Keel cooler
How the cooling system in engines with
keel cooling should be drained depends
on the installation of the keel cooler.
Refer to the keel cooler manufacturer’s instructions for this.
Check using a coolant hydrometer whether the coolant is providing sufficient protection against freezing if total draining off
is not possible.
