your Toyota dealer.
■
If the coolant level drops within a
short time of replenishing
Visually check the radiators, hoses,
engine/power control unit coolant reser-
voir caps, drain cock and water pump.
If you cannot find a leak, have your
Toyota dealer, test the cap and check for
leaks in the cooling system.
WARNING
■
When the engine is hot
Do not remove the engine coolant
reservoir cap.
The cooling system may be under
pressure and may spray hot coolant if
the cap is removed, causing serious
injuries, such as burns.
NOTICE
■
When adding coolant
Coolant is neither plain water nor
straight antifreeze. The correct mix-
ture of water and antifreeze must be
used to provide proper lubrication,
corrosion protection and cooling. Be
sure to read the antifreeze or coolant
label.
■
If you spill coolant
Be sure to wash it off with water to
prevent it from damaging parts or
paint.
Checking the radiator and
condenser
Check the radiator and condenser,
and clear away any foreign objects.
If either of the above parts is
extremely dirty or you are not sure
of their condition, have your vehicle
inspected by your Toyota dealer.
WARNING
■
When the engine is hot
Do not touch the radiator or con-
denser as they may be hot and cause
serious injuries, such as burns.

ing fan or radiator grille.
