Oil identification marks 
Either or 
both API registered marks are
added to some oil containers to help 
you select the oil you should use. 
The API Service Symbol is located any- 
where on the outside of the container. The top portion of the label shows the oil 
quality by API (American Petroleum Insti-
tute) designations such as SH.  The cen- 
ter portion of the label shows the SAE vis- 
cosity grade such as SAE 5W-30.
Energy-Conserving   IIº shown in the low-
er portion, indicates that the oil has fuel-
saving capabilities.  Oils marked Ener-
gy-Conserving  IIº will have higher 
fuel-saving  capabilities than oil marked Energy-Conservingº. 
The ILSAC (International Lubricant Stan- 
dardization and Approval Committee)Certification  Mark is displayed on the front
of the container. Look at the see-through coolant res- 
ervoir when the engine is cold.  The 
coolant level is satisfactory if it is be-
tween the Fº and Lº lines on 
the res-
ervoir.  If  the level is low,  add ethylene-
glycol type coolant. 
The coolant level in the reservoir will vary 
with engine temperature.  However, if the level is on or below the Lº line, add cool- ant.  Bring the level up to the Fº line. Use only ethylene-glycol type coolant. See information in the next column. 
If the coolant level drops within a short 
time after replenishing, there may be a
leak in the system.  Visually check the ra- 
diator, hoses, radiator cap and drain cock 
and water pump. 
If you can find no leak, have your Toyota 
dealer  test the cap pressure and check for
leaks in the cooling system.
To prevent burning yourself, do not 
remove the radiator cap when the en- 
gine is hot.
CAUTION! Coolant type selection 
Your coolant must contain ethylene-gly- col antifreeze.  In addition to preventingfreezing and subsequent damage to the 
engine, this will also prevent corrosion. Further supplemental inhibitors or addi-
tives are neither needed nor recom- mended. 
Read 
the antifreeze container for informa-
tion on freeze protection.  Follow the 
manufacturer 's directions for how much 
to mix with water.  The total capacity of the
cooling  system is given in Part 8.  We rec-
ommend 50% solution be used for your
Toyota, or a sufficient quantity to provideprotection to about -35  C (-31  C).
Do not use alcohol type antifreeze
or plain water alone.
