Look at the see-through coolant res-
ervoir when the engine is cold. The
coolant level is satisfactory if it is be-
tween the FULLº and LOWº lines on
the reservoir. If the level is low, add
ethylene-glycol type coolant.
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the LOWº line, add
coolant. Bring the level up to the FULLº 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 ra-
diator, 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.
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
CAUTION! Coolant type selection
Your coolant must contain ethylene-gly- col antifreeze. In addition to preventingfreezing and subsequent damage to the
engine, this will also prevent corrosion. Further supplemental inhibitors or addi-
tives are neither needed nor recom- mended.
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 rec-
ommend 50% solution be used for your
Toyota, or a sufficient quantity to provideprotection to about -35 C (-31 C).
Do not use alcohol type antifreeze
or plain water alone.
NOTICE
To check the fluid level, simply look at
the see through reservoir. The level
should be between the MAXº and
MINº 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 prob- lem.
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

172line. This brings the fluid to the correct
level when you put the cover back on.
Use only newly opened brake fluid. Once
opened, brake fluid absorbs moisture
from the air, and excess moisture can cause a dangerous loss of braking.
CAUTION!
Take care when filling the reservoir
because brake fluid can harm your
eyes and damage painted surfaces.
If fluid gets in your eyes, flush your
eyes with clean water.
If you spill the fluid, be sure to wash it off with water to prevent it from
damaging the parts or paint.
NOTICE
Check the fluid level through the reser-
voir. If necessary, add automatic trans-
mission fluid DEXRON [
-II or III.
If the vehicle has been driven around
80 km/h (50 mph) for 20 minutes (a little more in frigid temperatures), the fluid is
hot (60 C ' 80 C or 140 F ' 175 F). You
may also check the level when the fluid is cold (about room temperature, 10 C
' 30 C or 50 F ' 85 F) if the engine has
not been run for about five hours. Clean all dirt from outside of the reservoirtank and look at the fluid level. If the fluid is cold, the level should be in the COLDº
range. Similarly, if it is hot, the fluid level
should be in the HOTº range. If the level
is at the low side of either range, add auto-
matic transmission fluid DEXRON
[
-II or
III to bring the level within range.
To remove the filler cap, turn it counter-
clockwise and lift up. To reinstall it, turn it
clockwise. After replacing the filler cap,
visually check the steering box case, vane
pump and hose connections for leaks or damage.
CAUTION!
The reservoir tank may be hot so be
careful not to burn yourself.
Avoid overfilling, or the power steering could be damaged.
