Coolant - Filling
I CAUTION
If a boiler is connected to
the engine, follow the filling
procedure given by the manu-
facturer of the boiler. If the boiler
is above the engine in the boat,
first fill the heat exchanger, the
boiler, and top up with coolant
the recovery tank located above
the boiler.
Make sure not to overfill the
heat exchanger when filling with
coolant. If too much coolant has
been added, drain part of the
coolant.
Mix the anti-freeze with water in a
clean container before filling the
heat exchanger. The coolant must
be totally free from dust. Fill the
exchanger slowly not to introduce
air into the coolant system.
Refer to the chapter TECHNICAL
DATA to know the coolant capac-
ity of the heat exchanger. For Keel
Cooling system or when using a
water boiler, the coolant capacity
must be adapted according to the
pipes length and the tank capacity.
To fill the coolant system :
1. Turn the coolant filler cap
slowly to the first stop and let any
pressure escape from the system
then remove the cap.
2. Check that the drain plugs are
properly tightened.
3. Add coolant through the heat
exchanger filler port to the correct
level.
4. Check the coolant level in the
recovery tank (if fitted). Top up if
necessary.
5. Start the engine and let it oper-
ate few minutes at idle. Stop the
engine, wait few minutes and
check the coolant level in the
heat exchanger and in the recov-
ery tank. Top up if necessary.
