CAUTION
Never remove the radiator cap under any conditions while the engine is running!
Failure to follow these instructions could result in damage to the cooling
system and/or personal injury. To avoid having scalding hot coolant or steam
blow out of the radiator, use extreme care when removing the radiator cap
from a hot radiator. Wait until the engine has cooled, then wrap a thick cloth
around the radiator cap and turn it slowly to the first stop. Step back while
the pressure is released from the cooling system. When you are sure the pressure
has been released, press down on the radiator cap (with the cloth still in
position), turn and remove the cap.
