44 Cooling System
Antifreeze
General
DANGER
Coolant is toxic; risk of poisoning.
DO NOT drink coolant. Use proper hand
protection when handling. Keep coolant
out of reach of children and animals.
Failure to follow these precautions can
cause serious illness or death.
CAUTION
Never add coolant to a hot or overheated
engine this can result in engine damage.
Allow the engine to cool first.
CAUTION
If the recycled antifreeze or coolant
has been passed through a fractional
distillation or similar process that has
removed all hazardous and contaminating
materials, including dissolved solids
and acids, will produce a sufficient base
antifreeze. Correctly inhibited to meet
the standard, it can be regarded as a new
coolant which is fully accepted.
Antifreeze additives not only protect the
cooling system from freezing but also
against corrosion and cylinder liner pitting.
Antifreeze typically comes in one of
two glycol types, ethylene or propylene.
Propylene antifreeze is NOT recommended
for use in a Volvo engine. There is also
regular and extended life antifreeze. If
the vehicle is delivered with extended life
coolant, there is a label attached to the surge
tank.
Note: DO NOT mix regular and extended
life antifreeze. DO NOT use extended life
antifreeze unless it is of a type approved by
the engine manufacturer.
Regardless of the type and make, acceptable
antifreeze or premixed coolant must meet
or exceed the standards ASTM D 5345 and
ASTM D 4985, and be formulated for heavy
duty diesel engines.
