sion tank if the engine is hot. Hot coolant and
steam may spray out and cause burns. If the cap
has to be opened do it slowly to release the pres-

tion if it comes in contact with the skin.
Use a suitable container. Used coolant must be
disposed of as specified in national and interna-
tional laws and regulations.
