the drain valve on the right-hand side of the engine at the water
inlet elbow and a little to the rear of the generator as shown *
in figure 27. After the liquid has drained off, refill the cooling
system with warm water, run the engine for a few moments, and
drain the system. Repeat this operation until the water is clean |
when it is drained.
In cases where the accumulation of rust and scale is so great that t
this method does not clean the system sufficiently, the flushing [
operation should again be repeated after one or two handfuls of
sal soda have been added. Care must be taken, of course, that the ,
cooling system is thoroughly flushed after this operation to clean
out all traces of the sal soda, and that none of the solution is ;
allowed to reach the car finish. >

A gasoline filter is provided at
the bottom of the fuel pump on
the front left-hand side of the
engine. Any accumulation of
water or sediment should be
cleaned out when it can be seen
in the glass bowl.
The bowl may be removed by
unscrewing the thumb nut on
the underside of the bowl and
swinging the yoke to one side.
The screen strainer at the top
of the bowl usually comes off
with the bowl but if it does
not, it may be removed by pulling it straight down.
Any dirt on the strainer should be washed off with gasoline
and the bowl should be wiped clean. The bowl should then
be reinstalled with the screen on top. Make sure the bowl
seats properly against the cork gasket at tl..e top of the filter,
Fig. IS. The gasoline filter should be
removed and cleaned whenever water
or sediment appears in the bowl.

The strainer on the carburetor
where the gasoline enters should also
be cleaned periodically. It may be
removed by disconnecting the feed
pipe, removing the two cap screws

The carburetor intake silencer serves also as an air cleaner.
This cleaner is designed to catch any dust or lint in the air
before it is drawn into the carburetor. It is automatic in opera-
tion and requires no attention other than periodic cleaning.
The mileage at which the air cleaner requires attention depends
entirely upon the conditions under which the car is operated.
For normal driving in cities and on hard surfaced roads, cleaning
once every 6000 miles is
sufficient. Under extreme
conditions, however, such
as continuous driving on
dusty roads or in localities
where there is considerable
dust in the air, cleaning may
be required as frequently as
every 2000 miles.
The air cleaner may be
lifted out, as shown in
figure 30, after the cover
of the intake silencer has
been removed. The cover
