CLEANING AND REPLACING THE RADIATOR CAP
HANDLING OF RADIATOR CAP
Inside the radiator, the high pressure steam occurs and it may cause personal injury.
Do not loosen or remove the radiator cap when the coolant is under high pressure and temperature.
Stop the engine before removing the radiator cap.
Allow enough time for the coolant to cool down before removing the radiator cap.
A loose radiator cap will let hot steam and coolant escape from the cooling system during operation
and it may cause burns.
