14. COLD WEATHER OPERATION
14.1 PRECAUTIONS
FOR LOW TEMPERATURE
If the temperature becomes low, it becomes difficult to start the engine, and the
coolant may freeze, so do as follows:
14.1.1
FUEL
AND LUBRICANTS
Change to fuel and oil with low viscosity for all components.
For details of the
specified viscosity, see 20. USE OF FUEL, COOLANT AND LUBRICANTS
ACCORDING
TO AMBIENT TEMPERATURE.
14.1.2
COOLANT
1..1.,..,,.,.
A
WARN'NG
Keep antlfreeze fluid away from an open flame. Never smoke when
NOTICE
Never use methanol, ethanol or propanol based antifreeze.
Where no permanent antifreeze
is available,
an ethylene glycol antifreeze
without corrosion inhibitor may be used only for the cold season. In this case,
clean the cooling system twice a year (in spring and autumn). When refilling
the cooling system, add antifreeze in autumn, but do not add any in spring.
Absolutely avoid using any water leak preventing agent irrespective of whether
it is used independently or mixed with an antifreeze. Do not mix one antifreeze
with a different brand. For details of the antifreeze mixture when changing the
coolant, see 20.2.3 ANTIFREEZE.
Use a Permanent Antifreeze
(ethylene
glycol
mixed with corrosion
inhibitor,
antifoam
agent, etc.) meeting
the
standard requirements as shown below. With permanent antifreeze, no change
of coolant is required for a year. If it is doubtful that an available antifreeze
meets the standard
requirements,
ask the supplier of that antifreeze
for
information.
