1997 CHEVROLET TRACKER oil temperature

What Kind of Oil to Use
Oils recommended for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API).
Do not use any oil which
does not carry this Starburst symbol.
I:
If you change your
own oil, be sure you
use oil that has the
Starburst symbol on
the front of the oil
container. If you have
your oil changed for
you, be sure the oil put
into your engine is
American Petroleum
I J
Institute certified for
gasoline engines.
~~~ ~~~~~~
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

As shown in the chart, SAE 1OW-30 is best for your
vehicle. However, you can use
SAE 5W-30 if it’s going
to be colder than
60°F ( 16°C) before your next oil
change. When it’s very cold, you should use
SAE 5W-30. These numbers on an oil container show
its viscosity, or thickness.
Do not use other viscosity
oils, such as
SAE 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst’’ symbol. Failure to use the
recommended oil can result in engine damage not
covered
by your warranty.
GM Goodwrench’ oil meets all the requirements for
your vehicle.
If you are
in an area where the temperature falls below
-20°F (-29”C), consider using either an SAE 5W-30
synthetic oil or an
SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don’t add anything to your oil. Your Geo dealer is ready
to advise if you think something
should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:
0
0
0
0
0
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving
in stop-and-go traffic).
You operate your vehicle in dusty areas or
off-road frequently.
You frequently tow a trailer or
use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner. If any one
of these is true for your
vehicle, then you need to change your oil and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs first.
If none of them is true, use the long triphighway
maintenance schedule. Change oil and filter every
7,500 miles (12 500 km) or 7.5 months -- whichever
occurs first. Driving a vehicle with a
fully warmed
engine under highway conditions causes engine oil to
break down slower.

Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil
is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
3. Pull out the filter.
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
0 In hilly or mountainous terrain.
When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See “Scheduled Maintenance Services”
in the Index.

Front Axle
When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
“Periodic Maintenance Inspections” and “Scheduled
Maintenance Services” in the Index.
How to Check Lubricant
If the differential is at operating temperature (warm),
add enough lubricant to raise the level to the bottom of
the filler plug
hole.
If the differential is cold, add enough lubricant to raise
the level to 1/2 inch
(I 2 mm) below the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind
of lubricant to use. See “Recommended Fluids and
Lubricants”
in the Index.
Engine Coolant
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.
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant.
A 50/50 mixture of water and the proper coolant will:
0 Give freezing protection down to -33°F (-36°C).
0 Give boiling protection up to 258°F (125°C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.

Maintenance Schedule
Short Trip/City Definition
Follow the Short Trip/City Maintenance Schedule if any
one
of these conditions is true for your vehicle:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
You frequently tow a trailer or use a carrier on top of
your vehicle.
If the vehicle is used for delivery service, police, taxi
or other commercial application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions
cause engine oil to breuk
down sooneE
