Cooling System, Cleaning
WARNING!
All coolant is hazardous and harmful to the
environment. Do not consume. Coolant is flammable.
IMPORTANT:
Never clean the cooling system if there is any risk of
freezing,
since the cleaning solution does not have any
antifreeze properties.
IMPORTANT:
It
is extremely important that the correct concentration
and volume of coolant is added to the system.
Mix in a separate clean vessel before filling the cooling
system. Make sure that the liquids mix.
IMPORTANT:
Always
follow local safety instructions and regulations.
Cooling performance is reduced by deposits in the
radiator and cooling galleries. The cooling system
should be cleaned out when the coolant is changed.
1 Empty the cooling system. Refer to Coolant,
Draining, page 78.
2 Put a hose into the expansion tank filling hole and
flush with clean water, as specified by Volvo Penta–
refer to section Water quality in Technical
Data, page 96 until the water draining out is
completely clear.
3 If there should still be some contamination left after
flushing for a long time, cleaning can be done with
coolant. Otherwise, continue as in item 8 below.
