tiOn, not to mention the necessity Of
more frequently filling the radiator

upon the face of the radiator have
the same tendency toward undue heat

removed with the aid OF the garden
hose, operated from the rear Of the
radiator
The best cleansing mixture for re-
moving the scale. grease. etc, from
the interior of the cooling tubes is
made by d1SSOIVlng half a pound OF
I've in a bucket of water and stirring
until thoroughly dissolved This
should be strained and the radiator
filled with the mixture. The engine
should then be run for five minutes
and allowed TO stand for a quarter
Of an hour. The mixture may then
be drained off and the radiator filled
with clean water The engine is
again run for a few minutes after
which the radiator is drained and re-
filled with a fresh supply of water,
The foregoing treatment will re-
move any grease deposits within the
radiator and is calculated to also
loosen the scale, which is drained off
