CATALYTIC CONVERTER
.Ttle .cal;!ly:tic converter is an emission control device added to the exhaust system,' to reduce exhaust gas pollutants. The converter contains
a ceramic material coated with noble metal catalysts. To prevent contamination
of the catalysts , unleaded gasol;"" must be used . Unleaded gasoline also
reduces spark plug louling. exhaust system corrosion and engine oil
deterioration.
The catalytiC converter requires the use of unleaded gasoline. Using leaded gasoline wilt cause --the converter to lose its effectiveness as an
emission control device. Leaded gasoline will also damage the Computer
Command Control, system oxygen sensor, which could affect emission control,
fuel economy . and drivability.
~,~.,y..'~,","~ ... :..., To help 'prevent damage:
1. Keep your engine properly maintained . Engine malfunctions involving the electrical, carburetion or ignition systems may result in unusually high
catalytic con verter and exhaust . sy~tem temperatures which, under
extreme malfunctioning conditions·, may ignite interior floor:"'covering
materials above the converter. Do not keep driving your vehicle if you
detect engine misfire, noticeable loss of performance ,or other unusual operating conditions. Instead. have it serviced promptly.
A properly maintained
engine will help avoid malfunctions that could damage
the converter.
~ will also help provide good emission control and fuel economy.
See the Maintenance Schedule , folder for information on inspecling and
maintaining the engine. exhaust system. and other components. .
2. Do not drive through or Idle or park your vehicle over combustible
materials, such as grass or leaves_ They could touch the hot exhaust
system and ignite.
3. Do not push or tow this vehiCle to start it. This may result in unusually
high catalytic converter and exhaust system temperatures which under
extreme conditions may ignite interior floor -covering material above the
converter.
Pushing or towing to start can also damage · the catalytic
converter itself.

WARM
Add just enough DEXRO~ II fluid to fill the transmission to the proper level. It
takes only 0.5 liter (one pint) to raise the level from "Add" to "Full" with a hot
transmission.
Automatic Transmission Drain Intervals
Change the transmission fluid and change the filter (or clean the screen) as
outlined
in Section A of the Maintenance Schedule folder.
ENGINE COOLING SYSTEM
Your vehicle has a coolant recovery system. Coolant in the system expands
with heat and overflows into the recovery tank. When the system cools down,
coolant is drawn back into the radiator.
The cooling system was
filled at the factory wrth a quality coolant that meets
GM
Spec~ication 1S99-M . The cooling ·system is designed to use coolant (a
mixture of water and ethylene glycol antifreeze) rather than plain water. The
coolant solution should be used year round.
It has many advantages, such as:
~ provides freezing protection down to -3rC (-34"F) "''''''<~. !'"","."" ' • provides boiling protection up to 12S"C (262"F),
• protects against rust and corrosio~in th~ cooling system,
• maintains the proper engine temperature for efficient operation and
emission control, and
• allows proper operation of the coolant temperature light or gage :
See Section A of the Maintenance Schedule folder to find out when the coolant
must
be ·replaced.
Cooling System Care
Check the c60ling system at regular intervals, such as during fuel stops . You usually do not need to remove the radiator cap to check the coolant level. Lift
the engine hood and look at the "see through" coolant recovery tank. When
the engine is
cold, the coolant level should be at the "Full Cold" mark on the
tank . When the engine has fully warmed . up, the level should be above the
"Full Cold" mark on the tank . If the coolantl6vel is low, remove the cap on the
coolant recovery tank. Add to the recovery tank enough of a 50/50 mixture of
water and a good quality ethylene glycol antifreeze to bring the
level up to the
proper mark. Put the cap back on the recovery tank.
Certain conditions, such
as air trapped in the system, may affect the coolant
level in the radiator. You should check"the coolant level in the radiator at the
time you change the engine
oil and when the engine Is cold. Follow.taps I, S,
9, and 10 under "Coolant Repfacement" for the correct way to remove the
radiator cap and add coolant.

Downloaded from www.Manualslib.com manuals search engine If you have to add coolant more than four times a year (either to the recovery
tank or to the radiator), see your dealer for a cooling system check.
NOTICE: If you use the proper quality antifreeze, there is no· need to add extra inhihitorsor additiveswtlich claim to improve-the system. They may be harmful to the proper operation of the system.
Cooling' System Service
The cooling system should be serviced at the intervals specified in Section A of
the Maintenance Schedule folder as follows:
1. Wash the radiator cap and filler neck with clean water. See step 1 of "Coolant Replacement" for the proper way to remove the radiator cap.
2. Check the coolant level in the radiator and have it tested for freeze
protection.
Add ethylene glycol antifreeze, if needed, to maintain freeze
protection at-3JOC (~$4°f).
3. Have the cooling system and radiator cap tested for a pressure capacity of 105. kPa (15psi). (The pressure cantle anywhere from 95 kPa, or 14 psi,
to 120
kPa, or 18 psi.) If a replacement cap is needed, use an AC cap, or
an equivalent cap, designed fof coolant recovery systems and specffied for
your model.
4. Tighten all radiator hose clamps ang heater hose clamps and inspect all
hoses. Replace the hOSes if they are swollen, "checked" or otherwise worn.
NOTICE: Take care when tightening the hose clamps at the radiator. Overtightening could bend or collapse the radiator fittings.
5. Clean the front of the radiator core and air conditioning condenser to
remove dirt and other objects. Also clean the auxiliary engine oil andlor
transmission fluid cooler if the vehicle has them.
Coolant Replacernent
At the intervals specffied in Section A of the Maintenance Schedule folder, flush
9r1d refill the cooling system as follows:
1. Remove the radiator cap when the engine is cool:
•
Turn the cap slowly to the left until it reaches a "stop." Do not press
down while turning the
cap.
• Wait until any remaining pressure (indicated by a hissing sound) is
relieved, then press down on the cap and continue turning it to the left.
CAUTION: To help avoid the dangarm being burned. donotrem_ove the radiator cap While the engine' and radiator are. still. hot. Scaldingftukland steam ean be blown out under ~re It the cap is taken off too SOOf1.
2. When the cap is removed, run the engine until the upper rad.iator hose is
hot.
(ThiS shows that th~ thermostat is open and the coolant is flowing
through the system.)
3. Stop the engine. Open Ihe,actialor drain valVE! to drain the coolant. Drainage may be speeded by removing the drain plugs in the block, ff so
equipped.

5. Be sure to put the tire inflation valve caps back on, if so equipped. This
will help keep dirt · and moisture from getting into the valve core which
could cause a leak.
6. If an air loss occurs while driving, do not drive on the flat tire more than is
needed to stop safely. Driving even a short distance
ona flat tire can
damage a tire and wheel beyond repair.
Inspection and Rotation
Front and rear tires perlorm different jobs and can wear differently depending
on the types of roads driven , your driving habits, etc .
For longer tire
life, you should inspect and rotate your tires as recommended in
Section A of the Maintenance Schedule folder. Many car and tire dealers will perform a free tire inspection to look for uneven or abnormal tire wear (usually
caused
by wrong inflation pressures, lack of regular rotation, improper wheel
alignment, out
of balance tires, or poor driving habits).
After rotation , adjust the front
and. rear tire pressures (see the Tire Placard)
and be sure to check wheel nut tightness . (Wheel nuts should also be
tightened at certain intervals; see the Wheel Nut Torque Caution in "In Case of
Emergency" section,
page 3·7, for further information.)
