1998 CADILLAC ELDORADO overheating

Downloaded from www.Manualslib.com manuals search engine Engine Coolant
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.
J
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).
Give boiling protection up to 265 “F (1 29°C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 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
-0 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.

If you need more coolant, add the proper DEX-COOL@
coolant mixture ut 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
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
GM 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 GM
thermostat is recommended.

A CAUTION:
~~ ~~
Poorly maintained and improperly used tires
are dangerous.

Overloading your tires can cause overheating
as a result of too much friction. You could have
an air-out and a serious accident. See “Loading
Your Vehicle”
h the Index.
UnderinfJated 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.
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.
CAUTION: (Continued) CAUTION: (Continued)
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.
Inflation -- Tire Pressure
The Tire-Loading Information label, which is located
on the rear edge of the driver’s door, shows the correct
inflation pressures for your tires when they’re cold.
“Cold” means your vehicle has been sitting for at least
three hours or driven
no more than 1 mile (1.6 km).
If you’ll be driving at speeds higher than 100 mph
(160 km/h) where it is legal, raise the cold inflation
pressure of each tire to
35 psi (240 kPa). When you end
this very high-speed driving, reduce the cold inflation
pressures
to those listed on the Tire-Loading
Information label.
