Downloaded from www.Manualslib.com manuals search engine Break·ln Schedule
See the new vehicle break-in instructions in this manual. Also, we
recommended you drive your new vehicle for 500 miles (600 kilometers) before
trailer towing . AI the end of this 500 mile (600 kilometer) break-in period, avoid
speeds over 50 mph (80 km/h) and full throttle starts during the first 500 miles (800 kilometers) of trailer towing.
CAUTIONS:
BRAKES-To help avoid personal injury due 10 poor braking action:
• Trailer brakes of adequate size are required on Irailers more Ihan 450 kilograms (1,000 pounds) loaded weight.
• If you use trailer brakes with this vehicle , follow the installation and balance
instructions of the trailer brake maker.
• Do not tap into the vehicle's brake system tl the trailer brake system uses
more than 0.3 cubic centimeter (0.02 cubic inch) of fluid from the vehitle's
master cylinder. In this case, the vehicle brake fluid capacity will not be enough to operate both the vehicle and trailer brakes under all kinds of
use.
• All brake fluid parts must be able to stand 20 650 kPa (3,000 psi) .. The
brake fluid tap must be made to the master cylinder port supplying fluid to
the rear brakes. Copper tubing is subject to fatigue failure and must not be
used.
• Before going down a steep or long grade, reduce speed. and shiftlhe transmission into a lower gear 10 help control too' long or too often . This
could cause
Ihe brakes 10 overheal and reduce brake ef\ectiveness. .
HITCHES2T6 HeIP'avoid pe,sona/ ,jQiYry.Que 10 sway caused by such things as
crosswinds , big trucks passing or roact roughness, or due to separalion of the
trailer :
• A properly installed and adjusted (1) frame mounted, weight-distributing
hitch and (2) sway control with enough capacity are required for trailers
more than 900 kilograms
(2,000 pounds) loaded weight.
• If your vehicle has air shocks, keep them at a minimum pressure of 70 to 105 kPa (10 to 15 psi) when installing, adjusting or towing with a weight­
distributing hitch.
• Keep the trailer tongue load at 10"10 of the loaded trailer \'feight for dead­
weight hitches, and 12"10 for weight-distribuling hitches. Tongue loads can be adjusted by proper distribution of the load in the trailer. This can be
checked by
weighjng separately the loaded trailer and then the tongue .
• Do not use axle-mounted hitches. They can damage the axle hOuSing, wheel bearings, wheels or lires.
•
When you remove a trailer hitch, be sure to seal any mounting holes in the
bocjy. This will help prevent entry of exhaust fumes, dirt or water. (See
"Engine Exhaust Gas Caution (Carbon Monoxide)" at the beginning of "Starting and Operating," Section 2 of this manual.)

gage needle goes into the warning zone) and your air conditioner is on, turn it
off.
If the "TEMP" light (or gage) comes on while you are stopped in traffic,
shift the transmission to
"N" (Neutral).
If the "TEMP" light doesn't go off (or the gage needle doesn't start to drop)
within a minute or two:
• Pull over to a safe Place ""d stop the vehicle. Set the parking brake and
shift to "P" (Park) 9r, with a manual transmission, shift to Neutral first, then
set the parking brake.
• DON'T TURN OFF THE ENGINE. INCREASE THE ENGINE SPEED until it
sounds like it's going about twice as fast as normal idle speed. Bring the
idle speed back to normal
after two or three minutes.
tfthe "TEMP" light still doesn't 90 off, (or the gage needle doesn't start to
drop),
NOW TURN OFF THE ENGINE and proceed as follows.
•
lift the engine hood. Look at the coolant level in the "see through" coolant
recovery tank. The coolant level. should be at or above the "Full Cold"
mark on the tank. If it looks like the coolant is boiling, wait until it stops
before proceeding. You should not need to remove the radiator cap to
check the coolant
level and. it can be dangerous if the coolant is still hot. See the following Caution.
CAUTION: To help avoid being burned:

broken or off the pulleys an.d that the fan turns when the engine is started,
•
Add coolant to the recovery tahk.
If
the cQolant level in the recovery tank is althe correct lellel arid the "TEMP"

stop coolant from returning to the radiator. In this case, you may have to add
coolant directly to the radiator.
See "Coolant Replacement" under engine
cooling system
in "Service and Maintenance," Section 5 of this manual. Follow
steps 1 and 10. for the correct way to remove the radiator cap and add .coolant
to the radiator.
After the
"TEMP" light is out (or the gage needle is out of the warning zone),
resume driving at a reduced speed. Return to normal driving after about ten
minutes if the light does not come back
on (or the gage needle does not go

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.

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.
