Carefully remove the radiator cap and
check the inside of the radiator. If you
cannot see the coolant, add ethylene−
glycol type coolant for a proper corro-
sion protection of aluminum compo-
nents.
The coolant level in the reservoir will vary
with the traction motor temperature. Check
and add the coolant when the traction
motor is cold.
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 EV
service station 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
traction motor is hot.
Coolant type selection
Use of improper coolants may damage
your traction motor cooling system. Your
coolant must contain ethylene−glycol type
coolant for a proper corrosion protection
of your traction motor that contains alumi-
num components. Use "TOYOTA Long
Life Coolant" or equivalent.
In addition to preventing freezing and sub-
sequent damage to the traction motor, 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 capac-
ity of the cooling system is given in Sec-
tion 9.
We recommend to use 50% solution for
your Toyota, to provide protection down to
about −35
_
C (−31
_
F). When it is ex-
tremely 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.
