if such is fitted. The symbol for water-in-fuel shall not
light in the display. If the symbol should light, the
water separator must be drained
6 Windscreens and rear view mirrors shall be whole
and clean
7 The trailer coupling shall be in good condition
8 The load shall be properly secured
9 The coolant level
The coolant level with a cold engine shall lie between
the MIN and MAX marks on the expansion tank. Fill
with coolant, Volvo recommend ready-mixed Volvo
Coolant VCS. If there is good quality water available,
concentrated Volvo Coolant VCS mixed with water
can be used instead.
Always use Volvo Coolant VCS, which contains an
anti-corrosion agent especially adapted to suit Volvo
engines. Mixing with other types of coolant can result
in inferior anti-corrosive properties resulting in
damage to the engine.
Maintenance 505
Drain the air tanks to check that
there is no condensation water.
Water in the air tanks is a sign that
the air drier is not functioning.
