Cadillac 1996 DeVille User Manual

Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your
vehicle for
5 years or 100,000 miles (166 0o0 km),
whichever occurs first.
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 the proper coolant for
your Cadillac will:
Give freezing protection down to -34°F (-37 O C).
Give boiling protection up to 265 “F (129 “C).
Protect against rust and corrosion.
0 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
DEX-COOL TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant 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.
What
to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL (orange-colored,
silicate-free) antifreeze that meets
GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need
to add anything else.
A special procedure is required for adding sealer; see the
Cadillac service manual.
(To order a service manual, see
