Engine Oil Additives
There are many extra engine oil additives (or helpers) for sale. Your engine
should not need these extra additives if you Use SF-quality engine oil and
change it as suggested. If you think your engine has an oil-related problem,
talk
to your authorized dealer. If needed, your dealer can provide you with a
tested and approved oil additive called "GM Engine Oil Supplement."
AUTOMATIC TRANSMISSION FLUID RECOMMENDATIONS
Proper Fluid -Use only automatic transmission fluid labeled DEXRON® II. You
can buy this fluid from your dealer or other service outlets.
Checking
Fluid Level-Check the automatic transmission fluid level at each
engine
oil change, Overfilling GaI).c"!,J~e foaming and loss of fluid. A low fluid
level can cause slipping or loss of drive. In either case, transmission damage
can result.
To check the fluid
level, first set the parking brake, then start the engine in "P"(Park). With the regular brakes applied, move the shift lever through all the
gear ranges, ending
in "P". You must check the fluid level with the engine
running
at slow idle and the vehicle level.
You cannot read the correct fluid level if you have just.driven you(vehicle fora
long time at high speed, in city traffic in hot weather, or if your vehicle has
been
pulling a trailer. Wait until the fluid cools down (about 30 minutes).
Remove the dipstick
located at the rear of the engine compartment on the
passenger's side. Carefully touch the wet end of the dipstick to find out if the
fluid
is cool, warm or hot. Wipe it clean and push it back in until the cap seats. Pull out the dipstick and read the fluid level.
• If
it felt cool (about room temperature), the level should be 3 to 10
millimeters (118 to 3/8 inch) below the "Add" mark. The dipstick has two
dimples below the" Add" mark to show this range.
• If it felt warm, the level should be close to \he "Add" mark (either above or below).
• If
it was too hot to hold, the level should be at the "Full" mark.

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.
5-6

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.
5-7

Downloaded from www.Manualslib.com manuals search engine 4. Close the drain valve. Install the block drain plugs, if removed. Add water
until the system is
filled and run the engine until the upper radiator hose is
hot
again.
5. Repeat steps 3 and 4 several times until the drained liquid is nearly colorless.
6. Drain the system, then close the radiator drain valve tightly. Install block
drain plugs, if removed.
7. Disconnect all hoses from the coolant recovery tank. Remove the recovery
tank
and pour out any fluid. Scrub and clean the inside of the recovery
tank with soap and water. Flush it well with clean water, then drain it.
Reinstall the recovery tank and hoses.
8. Add enough water and ethylene glycol antifreeze (meeting GM
Specification 1899-M) to provide the required cooling, freezing and
c()rrosion protection, Use a solution that is at least 50 percent antifreeze out no mOre than 70 percent antifreeze. Fill the radiator to the base of the
filler neck
and fill the coolant recovery tank to the "Full Hot" mark. Put the
recovery tank cap back on.
9. Run the engine, with the radiator cap removed, until the upper radiator
hose is hot.
10. With the engine idling, add coolant to the radiator until it reaches the
bottom of the filler neck. Install the radiator cap, making sure the arrows on the cap line up with the overflow tube.
iI is the owner's responsibility to,
'. -Main)!!!n cooling system freeze protection at -3rC (-34'F) to ensure protection against corrosion and loss of coolant from boiling. (A 50/50
mixture of water and ethylene glycol antifreeze will provide freeze
protection to -37'C or -34'F.) You should do this even if you don't
expect freezing temperatures.
• Add ethylene glycol base' antifreeze that meets GM Specification 1899-M
when antifreeze haS to be added because of coolant loss or for more
protection against freezing at temperatures lower than -37'C (-34'F).
NOTICE: Do "otute methanol-base antifreeze, Of alcohol,or plain water alone, in your vehicle at any time. They will boil at a lower point than that at which the "TEMP"
light (or temperature gage) will warn of overheating,. and they do not provide proper protection against cOrrosion.
Radiator Pressure Cap
The radiator cap, a 105 kPa (15 psi) pressure type, must be installed tightly,
otherwise coolant may be lost and damage to engine may result from
overheating. Radiator pressure
caps should be checked periodically for proper
operation. If replacement is required, an AC cap is recommended.
Thermostat
The engine coolant temperature is controlled by a thermostat. It stops coolant
flow
through the radiator until a preset temperature is reached. This thermostat
is installed in the engine
coolant outlet on the engine block. The same thermostat is used in both winter and summer. When a replacement is needed, AC"Delco parts are recommended.
