Cold Weather Operation
If the engine is in good mechanical condition 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, winterfront, etc., can make winter operation easier. Contact your
authorized 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. Accessories should be designed to be easily disconnected when
switching to driving in warmer weather so they do not affect the operation of the engine.
