Venting cock in cooling system
Check that the cooling system is properly vented by
carefully opening the vent cock after the engine
has been started and has reached operating temper-
ature. This will evacuate any air remaining in the sys-
tem.
Seawater filter, checking/cleaning
Volvo Penta offers two types of seawater filter. One
is a smaller filter with a transparent perspex cover,
and the other is larger and has a metal cover.
The filter cleaning intervals depend largely on operat-
ing conditions and can be determined according to
experience after operating your boat for a time. If
necessary, clean the filter more often than specified
in the maintenance schedule.
It is vital that the flow of seawater is never re-
stricted in any way.

system.
1. Remove cover (1) and lift up the insert.
2. Clean the insert and housing (2).
3. Reinstall the parts as shown in the figures below.
