1996 BUICK CENTURY radiator

8. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine fan.
9. By this time the coolant level inside the radiator
filler neck may be lower.
If the level is lower, add
more
of the proper mix through the filler neck until
the level reaches the base of the filler neck. 10.
Then replace the
pressure cap. At any
time during this
procedure
if coolant
begins to
flow out of
the filler neck, reinstall
the pressure cap. Be
sure the arrows on
the
pressure cap line up
like this.
11. Check the coolant
in the recovery tank. The level in
the coolant recovery tank should be at the HOT
mark when the engine is hot or at the COLD mark
when
the engine is cold.

Engine Coolant
@ Protect ag- rust and corrosion.
@ Help.keep the proper engine temperature.
Let the whg lightd md gages work as
they shouicl.
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 engiue
coolant will
require change sooner -- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.
ProCarManuals.com

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.
lain 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
water and
DEX-COOL TM (orange-colored,
silicate-free) antifreeze.
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.
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.

rhacking Coc’mt * clding Coolant
!
The coolant recovery tank is located on the passenger’s
side
of the engine compartment.
When your engine is cold, the coolant level should be at
ADD or a little higher. When your engine is warm, the
level should be up to
FULL HOT or a little higher.
.
If you need more coolant, add the proper mix at the
coolant recovery tank.
If the coolant recovery tank is completely empty, add
coolant to the radiator. (See “Engine Overheating”
in the Index.)
I-
Thrning 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.
ProCarManuals.com

Add coolant mix at the recovery tank, but be careful not
to spill it.
'B CAUTION:
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 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.

Adc J Washer 1
The windshield washer reservoir is located on the

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.
