INFORMATION
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 100° C. The temperature switch in the
thermostat housing switches at 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.
