How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at or above the
“FULL COLD” mark, add a 50/50
mixture of clean water (preferably distilled) and a
proper antifreeze at the coolant recovery tank. (See
“Engine Coolant’’
in the Index for more information
about the proper coolant mix.)
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts. Use
the recommended coolant.

Engine Oil Additives
Don’t add anything to your oil. Your Buick dealer is
ready to advise if you think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 4 miles (6 km).
It’s below freezing outside and most trips are less
than
10 miles (16 km).
The engine is at low speed most of the time (as in
door-to-door delivery, or in stop-and-go traffic).
0 You tow a trailer often.
Most trips are through dusty places.
If any one of these is true for your vehicle, then you
need to change your oil and filter every
3,000 miles
(5 000 km) or 3 months -- whichever comes first. (See
“Change Oil Soon” in the Index.) If
none of
them is true, change the oil every 7,500 miles
(12 500 km) or 12 months -- whichever comes first.
Change the filter at the first oil change and at every
other oil change after that.
If the optional “Change Oil Soon” light comes on you
will need to change your oil sooner than either mileage
specified. Depending upon driving habits, the “Change
Oil Soon’’ light may come on
as early as 2,000 miles or
less from the last time the oil life monitor was reset (See
“Oil Life Monitor” in the Index.)
Always reset the oil
life monitor after every oil change.
Engine Coolant Heater (Engine Block
Heater)
An engine coolant heater can be a big help if you have
to park outside in very cold weather,
0°F (- 18 “C) or
colder. If your vehicle has this option, see “Engine
Coolant Heater” in the Index.

Engine Coolant
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 Buick 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.
0 Help keep the proper engine temperature,
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. If you use this mixture,
you don’t need to add
anything else.
I NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by your
warranty. Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
