Checking the engine coolant

level
Look at the see−through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the "FULL" and "LOW" lines on the
reservoir. If the level is low, add the
coolant. (For the coolant type, see
"Coolant type selection" described be-
low.)
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is below the "LOW" line, add cool-
ant. Bring the level between the "FULL"
and "LOW" lines.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, coolant reservoir cap and
drain cock and water pump.
If you can find no leak, have any autho-
rized Toyota dealer or repairer, or another
duly qualified and equipped professional,
test the cap pressure and check for leaks
in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the coolant reservoir cap
when the engine is hot.

Use of improper coolants may damage
your engine cooling system.

or similar high quality ethylene glycol
based non−silicate, non−amine, non−nitrite,
and non−borate coolant with long−life
hybrid organic acid technology. (Coolant

technology is a combination
phosphates and organic acids.)
"Toyota Super Long Life Coolant" is a mix-
ture of 50% coolant and 50% deionized
