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.
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.
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.
