alcohol is perhaps the best and this

When the car Is not used In the

been cracked because Of failure TO
do this.
To-day there Is littlo likelihood Of

TO prevent leakage around the
pump shaft the pump is furnished
with packing nuts. as shown In Figure

The radiator is always coupled to
the rest OF the system by a flexible
hose. as II it were rig.dly connected

is rotted the inner rubber will come
loose and often seriously check the
circulation of the water when new
hose is put on it Is a good practice To
put some shellac on the pipe to which
II is attached, rs the shcllac will do
much To prevent leak between the
hose and pipe.
