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
"Coolant type selection" described be-
low.)
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the "LOW" line, add
coolant. Bring the level up to the "FULL"
line.
If the coolant level drops within a short
time after replenishing, there may be a
"Toyota
leak in the system. Visually check the
radiator, hoses, drain cock and water
pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
Genuine
for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the coolant reservoir cap or
air release valve when the engine is
hot.
Coolant type selection
Use of improper coolants may damage
your engine cooling system.
Only use "Toyota Super Long Life Coolant"
or similar high quality ethylene glycol
type, see
based non–silicate, non–amine, non–nitrite,
and non–borate coolant with long–life hy-
brid organic acid technology. (Coolant with
long–life hybrid organic acid technology
consists of the combination of low phos-
phates and organic acids.)
"Toyota Super Long Life Coolant" is pre-
mixed with 50% coolant and 50% deion-
ized water. This coolant provides protec-
tion down to about –35 C (–31 F).
NOTICE
Do not use plain water alone.
