One can fill the engine via the filling cap on the exhaust
manifold. Fill up till the level is just below the filling cap.
When the engine is on temperature the liquid will expand
and the redundant liquid will be pressed into the expansion
tank. This tank has to be filled up till the mark. When
cooling liquid is not available clean fresh water could be
used with an additive of anti freeze. When using water with
anti freeze the right mixture has to be calculated according
to the information of the supplier of the anti freeze. When
the cooling is based on keel cooling or radiator cooling the
capacity of these coolers and piping has to be taken into
account calculating the right mixture. The cooling liquid in
the engine is pressurised and has a boiling point above
212°F (100°C). The temperature switch in the thermostat
housing switches at 230°F (110°C). When keel cooling or
radiator cooling is applied the cooling system is not
pressurised. There should be a special cap on the
manifold without valves leaving the connection to the
expansion tank open. Refer to the manual on keel cooling
and radiator cooling.
