Day-to-day addition of coolant is done from the reservoir
tank. When adding coolant to the radiator, DO NOT remove
the radiator cap until the unit has completely cooled. Make
sure the coolant level in the reservoir tank is always between
the "H" and the "L" markings.
If adding coolant/antifreeze mix to the
radiator, DO NOT remove the radiator cap
until the unit has completely cooled. The
possibility of
hot! coolant exists which
can cause severe burns.
