1996 BUICK PARK AVENUE radiator cap

When you decideit’s safe to lift the hood, here’s what
you’ll see:
An electric fan under the hood can start up even
when the engine is not running and can injure
you. Keep hands, clothing and tools aw~ay from
any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don’t
do anything else until it cools down.

Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and
if you turn the radiator
pressure cap
-- even a little -- they can come out
at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap, is
hot. Wait for the cooling system and
radiator pressure cap to cool if you ever have to
turn the pressure cap.

1. You can remove the radiator pressure cap when the
cooling system, including the radiator pressure cap
and upper radiator hose, is no longer hot. Turn the
pressure cap slowly counterclockwise until it first
stops. (Don’t press down while turning the
pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there
is still some pressure left.
2. Then keep turning the pressure cap, but now push
down as
you turn it. Remove the pressure cap.

6. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine fans.
7. 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.
8. 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.

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.
