Cold Weather Precautions
IMPORTANT:
Coolant of a suitable chemical composition must be
used all year round to protect the engine against
internal corrosion, cavitation and freeze bursting.
This even applies when there is no risk for freeze
damage, to make sure the engine always has a
complete corrosion protection.
•
Drain sea water from the heat exchanger and loosen
the impeller pump cover.
•
Check that all water drains out otherwise residual
water may cause freeze bursting.
The risk of freeze bursting can be reduced by running
the engine when on land with a mixture of 40% coolant
and 60% fresh water through the sea water system
before the engine is switched off. Connect a garden
hose to the impeller pump (the sea water hose from
the intakes) and put the other end into a bucket of the
glycol mixture. Start the engine and let it idle. Be ready
to stop as soon as the bucket is empty.
Use a container to collect the coolant from the exhaust
outlet and hand it in to a recycling station.
