the filter through 3/4 of turn. Make sure, that there is no leakage
of oil.
Oil pressure in the lubrication system of a warmed-up engine
of a new automobile at a speed of 60 km/h in direct gear and
when the oil cooler cock is open should be at least 343 kPa
(3.5 kgf/cm
2
). Oil pressure in a cold engine can be increased to
588 kPa (6kgf/cm
2
), and on a hot summer day it could be
dropped to 294 kPa (3kgf/cm
2
). Stop running the engine, when
oil pressure is dropped to 118 kPa (1.2 kgf/cm
2
). When driving
the automobile, watch the functioning of the oil pressure
transmitters. The low oil pressure warning transmitter must
operate at an oil pressure drop in the system down to 39-78 kPa
(0.4-0.8 kgf/cm
2
).
The low oil pressure warning lamp may light when the hot
engine is running at an idling speed, but the lamp must go out
immediately with an increasing crankshaft speed.
