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, engine coolant filler cap, ra-
diator 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.
CAUTION!
To prevent burning yourself, do not
remove the radiator cap when the
engine is hot.Coolant type selection
Your coolant must contain ethylene-gly-
col antifreeze. In addition to preventing
freezing 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 provide
protection to about -35C (-31F).
NOTICE
Do not use alcohol type antifreeze
or plain water alone.
