CLEANING OR REPLACING RADIATOR CAP
HANDLING OF COOLANT AND CAP
Do not loosen or remove the reserve tank cap and the radiator cap when the coolant is under high pressure and
high temperature.
High temperature steam and coolant will spray and could cause burns.
• When opening the cap, wait until the coolant cools down, and then slowly turn and open the radiator cap.
• The antifreeze is poisonous, so prevent it from contacting with skin. If the antifreeze gets into your eyes or on
your skin, flush the eyes or skin with plenty of water, and seek medical attention.
Securely close the cap after opening it.
