40 Cooling System
Coolant consists of clean water and
antifreeze. This mixture should never be less
than 40% antifreeze and 60% clean water or
more than 60% antifreeze and 40% clean
water. Mix the antifreeze and water to the
required concentration before adding to the
cooling system.
Note: DO NOT mix different products,
such as regular antifreeze and extended life
antifreeze.
Note: Volvo Trucks North America, Inc.
does not recommend the use of antifreeze
based on propylene glycol.
W2003082
Coolant, consisting of an antifreeze solution
in water, should be used year-round to
provide freeze and boil-over protection as
well as providing a stable environment for
seals and hoses. The solution needs to be
tested for proper additive levels at regular
intervals (see page 47 for testing SCA
levels), unless extended life antifreeze is
used. Adjust additive concentration if not at
the proper levels.
Note: DO NOT use antifreeze formulated
for automobile gasoline engines. These have
a very high silicate content that will clog the
radiator and leave unwanted deposits in the
engine.
