Look at the see- through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the ºFULLº and ºLOWº lines on the
reservoir. If the level is low, add ethyl-
ene- glycol type coolant for a proper
corrosion protection of aluminum com-
ponents.
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the ºLOWº line, add
coolant. Bring the level up to the ºFULLº
line.
Always use ethylene- glycol type coolant
for a proper corrosion protection of alumi-
num components. 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
radiator, hoses, engine coolant filler cap,
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.CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
Coolant type selection
Use of improper coolants may damage your
engine cooling system. Your coolant must
contain ethylene- glycol type coolant for a
proper corrosion protection of your engine
that contains aluminum components. Use
ºToyota Long Life Coolantº or equivalent.
In addition to preventing freezing and sub-
sequent damage to the engine, this will
also prevent corrosion. Further supplemen-
tal inhibitors or additives are neither need-
ed nor recommended.
Read the coolant container for information
on freeze protection. Follow the manufac-
turer's directions for how much to mix
with plain water (preferably demineralized
water or distilled water). The total capacity
of the cooling system is given in Part 8.We recommend to use 50% solution for
your Toyota, to provide protection down to
about -35C (- 31F). When it is extreme-
ly cold, to provide protection down to
about -505C (- 585F), 60% solution is rec-
ommended. Do not use more than 70%
solution for better coolant performance.NOTICE
Do not use alcohol type antifreeze or
plain water alone.
