2. The cooling system should be flushed and refilled with fresh antifreeze-coolant even if the inside of the radiator looks clean.

    The answer is TRUE!

Some additives in anti-freeze coolant, such as anti-corrosive chemicals, can be depleted with time, yet the anti-freeze coolant looks OK. Regular flushing of the cooling system and replacement of anti-freeze coolant helps avoid a later, and bigger, expense in radiator repair.
