LUBRICATION SERVICE AND PREVENTIVE MAINTENANCE
joints should be checked for looseness. If the
seal is damaged or a joint loose, replace the
affected inner or outer tie rod pivot.
Special front suspension lubricant is provided
in one pound cans and is available from Parts
Warehouses. This lubricant is identified by Part
Number and the red colored label on the con-
tainer. Repacking guns used with the lubricant
have a red color band around the bottom of the
body cylinder. The red colored band on the re-
packing gun and label on the lubricant container
identify gun and lubricant.
The procedure for replacing and repacking the
upper and lower suspension arm spherical joint
seals is described in Section 4, Notes 11 and 12.
2. Engine
a. Engine Oil Recommendations
The original oil will perform satisfactorily dur-
ing the normal change interval specified on the
Engine Oil Change Interval and Viscosity Chart,
Page 2-8, because this oil meets General Motors
Standard GM 4745-M. The same chart should also
be referred to for factory recommendations if
additional oil should be necessary prior to the
normal change interval.
The use of proper engine oil is the best as-
surance of continued reliability and performance
from a Cadillac engine. The factory does not re-
commend oils by brand name, as assurance of oil
quality is the responsibility of the refiner. In-
stead, the factory recommends oils that, ac-
cording to their labels, are: (1) intended for
service "MS", and (2) represented as passing car
makers' tests or General Motors Standard GM
4745-M. Cadillac Servicemen should assist
owners in the selection of the proper oil that
meets the above requirements, as well as the
proper viscosity number for a particular area.
In areas where several brands of oil are available
that meet the above requirements, the choice of a
particular brand should be left to the discretion
of the owner.
In areas where the temperature seldom drops
below zero, most 10W oils are satisfactory for
easy starting of the engine. Where the temper-
ature is frequently below zero, a 5W-20 or 5W oil
is recommended; however, some 10W oils may be
satisfactory.
b. Adding Engine Oil
Always maintain the correct oil level. Oil
should be added when the level reaches the "Add
One Quart" mark on the dipstick. Do not fill a-
bove the "Full" mark or foaming may result.
c. Changing Engine Oil
The crankcase should be drained only after the
engine has been warmed to normal operating
temperature. The benefits of draining are mini-
mized if the crankcase is drained when the engine
is cold, as some suspended foreign matter will
cling to the sides of the oil pan and will not drain
with the slower moving colder oil.
The Engine Oil Change Interval and Viscosity
Chart, Page 2-8, will serve as a guide for the
proper oil change interval and oil viscosity to be
used at the prevailing temperature. It is unneces-
sary to change the oil for the occasional
unseasonably cold or warm day encountered during
the fall or spring season. The crankcase capacity
is 4 quarts. Do not add more than 4 quarts except
when changing oil filter element, in which case 5
quarts should be used.
3. Engine Accessories
a. Distributor
There are no external oiling provisions on the
1963 Cadillac distributor as it is permanently
lubricated and requires no periodic oiling. How-
ever, in the event the distributor is disassembled
and the shaft or breaker plate is removed, the
wick in the oil reservoir should be moistened with
light weight oil.
b. Breather Cap
Whenever the engine oil is changed, the copper
gauze in the filler cap should be cleaned in a
solvent and re-oiled with engine oil.
c. Carburetor Air Cleaner
The carburetor air cleaner, Fig. 2-2, on the
engines of all 1963 model Cadillac cars uses a
replaceable oil-wetted polyurethane foam element.
The element is cylindrical-shaped, and fits over a
perforated sheet metal supporting screen. The
screen also serves as a flame arrester in case of
backfire.
