8.1.2. Starting of cold engine at low temperatures
At ambient air temperatures below –25° C (when the engine filled with
lowviscous oil) and below –15° C (when the engine filled with winter grade
oils) the following methods of engine warmingup are recommended prior to
engine starting:
a) engine heating with hot water. With the drain cock of the cylinder block
opened, hot water of 70–80° C is being poured in the radiator until water tem
perature reaches 30–40° C in the engine cooling system and warm water flows
from the drain cock. It is recommended to pour the water into the system swiftly
and continuously. To avoid water freezing in the engine radiator, hood the grill
with the radiator cover.
b) filling the engine with hot oil. In this case drain oil from the engine into
clean dishware. The oil should be heated up to 70–80° C and poured into the
engine right before starting.
Never start and run the engine with the empty cooling system. At long
term parking to avoid radiator and engine freezing, drain water from the cool
ing system and watch that all water was drained and it did not freeze in the
radiator and cylinder block drain cocks. For this purpose prick the cocks. To
expedite water drain from the system, open the radiator filler cap. When wa
ter is drained leave the cocks open.
8.1.3. Engine Stopping
Prior to engine stopping let it run for 3–5 min. at medium speed and then
at idle speed so as to reduce the temperature of coolant, oil and turbocharger.
To stop the engine release the accelerator pedal, turn off the instruments
with the key and battery switch.
8.2.VEHICLE DRIVING
It is recommended to start vehicle driving with the engine warmed up. If
there is no such possibility and the engine is warming up on the moving vehi
cle it is advisable at low temperature of ambient air and after prolonged park
ing to drive some time at low gears and low engine speed. As oil warms up it is
necessary to shift to higher gears in succession.
After wading, driving through heavy rain or after washing the vehicle brak
ing surfaces become coated with moisture. This will affect braking efficiency
until disks, drums and brake linings are dried by intermittent light application
of the brakes.
