Use only the best quality of rubber

and the rubber particles clog up the
system. Go over hose connections in
the spring. because some antitrceze
solutions have deleterious effect upon
the rubber. Also they have scum in

Not all of the cooling of the engine
is effected by water; but lubricating oil
plays an important part, as II cools
the bearings. Keep tho crankcase
clean; it cools the oil. 1t has been
found that gasoline washes the luhri
mixture of gasoline and oil runs into
the crankcase. where in time 1t destroys
the lubriccatinG qualities of the oil
For this reason the oil in the crank
case should be drained and replaced
with new oil every l.5O0 miles. If
this is no, done the oil viii be unable

The average working temperature OF
IS oil in summer is higher than in winter.
and so oil OF the same body will be
thinner. Sometimes il is advisable to
use a grade heavier oil in summer. In
excessively hot spells an especially
heavy grade of oil may be required TO
maintain the oil at the proper con-
sstency in operation. When heavier
oil is used care should be taken not
TO work the engine too hard before it
IS warmed UP. Buy oil only from re-
liable rciiners.
