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 (1 66 000 km)?
whichever occurs fiist.
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 Buick will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265,”F (129°C).
0 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
DEX-COOL (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 kin) or 24 months
whichever occurs first.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half DEX-COOL
TM (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.
