Look at the see−through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the F" and L" lines on the reservoir.
If the level is low, add ethylene−glycol
type coolant for a proper corrosion
protection of aluminum components.
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the L" line, add
coolant. Bring the level up to the F" 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, 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 TOYOTA Long Life
Coolant" or equivalent.
In addition to preventing freezing and
subsequent damage to the engine, this
type of coolant will also prevent corrosion.
Further supplemental inhibitors or additives
are neither needed 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 Section
8. We recommend to use 50% solution for
your Toyota, to provide protection down to
about −35
C (−31 F). When it is extreme-
ly cold, to provide protection down to
about −50 C (−58 F), 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.
