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 ethyl-
ene- glycol type coolant.
The coolant level in the reservoir will vary
with engine temperature. However, if the lev-
el is on or below the ”LOW” line, add coolant.
Bring the level up to the ”FULL” line.
Use only ethylene- glycol type coolant. 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
Your coolant must contain ethylene- glycol
antifreeze. In addition to preventing freez-
ing and subsequent damage to the engine,
this will also prevent corrosion. Further
supplemental inhibitors or additives are
neither needed nor recommended.
Read the antifreeze container for informa-
tion on freeze protection. Follow the
manufacturer’s directions for how much to
mix with water. The total capacity of the
cooling system is given in Part 8. We
recommend 50 % solution be used for
your Toyota, or a sufficient quantity to
provide protection to about –35
C (–31 F).
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
Checking brake fluid
To check the fluid level, simply look at
the see- through reservoir. The level
should be between the ”MAX” and
”MIN” lines on the reservoir.
It is normal for the brake fluid level to go
down slightly as the brake pads wear. So
be sure to keep the reservoir filled.
If the reservoir needs frequent refilling, it
may indicate a serious mechanical problem.
If the level is low, add SAE J1703 or
FMVSS No. 116 DOT 3 brake fluid to
the brake reservoir.
Remove and replace the reservoir cover by
hand. Fill the brake fluid to the dotted line.
This brings the fluid to the correct level when
you put the cover back on.
