Oil Pressure Gauge; Engine Temperature Gauge - Chevrolet Chevy II 1965 Owner's Manual

OIL PRESSURE GAUGE
The oil pressure gauge indicates the pressure at which oil is being delivered to the various parts of
the engine requiring lubrication. Pressures registered by the gauge may vary according to outside air
temperatures or weight of oil being used. Oil pressure of a cold engine being operated at a given speed
will be somewhat higher than when the engine is at normal operating temperature at the same speed .
Prolonged high speed operation on a hot day at the given speed will result in somewhat lower oil pres- ·
sure readings.
ENGINE TEMPERATURE GAUGE
Showing engine coolant temperature, gauge readings will vary with air temperature and operating
conditions. Hard driving or prolonged idling in very hot weather may produce above normal readings. The
ignition switch must be on for accurate readings.
TACHOMETER
CLOCK
Reset the clock, if your car is so equipped, by pulling out the knob and turning
the hands clockwise if slow, counterclockwise if fast. This will, if the clock error
is three minutes or more, automatically compensate for time gain or lag. Several
settings, several days apart, may be needed to properly adjust the clock mecha-
nism. Have your clock cleaned and oiled by a competent clock service man at
least every two years.
The tachometer indicates the speed of the engine in revolutions per minute .
The colored area between 5000 and 5500 rpm, indicates the maximum speed
which the engine should be run in anyone gear position.
