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
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.
ProCarManuals.com

‘ A CAUTICY:
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 vehi.cle’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
50150 mix-of clean
water and
DEX-COOL (orange-colored,
silicate-free) antifreeze.
-
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.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
~~
NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.

nrning the radiator pressure cap when the engine
and radiator are hot can allow steam and scalding
liquids to blow out and burn
you badly. With the
coolant recovery tank, you
will almost never have
to add coolant at the radiator. Never turn the
radiator pressure cap
-- even a little -- when the
engine
and radiator are hot.
Add coolant mix at the recovery tank, but be careful not
to spill it.
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.
Radiator Pressure Cap
NOTICE:
Your radiator pressure cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows
on the cap
line up with the overflow tube on the radiator
filler neck.
When you replace your radiator pressure cap, an
AC@
cap is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system.
The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat
is recommended.

Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use.
If you will be
operating your vehicle in an area where the temperature
may
fall below freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
Open the cap labeled WASHER FLUID ONLY. Add
washer fluid until the tank is
full.

When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
Don’t mix,water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other
parts of the washer system. Also,
water doesn’t clean
as well as washer fluid.
Fill your washer fluid tank only
three-quarters full when
it’s very cold. This
allows for expansion, which could damage
the tank
if it is completely full.
Don’t use radiator antifreeze in your
windshield washer. It can damage your
washer system and paint.

Part C: Periodic Maintenance
Inspections
Listed below are inspections and services which should
be performed at least twice a year (for instance, each
spring and fall). You should let your
GM dealer’s service
department or other qualified service center do these jobs.
Make sure any necessary repairs are completed at once.
Proper procedures to perform these services may be
found in a Buick service manual. See “Service and
Owner Publications” in the Index.
Steering, Suspension and Front-Wheel-Drive
Axle Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear, or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals if necessary.
Exhaust System Inspection
Inspect the complete exhaust system, Inspect the body
near the exhaust system. Look for broken, damaged,
missing or out-of-position parts as well as open seams, holes,
loose connections, or other conditions which
could cause a heat build-up in the floor pan or could let
exhaust fumes into
the vehicle. See “Engine Exhaust” in
the Index.
Radiator and Heater Hose Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed.
Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
and for damage or missing parts. Replace parts as
needed. Replace any cables that have high effort
or
excessive wear. Do not lubricate accelerator and cruise
control cables.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc.
Check parking brake adjustment. You may need to have
your brakes inspected more often if your driving habits
or conditions result in frequent braking.
