LUBRICATION SERVICE AND PREVENTIVE MAINTENANCE
2-3
A new air cleaner element should be installed
every 30,000 miles. More frequent replacement of
the element may be necessary if the car is con-
stantly driven in dusty areas. The polyurethane
foam element should not be washed, oiled, tapped,
or blown out with an air hose. A visual inspection
of the element is recommended every Spring and
Fall to make certain that it is properly seated and
that there is no indication of dust leakage. If
damage is indicated at time of visual inspection,
the element should be changed. To replace ele-
ment, proceed as follows:
1. Remove cover from carburetor air cleaner.
2. Lift out element, remove sheet metal sup-
porting screen from element and discard old
element.
3. Wipe all dirt from inside air cleaner body
and screen.
4. Install screen in new element with element
sealing edges overlapping screen evenly.
NOTE: It is not necessary to oil the element
as it has already been oil-wetted by the
manufacturer.
5. Install element in air cleaner body, making
certain that it is properly seated, and replace air
cleaner cover.
d. Engine Oil Filter
The engine oil filter used on 1963 model
Cadillac cars is of the full-flow type incorporting
a throw-away element. It is recommended that the
element be replaced at 6,000 miles, and then each
six months or each 6,000 miles thereafter, which-
ever occurs first.
The full-flow type oil filter filters 100% of the
oil delivered by the oil pump. For this reason, it
is very important that the recommended oil filter
change intervals be followed.
The oil filter is mounted on the right side of the
front cover and attached to a support bracket,
which is mounted on a boss on the right side of the
engine. Fig. 2-3. Access to the filter is gained
from under the hood. Replacement procedure is
as follows:
1. Drain engine oil at recommended time or
mileage interval.
2. Unscrew element from filter base and dis-
card element.
3. Wipe gasket area of base clean.
4. Install new gasket in groove of new element.
Place a light film of silicone on top of gasket and
Figure 2-3 Engine Oil Filter
screw element onto stud of filter base by hand un-
til gasket touches filter base. Then tighten ele-
ment an additional 2/3 of a turn.
5. Add 5 quarts of oil to engine crankcase.
6. Operate engine at fast idle and check for oil
leaks at filter base.
7. After engine has run for 3 to 4 minutes, stop
engine and check oil level.
e. Positive Crankcase Ventilator
The positive crankcase ventilator unit installed
on all 1963 Cadillac vehicles should be serviced
periodically to insure continued efficient function-
ing of the unit.
At every engine oil change, the ventilator valve
should be removed and cleaned by soaking it in
carburetor cleaner. The shank end of a 3/32 inch
drill (or .080 inch -.090 inch wire) should be in-
serted in the threaded end of the valve to clean the
orifice inside the valve. After cleaning, an air
hose should be placed against the large hose con-
nector end of the valve, and the valve blown out
with air.
NOTE: Cleaning of the oil breather cap is
important because of the positive crankcase
ventilator. The breather must be cleaned and
re-oiled at every engine oil change.
4. Rear Axle
Check the lubricant level in the rear axle only
on the first inspection and add fresh lubricant if
necessary. The rear axle lubricant level should
be within 1/2 inch of the lower edge of the filler
hole. At subsequent engine oil changes inspect
rear axle assembly for external signs of leakage
and check lubricant level only if leakage is
evident.
