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 FULLº and LOWº lines on
the reservoir.  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 LOWº line, add 
coolant.  Bring the level up to the FULLº 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 
engine 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.
