FULL-PRESSURE
ENGINE
LUBRICATION
Long, trouble-free engine
operation is assured by
full-pressure engine lubrication.
Oil is pumped under
pressure to the overhead
valve assembly, crankshaft
bearings, camshaft, connecting
rods and rocker arm %«^^
shafts, while a pressurized
jet of oil is directed to the cylinder walls and piston pins.
An oil filter, provided at no extra cost, minimizes wear by
filtering abrasive particles from the oil. Linked to the new
oil pump is a vacuum pump which assures dependable
windshield wiper operation.
HYDRAULIC VALVE SILENCERS
Cadillac hydraulic valve silencers automatically compensate
for any minute play or lash in the valve linkage, and thus
always maintain zero clearance between the tappets and
valves. This assures quieter engine operation, full seating of
valves for maximum compression and top engine efficiency.
EFFICIENT ENGINE COOLING
The large bore, short stroke design of the Cadillac engine
minimizes piston friction and exposes less cylinder wall
surface to the flame from the burning fuel-air mixture.
Therefore, more heat energy from the burning fuel goes into
driving the car and less heat must be absorbed by the cooling
system. As a result, Cadillac achieves highly efficient
cooling with a compact radiator unlike the bulky, oversize
units required with less efficient engines. Provision is made
to bring the engine quickly to its most efficient operating
temperatures by permitting the water to circulate only
through the cylinder block and head during warm-up. When
proper engine operating temperatures are reached, a thermostat
opens and permits the water to flow through the radiator
for the cooling needed to maintain the correct temperature.
