1993 CADILLAC DEVILLE cooling

Downloaded from www.Manualslib.com manuals search engine 0
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 radiator pressure'cap
-- even a little -- they can come
out at high speed. Never turn the cap when the cooling system,
including the radiator pressure cap,
is hot. Wait for the cooling
system
and radiator pressure cap to cool if you ever have to turn
the pressure cap.

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.

2. Then keep turning
the pressure cap,
but
now push
down
as you turn
it. Remove the
pressure cap.

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. .-
