Radiator and condenser
Check the radiator and condenser and clear any foreign objects.
If either of the above parts are extremely dirty or you are not sure of
their condition, have your vehicle checked by your Toyota dealer.
CAUTION
■ When the engine is hot
Do not remove the radiator cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing burns or other injuries.
NOTICE
■ When adding engine coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture 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 damage to parts or paint.
CAUTION
■ When the engine is hot
Do not touch the radiator or condenser as they may be hot and may cause
burns.
