engine overheat BUICK PARK AVENUE 1996 User Guide

I A CAUTION:
r
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.
When the coolant in the coolant recovery tank is at or
above the
FULL COLD mark, start your vehicle.
If the overheat warning continues, there’s one more
thing you can try.
You can add the proper coolant mix
directly to the radiator but be sure the cooling system is
cool before you do it.

If You’re Stuck: In Sand, Mud,
Ice
or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you must use caution.
If you let your tires SI at high speed, they can
explode,
and you or others could be injured. And,
the transaxle or other parts
of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels as little as possible. Don’t
spin the wheels above
35 mph (55 km/h) as shown
on the speedometer.
I NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well as the tires.
If you spin the wheels
too fast while shifting your transaxle back and
forth, you can destroy your transaxle.
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
Rocking your vehicle
to get it out:
First, turn your steering wheel left and right. That will
clear the area around your front wheels. If your vehicle
has traction control, you should turn the system off. (See
“Traction Control System” in the Index.) Then shift
back and forth between REVERSE (R) and a forward
gear, spinning the wheels
as little as possible. Release
the accelerator pedal while
you shift, and press lightly
on the accelerator pedal when the transaxle is in gear. If
that doesn’t get you out after a few tries, you may need
to be towed out. If you do need to be towed out, see
“Towing Your Vehicle” in the Index.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See “Recommended
Fluids and Lubricants” in the Index.
If the fluid level is low, add only enough
of the proper
fluid to bring the level into the cross-hatched area on
the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
It doesn’t take much fluid, generally less than a pint
(0.5 L). Don’t ovel-fill. We recommend you use only
fluid labeled DEXRON@-111, because fluid with that
label is made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON-I11 is
not covered by your new vehicle warranty.
dipstick hole to
bring it to the proper level.
After adding fluid, recheck the fluid level as
described under “How to Check.”
0 When the correct fluid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL
TM (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your
vehicle for
5 years or 100,000 miles (166 000 km),
whichever occurs first.
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:
Give freezing protection down to -34°F (-37°C).
9 Give boiling protection up to 265 OF ( 129 O C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.

‘ 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.
