Engine Start and Operation 205
Cold Weather Operation
If the engine is in good mechanical condi-
tion and the necessary preparations are
taken for cold weather operation, ordinary
cold weather will not cause difficulty in
starting or loss of efficiency.
Cold weather operation does require
changes in operating practices, maintenance
procedures, lubrication and fuel. Additions
to the vehicle, such as heated fuel filters,
fuel tank heater, engine block heater, win-
terfront, etc. can make winter operation
easier. Contact your Volvo Truck dealer for
the correct accessories and information
about installation.
If satisfactory engine temperature is not
maintained, increased engine wear will
result in higher maintenance cost. Acces-
sories should be designed to be easily
disconnected when switching to driving in
warmer weather so they do not affect the
operation of the engine.
For cold weather operation follow these
recommendations:
• When starting the engine in tempera-
tures below 32

F (0

C), use engine
lubricants of lower viscosity. See the
“Operator’s Manual, Maintenance and
Engine” for more information.
• When the temperature is below freez-
ing, make sure the concentration of
antifreeze in the coolant is sufficient to
prevent freezing. See “Operator’s
Manual, Maintenance and Engine” for
more information.
