CAUTION
Do not use methanol-based or methoxypro-
panol-based antifreeze products. They can
severely damage the engine.
Never mix FUSO DIESEL LONGLIFE COOLANT
with other brands of long-life coolant or any
antifreeze or corrosion-preventive additives.
Doing so would reduce the performance of the
coolant. If a different long-life coolant has been
used and the FUSO DIESEL LONGLIFE COOL-
ANT is to be used, be sure to thoroughly flush
the cooling system.
Use the following table to determine the correct
concentration of FUSO DIESEL LONGLIFE COOL-
ANT according to the lowest temperature at which
your vehicle is to be operated.
FUSO DIESEL LONGLIFE COOLANT concentra-
tion (in volume percentage)
NOTE:
Vehicles are shipped with a 50% concentration of
FUSO DIESEL LONGLIFE COOLANT and can
therefore be used at temperatures down to –30°C
(–22°F).
CAUTION
Use FUSO DIESEL LONGLIFE COOLANT at a
concentration of between 50% and 60%. The
proper concentration under normal tempera-
tures is 50%. At a concentration below 30%, this
additive performs poorly as an anticorrosive,
while at a concentration exceeding 60%, it per-
forms poorly as an antifreeze.
