Downloaded from www.Manualslib.com manuals search engine Oil Identification Logo
A logo (symbol) has been developed to help you select the oil you should use,
and it probably will be included on oil cans sometime during 1983. The top
portion of the logo shows the oil quality by API designations such as SF, SFI
CC, or others. The center portion of the logo will probably show the SAE
viscosity grade, such as SAE 5W-30. "Energy Conserving," shown in the lower portion, indicates that the oil has fuel-saving capabilities.
Change Intervals
The oil and oil filter change intervals for your engine are based on the use of
SF-quality oils and high-quality fi~ers such as AC oil filters. Using oil other
than SF-quality, or oil and filter change intervals longer than
recommended could reduce engine life. Damage to engines due to improper
maintenance or use of incorrect
oil quality and/ or viscosity is not covered by
the Chevrolet new car warranties.
Your engine was
filled with a high-quality engine oil when it was built. You do
not have to change this oil before the first recommended change interval.
Oil
and filter change intervals depend upon how you use your vehicle. The
following should assist in determining the proper oil and fi~er change intervals:
TVPEOFUSE CHANGE INTERVAL
• Operating
in dusty areas.
• Towing a trailer.
• Idling for extended periods andlor low speed operation such as found • Change engine oil and filter every
in police, taxi or door-Ie-door de-livery service. 3,000 miles (4 800 kilometers) or 3
rn.onths, whichever comes first.
• Operating when outside tempera-tures-remain below freezing and when most trips are less than 4 miles' (6 kilometers)~
• Operating on a daily basis, as a • Chan:ge engine oil every 7,500 general rule, for several miles and miles (12 000-km) or 12 months,
when none of the above conditions whichev.er comes first. Change en·
apply. gine oil filter at first oil change. then every other oil change if mileage determines· when you change oil. If time determines change intervals, change the filter with each oil change.
Engine Oil Additives
Engine oils contain a variety of additives. Your engine should not need any
extra additives
K you use the recommended oil quality and change intervals. However, H you think your engine has an oil-related problem, a supplemental
additive ("GM Engine Oil Supplement") is available that may solve your problem without causing other difficuHies. Consu~ your dealer who can provide
you
w~h this tested and approved additive.
Used Oil Disposal
Do not dispose of used engine oil (or any other oil) in a careless manner such
as pouring it on the ground, into sewers, or into streams or bodies of water.
Instead, recycle it by taking it to a used oiL collection facility which may be
found
in your area. If you have a problem disposing of your used oil, it is
suggested that you contact your
dealer or a service station.

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), or if
coolant is dirty or discolored, see your dealer for a cooling system check.
NOTICE: rr you use the proper quality antifreeze, there is no need to add extra inhibitors or additives which claim to improve the system. They may be harmful to the proper operation of the system.
Adding Coolant
CAUTION: To help avoid the danger of being burned, do not remove the radiator cap while the engine and radiator are stili hot. Scalding fluid and steam can be blown out under pressure if the cap is taken off too soon.
1. When the engine is cool, remove the radiator cap.
• 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.
2. Add enough water and ethylene glycol anmreeze (meeting GM Specification 1825-M) to provide the required cooling, freezing and
corrosion protection. Use a solution that is at least 50 percent antifreeze
but no more than 70 percent antHreeze. Fill the radiator to the base of the
filler neck and fill the coolahUocave,y lank to at or above the "Full Hot" mark. Put the recovery tank cap back on.
3. Run the engine, with the radiator cap removed, until the upper radiator
hose is
hot. 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 on the radiator filler
neck.
II is Ihe owner's responsibility 10:
• Maintain cooling system freeze protection at -37°G (-34°F) to ensUre
protection against corrosion and loss of coolant from boiling. (A SO/SO mixture of water and ethylene glycol antifreeze will provide freeze
protection to -37°G or -34°F.) You should do this even if you don't
expect freezing temperatures. Periodic
replacement of coolant is needed to replace the anti-corrosion additives that wear out with use. Coolant that
has become dark in color shows that it needs to be changed for this reason.
• Add ethylene glycol base antifreeze that meets GM SpecHication 1825-M
when antifreeze has to be added because of coolant loss or for more
protection against freezing at temperatures less than stated.
NOTICE: Do not use methanol-base antifreeze, or alcohol, . or plain water alone, in your vehicle at anytime. They will boil ata 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.
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 oullet on the engine block. The same
thermostat is used in both winter and summer. When a replacement is needed, AG-Oelco paris are recommended.
