Bear in the mind that antifreeze is poisonous.
The coolant level should be 30-40 mm above the MIN level
mark inscribed on the expansion tank.
Never mix the coolants of different grades. If the level of special
fluid in the system has dropped and fluid of the same grade is
not available, top up the system with clean soft rainy, snow or
boiled water.
Bear in mind that the freezing point of the antifreeze diluted
with water is higher. Fill the system with antifreeze of appropri-
ate grade at the first opportunity.
If the special coolant is not available, it is permissible to
use clean soft water. In this case, at the ambient temperature
below 0 °C proceed as follows:
- disconnect the hose from the expansion tank and lower it
to carry off steam from the radiator;
- when parking, drain coolant from the engine cooling
system and heating system.
Keeping the coolant temperature in a range of 80 to 90 °C
during operation of the automobile considerably decreases wear
of the engine and cuts down fuel consumption. The recom-
mended temperature is maintained by means of an automati-
cally operated thermostat and the shutters controlled by the
automatically operated thermostat and the shutters controlled
by the driver.
In cold weather, we recommend to encase the cooling system
for warmth-keeping.
The coolant temperature gauge located on the instrument
panel controls the temperature of coolant.
Besides this, the lamp with red light filter warns of coolant
overheating. The lamp goes on at the coolant temperature
between 91 and 98 °C for automobiles operating in regiones with
temperate climate, and at the coolant temperature between 102
and 109 °Ñ for automobiles operating in regiones with tropical
climate. When lighting the coolant temperature overheating
warning lamp, immediately determine and eliminate the cause
of overheating.
The rise of the coolant temperature may be caused by the
drop of coolant level in the radiator, loose tension of the fan belt,
faulty fan drive coupling, by movement of the automobile with
the closed shutters and with the closed valve of warmth-keeping
boot.
