warning light CADILLAC DEVILLE 1993 7.G Owner's Manual

YOU will find the two warning lights about a hot engine on your Cadillac
instrument panel.
If Steam Is Coming From Your Engine:
A CAUTION:
Steam from an overheated engine can burn you badly, even if
you just open the hood. Stay
away from the engine if you see or
hear steam coming from it. Just turn it
off and get everyone
away from the vehicle until it cools down. Wait until there is no
sign
of steam or coolant before opening the hood.
If you keep driving when your engine is overheated, the liquids
in it can catch fire. You or others could be badly burned. Stop
your engine if it overheats, and get out
of the vehicle until the I

l-
engine is cool.

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. .-

leaking out
of the brake system. If it is, you should have your brake
system fixed, since a leak means that sooner
or later your brakes won’t
work well, or won’t work at all.
So, it isn’t a good idea to “top off” your
brake fluid. Adding brake fluid won’t correct a leak.
If you add fluid when
your linings are worn, then you’ll have too much fluid when you get new
brake linings.
You should add (or remove) brake fluid, as necessary, only
when work is done on the brake hydraulic system.

I only when work is done on the brake hydraulic system.
If you have too much brake fluid, it can spill on the engine. The
fluid will burn if the engine is hot enough. You or others could
be burned, and your vehicle could be damaged. Add brake fluid
U
When your brake fluid falls to a low level, your brake warning light will
come on. See “Brake System Warning Light” in the Index.
To Check Brake Fluid:
You can check the brake fluid without taking off the cap. If it’s low, fill it
to the maximum “FLUID LEVEC’ indicator.

The headlight wiring is protected by a circuit breaker in the light switch.
An electrical overload
will cause the lights to go on and off, or in some
cases to remain off.
If this happens, have your headlight wiring checked
right away.
Windshield Wipers
r
The windshield wiper motor is protected by a circuit breaker and a fuse.
If the motor overheats due to heavy snow, etc., the wiper will stop until
the motor cools. If the overload is caused by some electrical problem and
not snow, etc.,
be sure to get it fixed.
I_
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows and other
power accessories. When the current load is too heavy, the circuit breaker
-
opens and closes, protecting the circuit until the problem is fixed or goes
away.
