Cadillac-LaSalle Preliminary Service Information
Fuel Tank and Exhaust System
Fuel tank capacity
The gasoline tank and lines on the 38-series V-8
cars are essentially the same as they were on the
corresponding 37-series cars. The 38-90 gasoline
lines are described in detail on page 15, under V-16
carburetion.
The 38-50 LaSalle exhaust system has only
minor changes, the most noticeable of which is
the eliminarion of the former tail pipe spreader,
which has been discontinued on all 38-series cars.
All 38-series Cadillac cars have the muffler
placed transversely across the chassis just behind

the gasoline tank, as indicated in Figs. 1 and 2,
page 6. This design is necessary because with
the lowered frames, conventionally placed mufflers
would have insufficient road clearance.
In addition, an expansion chamber is attached
to the exhaust pipe just ahead of the muffler.
The 38-90 uses a single muffler and exhaust pipe
similar to the 38-75 system. The two V-16 exhaust
manifolds discharge into a cross pipe which connects
with the single exhaust pipe leading down
along the left side of the frame.
The double-tooth roller steering gears and the
steering systems used on 37-series have been continued
on the 38-series cars with only minor
changes.
The 38-50 and 60 steering gears are mounted inside
the frame sidebar and are connected to the
intermediate steering arm with the familiar crossmounted
drag link.
The steering gear housings for series 38-65, 75
and 90 have been modified to suit frame changes,
while their lengthwise-mounted drag links have
been modified to suit new engine locations. The
Steering
38-65 gear is mounted inside of the frame sidebar
in the same manner as the 37-65 gear. The 38-75
and 38-90 V-16 gear resembles the 37-75 gear, as
it is mounted outside the frame sidebar with the
roller shaft extending inward, and is operated
through two universal joints.
Steering gear adjustments are all familiar. The
38-50 and 60 gears are adjusted the same as the
37-50 gear; the 38-65 the same as the 37-65; and
the 38-75 and 38-90 gear the same as the 37-75-
Adjustments of steering connections are the same
as for the corresponding 37-series.

The wheels, tire and rim sizes, and tire inflation
pressures are the same on 38-series cars as on the
corresponding 37-series, except for the 38-90 V-16,
which has the same size wheel equipment as the
38-75- The 38-series wheels are, however, of a
different make and consequently they are not
interchangeable with the 37-series wheels.
Wheel discs with integral hub caps are accessories
for all 38-series except 38-90, on which they
are standard. Wheel trim rings are accessories for
cars not fitted with wheel discs. Removal of wheel
discs requires the same prying tool as used on
37-series.
New drum type metal tire covers are used with
fenderwell spare wheels. These covers are hinged
to the fender at the front and locked down at the
rear. As the cover itself holds the wheel in the
well, the spare wheel may be lifted out as soon as
the cover is swung forward out of the way.
