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 When replacing tires with those not having a TPC Spec. No., you should use
the same size,
load range, and constructiontype (bias, bias-bened, or radial)
as the original tires on your
vehicle . Although ~ is not generaly recommended ,
some alpha-size and metric-size tires can be interchanged. (For size
equivalency, contact your Chevrolet
dealer or a tire dealer) . A different size or
type of tire may affect ride,
handling, speedometer /odometer calibration,
vehicle ground clearance , and tire or tire chain clearance to the body or
chassis .
II replacing only a single tire, it should be paired on the same axle with the least worn tire of the other three.
UNIFORM TIRE QUALITY GRADING
The following information relates to the tire grading system developed by the
National Highway Traffic Safety' Adminlslration which will grade tires by
treadwear, traction and temperature performance.
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire
when tested under
controlled conditions on a specified government test
course . For example, the tire graded 150 would wear one and a haij (1-1/2)
times as well on the government course as a tire graded 100. The relative
performance of tires depends upon the. actual conditions of their _ use , however ,
and may depart significanlly from the norm due to variations in driving habits , service practices and. differences in road characteristics and climate.
TRACTION -A, B,C
. T~~tr~ction grades, from highest to lowest are: A, B, and C. They represent
the ' fiie'sability to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of asphalt and concrete . A
tire marked C may have poor traction performance .
Warning: Thetr.ction grade assigned to this tire is based on braking (straight-ahead) traction tests and· doellnot include cornerillg (turning) tractlon.
TEMPERATURE -A, B, C
The ·temperature grades are A (the highest), B, andC, representing the tire's
resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditio 'ns on a specified indoor laboratory test wheel.
Sustained 'high temperature can cause the material of the tire to degenerate
and reduce tire
life, and excessive temperature can lead to sudden tire failure .
The grade C corresponds to a level of performance which all passenger car
tires must meet under the Federat Motor Vehicle Safety Standard No.
109 . Grades B and A represent higher levels of performance on the laboratory test
wheel than the minimum required by law.
Warning: The
temperature grade for Ihis tire is established for a tire that
is properly inflated and not overloaded. Excessive speed, underinllaiion, or excessive loading, either separately or in combination, can cause heat
buildup and possible lire failure.
