11-2 In cold weather
• When vehicles are shipped from the factory,
genuine FUSO DIESEL LONGLIFE COOLANT
is added to the coolant in their cooling systems.
This additive combines both antifreeze and anti-
rust capabilities to sufficiently protect the cooling
system from freezing up. However, for added
safety, it is recommended that you have an
authorized dealer check that the coolant has a
proper concentration of the additive before win-
ter begins.
• Be sure to use coolant added with the FUSO
DIESEL LONGLIFE COOLANT or equivalent to
the recommended concentration. P. 12-48
CAUTION
Never mix FUSO DIESEL LONGLIFE COOLANT
with other brands of anti-freeze or anti-corro-
sion additives since these can detract from its
performance. If a different coolant additive has
been used and the FUSO DIESEL LONGLIFE
COOLANT is to be used, be sure to thoroughly
flush the cooling system.
The viscosity of the engine oil increases in cold
temperatures, sometimes making it hard to start the
engine, especially early in the morning. Therefore,
use an engine oil of a viscosity which suits the
weather conditions. P. 12-23
