Cooling System
General Coolant Information
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.
WARNING
DO NOT raise the engine hood if you see or hear steam or coolant escaping from
the engine compartment. Wait until steam or coolant cannot be seen or heard before
raising the hood.
DO NOT remove the coolant fill cap if the coolant in the surge tank is boiling.
Also, DO NOT remove the cap while the engine and radiator are still hot. Scalding
fluid and steam may be blown out under pressure if the cap is taken off too soon
and can cause personal injury.
WARNING
Coolant may be combustible. Coolant leaked or spilled onto hot surfaces or
electrical components can cause a fire. Clean up coolant spills immediately.
CAUTION
VOLVO Trucks North America does not recommend using plain water in the
cooling system. Water alone is corrosive at engine operating temperatures and does
not provide adequate boiling protection. The engine may develop corrosion and
cavitation problems in the engine and radiator, and the boiling point of the coolant
is lowered compared to a proper antifreeze and water mixture. Failure to follow
VOLVO Truck North Americas cooling system care/maintenance recommendations
can render the warranty invalid.
