you need
more coolant, add the proper DEX-COOL@
coolant mixture 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.
I NOTICE:
~~~~~~~~~~ ~
The surge tank cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed
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.
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.

Your new Cadillac comes with high-quality tires made
by a leading tire manufacturer.
If you ever have
questions about your tire warranty and where
to obtain
service, see your Cadillac Warranty booklet
for details.
A CAUTION:
Poorly maintained and improperly used tires are
dangerous.
0 Overloading your tires can cause overheating
as a
result of too much friction. You could
have
an airout and a serious accident. See
‘Zoading Your Vehicle”
in the Index.
0 Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
CAUTION: (Continued)
CAUTION: (Continued)
0 Overinflated tires are more likely to be
cut, punctured
or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
0 Worn, old tires can cause accidents. If your
tread
is badly worn, or if your tires have
been damaged, replace them.
See “Inflation
-- Tire Pressure” in this section
for inflation pressure adjustment for higher
speed driving.
