1938 LaSalle Production - GM Heritage Center

Any adjustments to the automatic choke mechanism
should be made only at an Authorized Service Station.
Air Cleaner—Your LaSalle car is fitted with an air
cleaner of the "oil bath type," which operates very efficiently
in removing dust from the air drawn into the engine. As
this type of cleaner accumulates considerable dust and
dirt, it requires regular cleaning every 2,000 miles, or
oftener if extreme conditions are encountered.
The cleaner is cleaned and re-oiled in the following
manner:
Remove the gauze unit and wash thoroughly
in gasoline, taking particular care to
wash all the accumulated dirt and dust out of
the wire mesh.
Dry all the units thoroughly, either with compressed
air or an adequate drying period.
Pour one pint of S.A.E. 50 engine oil (S.A.E.
40 in winter) in the reservoir and assemble the
wire mesh and cap.
NOTE:
mesh.
NO oil should be placed on the wire
Gasoline Filter—A gasoline filter is provided at 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. Remove the bowl by
unscrewing the thumb nut and swinging the yoke to one
side. If the screen strainer sticks, remove it by pulling
straight down.
Any dirt on the strainer should be washed off with gasoline,
and the bowl should be wiped clean. Then reinstall
screen and bowl, making sure the bowl seats properly against
the cork gasket, and tighten.
Other Service Operations—Major service operations
on the engine, such as valve grinding, replacement of bearings
or reconditioning of cylinders, should be performed only by
experienced workmen having the necessary instructions and
pequiment.
